COMPONENT DESCRIPTION

• MT8870• PIC 16F887A• USART• INTER INTEGRATED CIRCUIT

INTRODUCTION

• DTMF stands for dual tone multiple frequency

• It is also known as touch-tone ,tone dialing.

• Each DTMF tone consists of two simultaneous tones

• Tones travel through the red and green wires, in a telephone.

ABOUT PIC

• PIC is stands for Peripheral Inter Face controller.

• PIC microcontroller is used for the controlling.

• 40 pin IC.• 33 I/O pins.• Operating voltage 5V.• Operating frequency 4-20 mhz.

REASON FOR USING PIC

• Harvard Architecture• Instruction Pipelining• RISC• Only 35 single word instruction

I2C

• I2C is Inter Integrated Circuit.• Communication between the EEPROM

cardand controller is I2C. • I2C can easily link multiple devices.• It provides good support for

communication.

I2C is a serial interface of only two signals.• SDA• SCL

I2C DATA TRANSFER.

USART• Universal Synchronous/Asynchronous

Receiver/Transmitter.• Serial data communication between PIC and terminal.• We used asynchronous mode.• half duplex

typically asynchronously 5 – 9 bits of data 2 or 3 framing bits

start bit 1 or 2 stop bits

0 or 1 parity bits

ASYNCHRONOUS MODE

• Baud rate generator.• Asynchronous transmitter.

Baud Rate Generator (BRG)

• It support both asynchronous and synchronous mode.

• SPBRG • Baud rate formula

ASYNCHRONOUS TRANSMITTER

ASYNCHRONOUS MASTER TRANSMISSION

COMPARISON

• SECURITY• USABILITY• ECONOMY
