Various older (EPROM) PIC microcontrollers. The original PIC was intended to be used with General Instrument's new CP1600 16-bit central processing unit (CPU). In order to fit 16-bit data and address buses into a then-standard 40-pin dual inline package (DIP) chip, the two buses shared the same set of 16 connection pins. In order to communicate ...
The PIC instruction set refers to 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.
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 PIC16C84, PIC16F84 and PIC16F84A are 8-bit microcontrollers of which the PIC16C84 was the first introduced in 1993 [citation needed] and hailed [by whom?] as the first PIC microcontroller to feature a serial programming algorithm and EEPROM memory. [citation needed] It is a member of the PIC family of controllers, produced by Microchip ...
While Arm is a fabless semiconductor company (it does not manufacture or sell its own chips), it licenses the ARM architecture family design to a variety of companies. Those companies in turn sell billions of ARM-based chips per year—12 billion ARM-based chips shipped in 2014, [1] about 24 billion ARM-based chips shipped in 2020, [2] some of those are popular chips in their own right.
Closeup of an Intel 8259A IRQ chip from a PC XT. Pinout. The Intel 8259 is a programmable interrupt controller (PIC) designed for the Intel 8085 and 8086 microprocessors. The initial part was 8259, a later A suffix version was upward compatible and usable with the 8086 or 8088 processor.
PIC: Amicus18 is an embedded system platform based on PIC architecture (18F25K20). Can be programmed with any programming language, though the Amicus IDE is free and complete. Cortino [248] ARM STM32: Development system for a 32-bit ARM Cortex-M3-based microcontroller. Pinguino [249] PIC
Some microcontroller devices (e.g., Microchip dsPIC33 family) incorporate internal signal routing circuitry that allows GPIOs to be programmatically mapped to device pins. Field-programmable gate arrays (FPGA) extend this ability by allowing GPIO pin mapping, instantiation and architecture to be programmatically controlled.
