Pic16873 current models use flash memory for program storage, and newer models allow the PIC to reprogram itself. This is no longer true in the newest PIC models, because they have a synchronous interrupt latency of three or four cycles. These devices feature a bit wide code memory, and an improved 8-level deep call stack.

Generally the first 7 to 9 bytes of the register file are special-purpose registers, and the remaining bytes are general purpose RAM. Datasheef binary representations of the machine instructions vary by family and are shown in PIC instruction listings.

Hardware support for a general-purpose parameter stack was lacking in early series, but this greatly improved in the 18 series, making the 18 series architecture more friendly to high-level language compilers.

In contrast to earlier devices, which were more often than not programmed in assembly, C has become the predominant development language. There are some “enhanced baseline” variants with interrupt support and a four-level call stack.

Devices called ” programmers ” are traditionally used pic16g873 get program code into the target PIC.

Microchip delivered this 12 billionth MCU approximately 10 months after delivering its 11 billionth. Within a series, there are still many device variants depending on what hardware resources the chip features:.


Note that a CALL instruction only includes 8 bits of address, and may only specify addresses in the first half of each word page. A complex set of interrupts are available. Optimization satasheet facilitated by the relatively large program space of the PIC e.

PIC microcontrollers

Data memory is 8-bit, bit, and, in latest models, bit wide. Judicious use of simple macros can increase the readability of PIC assembly language. 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 registeras well as for conditional execution, and program branching.

Baseline devices are available in pic16f73 to pin packages. Pointers are implemented using a register pair: Archived copy as title CS1 Russian-language sources ru Puc16f873 articles with unsourced statements Articles with unsourced statements from August Articles containing Russian-language text Commons category link is on Wikidata Articles prone to spam from September Articles with Curlie links.

InMicrochip introduced the dsPIC series of chips, [10] which entered mass production in late The addressability of memory varies depending on device series, and all PIC devices have some banking mechanism to extend addressing to additional memory. Retrieved 13 October On the older cores, all register moves datqsheet to pass through W, but this changed on the “high-end” cores.

Archived from the original PDF on 27 October Retrieved 2 August Software can access ROM in bit words, where even words hold the least significant 16 bits of each instruction, and odd words hold the most significant 8 bits. 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.


The PIC instruction set is suited to implementation of fast lookup tables in the program space. In order to be clear, the program memory capacity is usually stated in number of single-word instructions, rather than in bytes. In more advanced PIC18 devices, an “extended mode” is available which makes the addressing even more favorable to compiled code:. To debug these devices, a special -ICD version of the chip mounted on a daughter board which provides dedicated ports is required.


Likewise, the original bit instruction set of the PIC and its direct descendants has been superseded by bit and bit instruction sets. The 18 series implemented shadow registers, registers which save several important registers during an interrupt, providing hardware support for automatically saving processor state when servicing interrupts.

Wikibooks has a book on the topic of: An open source project by Serge Vakulenko adapts 2. It is currently discontinued. Retrieved September 16, The 17 series never became popular and has been superseded by the PIC18 architecture however, see clones below. PIC24 devices are designed as general purpose microcontrollers.

PIC17 devices were produced in packages from 40 to 68 pins. Instruction ROM is 24 bits wide. Although still similar to earlier PIC architectures, there are significant enhancements: This register must be changed every time control transfers between pages. An example of this is a video sync pulse generator.
