The PIC instruction set is the set of instructions that Microchip Technology PIC or dsPIC microcontroller supports. The instructions are usually programmed into the Flash memory of the processor, and automatically executed by the microcontroller on startup. PICmicro chips have a Harvard architecture and instruction words have unusual sizes ...
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. Parallax's SX are 8-bit RISC microcontrollers, using a 12-bit instruction word, which run fast at 75 MHz (75 MIPS).
In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQs) coming from multiple different sources (like external I/O devices) which may occur simultaneously. [1]
The PIC16x84 microcontroller is a member of Microchip's 14-bit series (the instruction word size is 14 bits for all instructions), making the '84 a good development prototype for other similar but cheaper one-time-programmable 14-bit devices.
The intent of PICKitPlus is to facilitate the programming of any 8-bit PIC microcontroller using the PICkit™ 2 and PICkit™ 3 (ICSP) In-Circuit Debuggers/Programmers. The software extends the life of the existing PICkit2 and PICkit3 hardware devices by allowing them to work with the newer 8-bit PIC microcontrollers. The capabilities include:
PICAXE 20M2. PICAXE is a microcontroller system based on a range of Microchip PIC microcontrollers.PICAXE devices are Microchip PIC devices with pre-programmed firmware that enables bootloading of code directly from a PC, simplifying hobbyist embedded development (not unlike the Arduino and Parallax BASIC Stamp systems).
An example of this is the CLRWDT (clear watchdog timer) instruction found in the instruction set of some PIC microcontrollers. In computers that are running operating systems , electronic watchdog restarts are usually invoked through a device driver .
PIC microcontrollers PIC24 microcontroller. Since 2013, Microchip has shipped over 1 billion PIC microcontrollers per year, growing every year. [5] Microchip produces microcontrollers with three very different architectures: 8-bit (8-bit data bus) PICmicro, with a single accumulator (8 bits): PIC10 and PIC12: 12-bit instruction words
