Recover MCU PIC16F874 Code from both eeprom and flash need to know also its peripheral features of it:

Peripheral Features:

· Timer0: 8-bit timer/counter with 8-bit prescaler

· Timer1: 16-bit timer/counter with prescaler, can be incremented during SLEEP via external crystal/clock

· Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler

· Two Capture, Compare, PWM modules

– Capture is 16-bit, max. resolution is 12.5 ns

– Compare is 16-bit, max. resolution is 200 ns

– PWM max. resolution is 10-bit

· 10-bit multi-channel Analog-to-Digital converter

· Synchronous Serial Port (SSP) with SPI (Master mode) and I2C (Master/Slave) when Crack MCU

· Universal Synchronous Asynchronous Receiver Transmitter (USART/SCI) with 9-bit address detection

· Parallel Slave Port (PSP) 8-bits wide, with external RD, WR and CS controls (40/44-pin only)

· Brown-out detection circuitry for Brown-out Reset (BOR)

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. 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.

DEVICE OVERVIEW

– PWM max. resolution is 10-bit

· 10-bit multi-channel Analog-to-Digital converter

· Synchronous Serial Port (SSP) with SPI (Master mode) and I2C (Master/Slave)

· Universal Synchronous Asynchronous Receiver Transmitter (USART/SCI) with 9-bit address detection in the process of Recovery MICROCONTROLLER PIC16F872 Program

· Parallel Slave Port (PSP) 8-bits wide, with external RD, WR and CS controls (40/44-pin only)

· Brown-out detection circuitry for Brown-out Reset (BOR)

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.

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.
