Unsourced material may be challenged and removed.The first parts of the family were available in 1976; by 2013 the company had shipped more than twelve billion individual parts, used in a wide variety of embedded systems.All current models use flash memory for program storage, and newer models allow the PIC to reprogram itself. Program memory and data memory are separated. Data memory is 8-bit, 16-bit, and, in latest models, 32-bit wide. Program instructions vary in bit-count by family of PIC, and may be 12, 14, 16, or 24 bits long. The instruction set also varies by model, with more powerful chips adding instructions for digital signal processing functions. Low-power and high-speed variations exist for many types. Third party and some open-source tools are also available. Some parts have in-circuit programming capability; low-cost development programmers are available as well as high-production programmers.The CP1600 was a powerful processor for its era, implementing most of the PDP-11 minicomputer's instruction set architecture in a microcomputer package.This meant that communicating with a device required the device to watch for key memory locations being accessed on one machine cycle, and then read the data on the next. All of this complexity was repeated on the CPU side in the corresponding device driver.The PIC used simple microcode stored in ROM to perform its tasks, and although the term RISC was not used at the time, it shares some common features with RISC designs.The PIC, however, was upgraded with an internal EPROM to produce a programmable channel controller. http://veneziaps.com/updata/ndata/20200913055436.xml

The baseline and mid-range families use 8-bit wide data memory, and the high-end families use 16-bit data memory. The latest series, PIC32MZ is a 32-bit MIPS -based microcontroller. Instruction words are in sizes of 12-bit (PIC10 and PIC12), 14-bit (PIC16) and 24-bit (PIC24 and dsPIC). The binary representations of the machine instructions vary by family and are shown in PIC instruction listings.They are represented by the PIC10 series, as well as by some PIC12 and PIC16 devices. Baseline devices are available in 6-pin to 40-pin packages.Pointers are implemented using a register pair: after writing an address to the FSR (file select register), the INDF (indirect f) register becomes an alias for the addressed register. If banked RAM is implemented, the bank number is selected by the high 3 bits of the FSR.CALL and GOTO instructions specify the low 9 bits of the new code location; additional high-order bits are taken from the status register. Note that a CALL instruction only includes 8 bits of address, and may only specify addresses in the first half of each 512-word page.These devices are available in 6-pin SMD and 8-pin DIP packages (with two pins unused). A complex set of interrupts are available. Clocks are an internal calibrated high-frequency oscillator of 16 MHz with a choice of selectable speeds via software and a 31 kHz low-power source.The instruction set differs very little from the baseline devices, but the two additional opcode bits allow 128 registers and 2048 words of code to be directly addressed. There are a few additional miscellaneous instructions, and two additional 8-bit literal instructions, add and subtract. The mid-range core is available in the majority of devices labeled PIC12 and PIC16.The 17 series is not recommended for new designs, and availability may be limited to users.PIC17 devices were produced in packages from 40 to 68 pins.They are saved on every interrupt, and may be restored on return. http://thetokyopages.com/paddyspalmspub/temp/crown-xls-602-manual-espa-ol.xml

Depending on which indirect file register is being accessed it is possible to postdecrement, postincrement, or preincrement FSR; or form the effective address by adding W to FSR.PIC24 devices are designed as general purpose microcontrollers.Software can access ROM in 16-bit words, where even words hold the least significant 16 bits of each instruction, and odd words hold the most significant 8 bits. The high half of odd words reads as zero. The program counter is 23 bits wide, but the least significant bit is always 0, so there are 22 modifiable bits.The destination and one of the sources also support addressing modes, allowing the operand to be in memory pointed to by a W register.Today, starting at 28 pin in small QFN packages up to high performance devices with Ethernet, CAN and USB OTG, full family range of mid-range 32-bit microcontrollers are available.Their key advantage is to support the 16bits instructions of MIPS making program size much more compact (about 40)Special-purpose control registers for on-chip hardware resources are also mapped into the data space. The addressability of memory varies depending on device series, and all PIC devices have some banking mechanism to extend addressing to additional memory. Later series of devices feature move instructions, which can cover the whole addressable space, independent of the selected bank. In earlier devices, any register move had to be achieved through the accumulator. A register number is written to the FSR, after which reads from or writes to INDF will actually be from or to the register pointed to by FSR. This also allows FSR to be treated almost like a stack pointer (SP).In general, there is no provision for storing code in external memory due to the lack of an external memory interface.However, the unit of addressability of the code space is not generally the same as the data space. http://eco-region31.ru/elves-war-fighting-manual

For example, PICs in the baseline (PIC12) and mid-range (PIC16) families have program memory addressable in the same wordsize as the instruction width, i.e. 12 or 14 bits respectively. In contrast, in the PIC18 series, the program memory is addressed in 8-bit increments (bytes), which differs from the instruction width of 16 bits.The hardware stack is not software-accessible on earlier devices, but this changed with the 18 series devices.The instruction set includes instructions to perform a variety of operations on registers directly, the accumulator and a literal constant or the accumulator and a register, as well as for conditional execution, and program branching.To load a constant, it is necessary to load it into W before it can be moved into another register.Because cores before PIC18 had only unconditional branch instructions, conditional jumps are implemented by a conditional skip (with the opposite condition) followed by an unconditional branch. Skips are also of utility for conditional execution of any immediate single following instruction. It is possible to skip skip instructions.The result can be written to either the Working register (e.g. addwf reg,w ). or the selected register (e.g. addwf reg,f ). The latter are used to perform conditional branches.The Harvard architecture, in which instructions and data come from separate sources, simplifies timing and microcircuit design greatly, and this benefits clock speed, price, and power consumption.Such lookups take one instruction and two instruction cycles. Many functions can be modeled in this way. Optimization is facilitated by the relatively large program space of the PIC (e.g. 4096 ? 14-bit words on the 16F690) and by the design of the instruction set, which allows embedded constants.External interrupts have to be synchronized with the four-clock instruction cycle, otherwise there can be a one instruction cycle jitter. Internal interrupts are already synchronized. http://directealgerie.com/images/capresso-c1000-manual.pdf

The constant interrupt latency allows PICs to achieve interrupt-driven low-jitter timing sequences. An example of this is a video sync pulse generator. This is no longer true in the newest PIC models, because they have a synchronous interrupt latency of three or four cycles.For example, on PIC16, CALL and GOTO have 11 bits of addressing, so the page size is 2048 instruction words. For computed GOTOs, where you add to PCL, the page size is 256 instruction words. In both cases, the upper address bits are provided by the PCLATH register. This register must be changed every time control transfers between pages.Judicious use of simple macros can increase the readability of PIC assembly language. It has macro instructions like mov b, a (move the data from address a to address b ) and add b, a (add data from address a to data in address b ). It also hides the skip instructions by providing three-operand branch macro instructions, such as cjne a, b, dest (compare a with b and jump to dest if they are not equal).Likewise, the original 12-bit instruction set of the PIC1650 and its direct descendants has been superseded by 14-bit and 16-bit instruction sets. Microchip still sells OTP (one-time-programmable) and windowed (UV-erasable) versions of some of its EPROM based PICs for legacy support or volume orders. The Microchip website lists PICs that are not electrically erasable as OTP. UV erasable windowed versions of these chips can be ordered.Conversely, a C generally means it can only be erased by exposing the die to ultraviolet light (which is only possible if a windowed package style is used). An exception to this rule is the PIC16C84 which uses EEPROM and is therefore electrically erasable.They also sell C compilers for the PIC10, PIC12, PIC16, PIC18, PIC24, PIC32 and dsPIC, which integrate cleanly with MPLAB X. Free versions of the C compilers are also available with all features.

A fully featured compiler for the PICBASIC language to program PIC microcontrollers is available from meLabs, Inc. Mikroelektronika offers PIC compilers in C, BASIC and Pascal programming languages.It exists in numerous versions from a free demonstration to a more complete professional edition.It connects by RS 232 cable to a PC compatible running development software.Demo boards are available with a small bootloader factory programmed that can be used to load user programs over an interface such as RS-232 or USB, thus obviating the need for a programmer device.After programming the bootloader onto the PIC, the user can then reprogram the device using RS232 or USB, in conjunction with specialized computer software.Many of these complex programmers use a pre-programmed PIC themselves to send the programming commands to the PIC that is to be programmed. The intelligent type of programmer is needed to program earlier PIC models (mostly EPROM type) which do not support in-circuit programming.Some are simple designs which require a PC to do the low-level programming signalling (these typically connect to the serial or parallel port and consist of a few simple components), while others have the programming logic built into them (these typically use a serial or USB connection, are usually faster, and are often built using PICs themselves for control).MPLAB ICD and MPLAB REAL ICE debuggers can communicate with this interface using the ICSP interface.Some larger chips also have no debug module. To debug these devices, a special -ICD version of the chip mounted on a daughter board which provides dedicated ports is required. Some of these debug chips are able to operate as more than one type of chip by the use of selectable jumpers on the daughter board. This allows broadly identical architectures that do not feature all the on chip peripheral devices to be replaced by a single -ICD chip.It is currently discontinued.

Designed to be architecturally similar to the PIC microcontrollers used in the original versions of the BASIC Stamp, SX microcontrollers replaced the PIC in several subsequent versions of that product.They include up to 4096 12-bit words of flash memory and up to 262 bytes of random access memory, an eight bit counter and other support logic. Other interfaces are relatively easy to write, and existing modules can be modified to get new features.Retrieved 2011-08-02. CS1 maint: archived copy as title ( link ) Retrieved 2011-08-02.
