COMPONENT DESCRIPTION
• MT8870• PIC 16F887A• USART• INTER INTEGRATED CIRCUIT
![Page 13: Mobile t fa_for_atm_1](https://reader036.fdocuments.in/reader036/viewer/2022062319/55858193d8b42ab2148b4a00/html5/thumbnails/13.jpg)
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
![Page 20: Mobile t fa_for_atm_1](https://reader036.fdocuments.in/reader036/viewer/2022062319/55858193d8b42ab2148b4a00/html5/thumbnails/20.jpg)
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.

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.
![Page 25: Mobile t fa_for_atm_1](https://reader036.fdocuments.in/reader036/viewer/2022062319/55858193d8b42ab2148b4a00/html5/thumbnails/25.jpg)
Baud Rate Generator (BRG)
• It support both asynchronous and synchronous mode.
• SPBRG • Baud rate formula
