Recover Microcontroller PIC16F874 Eeprom content needs to unlock mcu pic16f874 secured system and read the embedded firmware from mcu pic16f874 flash memory;

We can recover MICROCONTROLLER PIC16F874 Eeprom, please view the MICROCONTROLLER PIC16F874 Eeprom features for your reference:

This document contains device specific information

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 recover MICROCONTROLLER. The Reference Manual should be considered a complementary document to this data sheet, and is highly recommended recovering for a better understanding of the device architecture and operation of the peripheral modules.

There are four devices (PIC16F873, PIC16F874, PIC16F876 and PIC16F877) 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 avr atmel mcu firmware.

The following device block diagrams are sorted by pin number; 28-pin for Figure 1-1 and 40-pin for Figure 1-2.

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 MICROCONTROLLERs. The Program Memory and Data Memory have separate buses so that concurrent access can occur and is detailed in this section. 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 if recover MICROCONTROLLER. The PIC16F877/876 devices have 8K x 14 words of FLASH program memory, 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.
