18-pin Flash/EEPROM 8-Bit Microcontrollers
A newer device is available.
Please consider PIC16F84A. This powerful (400 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS ROM/EEPROM-based 8-bit microcontroller packs Microchip’s powerful PIC architecture into an 18-pin package. Easily adapted for automotive, industrial, appliances, and low power remote sensors, electronic locks and security applications.
