please send circuit .I am in emergency condition please.

What is thread please replay the message and please send the diagram

pic16f877a microcontroller interfacing apr9600

This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into an 40- or 44-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.

VOICE CHIP APR9600 INTERFACING WITH 8051 MICRO CONTROLLER is mainly used in mobile communication for recording and replaying the voice message according to the situation need. This application uses APR9600 voice chip for storing and playing recorded video which is integrated with 8051 micro controller.
