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. There are two memory blocks in the PIC16F84A-04/P. These are the program memory and the data memory. Each block has its own bus, so that access to each block can occur during the same oscillator cycle.
