# PIC16F84A-20I/P (Component)
## Description
PIC PIC® 16F Microcontroller IC 8-Bit 20MHz 1.75KB (1K x 14) FLASH 18-PDIP
The Microchip PIC16F84A-20I/P features 1K × 14 words of Flash program memory, 68 bytes of RAM, and 64 bytes of EEPROM data memory. It operates with a supply voltage range of 2.0 V to 5.5 V and supports an external clock frequency of up to 20 MHz. The device provides 13 bidirectional I/O pins and includes a Timer0 8-bit timer/counter with prescaler, as well as interrupt capability. It uses a 14-bit instruction set architecture and integrates serial programming support. The MCU is supplied in an 18-pin PDIP package and is specified for an industrial temperature range of −40°C to +85°C.
