PIC16F84A

This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS Flash/EEPROM-based 8-bit microcontroller packs Microchip’s powerful PIC® architecture into an 18-pin package. The same device can be used for prototyping and production and the end application can be easily updated without removing the device from the end product via the ICSP. Easily adapted for automotive, industrial, appliances low power remote sensors, electronic locks and security applications.
