PIC16F84A-04/P

Product Summary

The PIC16F84A-04/P is an 8-Bit Microcontroller. The program memory contains 1K words, which translates to 1024 instructions, since each 14-bit program memory word is the same width as each device instruction. The data memory (RAM) contains 68 bytes. Data EEPROM is 64 bytes. The PIC16F84A-04/P has a 13-bit program counter capable of addressing an 8K * 14 program memory space. For the PIC16F84A-04/P, the first 1K x 14 (0000h-03FFh) are physically implemented. Accessing a location above the physically implemented address will cause a wraparound.
