Microchip PIC16F84 Microcontroller DIP 18 Pin
Description
Description
The PIC16F84A from Microchip Technology is a low-cost, high-performance, 8-bit, fully static, Flash-based CMOS microcontroller. It employs a RISC architecture with only 35 single-word/single-cycle instructions. All instructions are single cycle except for program branches which take two cycles. The PIC16F84A delivers performance an order of magnitude higher than its competitors in the same price category. The easy-to-use and easy-to-remember instruction set reduces development time significantly.
The PIC16F84A products are equipped with special features that reduce system cost and power requirements. There are 4 oscillator configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator. Powersaving Sleep mode, Watchdog Timer and code protection features improve system cost, power and reliability.
