Additional information may be found in the PICmicro™ Mid-Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip website before Read MCU PIC16F874 Eeprom. 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.

There are four devices (PIC16F874) covered by this datasheet. The PIC16F876/873 devices come in 28-pin packages and the PIC16F877/874 devices come in 40-pin packages. The Parallel Slave Port is not implemented on the 28-pin devices before Read MCU PIC16F874 Eeprom.

The following device block diagrams are sorted by pin number; 28-pin for Figure 1-1 and 40-pin for below Figure.

The 28-pin and 40-pin pinouts are listed in Table 1-1 and Table 1-2, respectively. There are three memory blocks in each of the PIC16F87X MCUs. The Program Memory and Data Memory have separate buses so that concurrent access can occur and is detailed in this section when Crack IC PIC12F629 Program. The EEPROM data memory block is detailed in Section 4.0.

Additional information on device memory may be found in the PICmicro Mid-Range Reference Manual, (DS33023). The PIC16F87X devices have a 13-bit program counter capable of addressing an 8K x 14 program memory space. The PIC16F877/876 devices have 8K x 14 words of FLASH program memory to faciliate the process of Break MCU Chip Microchip PIC16F876A, and the PIC16F873/874 devices have 4K x 14. Accessing a location above the physically implemented address will cause a wraparound. The RESET vector is at 0000h and the interrupt vector is at 0004h.
