Description

The PIC16F84A-04/P is one member of the PIC16F84A series.It has the following features including (1)All instructions single cycle except for program branches which are two-cycle;(2)1024 words of program memory;(3)15 special function hardware registers;(4)Direct, indirect and relative addressing modes;(5)1000 erase/write cycles Enhanced Flash program memory;(6)Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation.

This document contains device-specific information for the operation of the PIC16F84A-04/P device. Additional information may be found in the PICmicro™ Mid-Range Reference Manual, (DS33023), which may be downloaded from the Microchip website. The Reference Manual should be considered a complementary document to this data sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules.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.

About PIC16F84A-04/P, Portions of data memory are banked. This is for both the SFR area and the GPR area. The GPR area is banked to allow greater than 116 bytes of general purpose RAM. The banked areas of the SFR are for the registers that control the peripheral functions. Banking requires the use of control bits for bank selection.These control bits are located in the STATUS Register.Midrange devices have an 8 level deep x 13-bit wide hardware stack. The stack space is not part of either program or data space and the stack pointer is not readable or writable. The PC is PUSHed onto the stack when a CALL instruction is executed or an interrupt causes a branch. The stack is POPed in the event of a RETURN, RETLW or a RETFIE instruction execution. PCLATH is not modified when the stack is PUSHed or POPed.
