WHAT ARE MICRO CONTROLLERS ?

Annmark Technologies

MICRO CONTROLLERS A Complete Microcomputer On Chip Microprocessor-ROM-RAM & I/O

* RISC Processors Concept Simplified The Decoder Design More Room For Embedded Peripherals * Microprocessors Clubbed With Peripherals Code & Data Memory Timers/counters UART(serial Ports) ADC & DAC ,PWM Variety Of Choices Annmark Technologies

What do the Micro controllers contain ?

Annmark Technologies

Micro controllers contain ROM - MASK , OTP ,UVEPROM, FLASH RAM - LOTS OF REGISTERS OR SOME RAM 32BYTES TO 1KBYTE TIMERS/COUNTERS/CAPTURE TIMER I/O PORTS UART , SPI , ISP , I2C BOOLEAN PROCESSORS Annmark Technologies

Micro controllers contain VARIATIONS USING THE SAME CORE – ETHERNET CONTROOLER DTMF ENCODER/DECODERS WIRELESS TRANSCIEVERS HUMAN INTERFACE DEVICES irDA , ENCRYPTION & DECRYPTION FIRMWARE(DES) Annmark Technologies

PROGRAMMING THE MICRO CONTROLLERS

Annmark Technologies

In System Programming-1 • Programming any proms needs a Programmer device (PD) • Device needs to be physically removed from its socket • Addition of control circuits in chip replace need for PD • External Programming voltage is needed • Address/data sent to device through interface Annmark Technologies

In System Programming-2 programming interface

MCU’S HAVE PROGRAMMER FIRMWARE IN ROM INTERFACES USED FOR ISP SPI- SERIAL PROGAMMING INTERFACE data-in data-out reset clock I2C- INTER IC INTERFACE sdata sclock RS 232 rx

tx

Annmark Technologies

In System Programming-3 programming software

THE MCU SOURCE PROVIDES THE S/W ALGORITHMS ARE IN DATA SHEETS FOR SELF CODING SPECIAL BIT SELECTS BOOT FROM RESET VECTOR BOOT FROM FIRMWARE ERASE IS THROUGH A DEDICATED PIN AND RESET Annmark Technologies

In Application Programming-1 The CPU has read while write capability Able to program or reprogram the Flash memory block SPI , UART or two wire interface are used Programmable even while application code is executing

Annmark Technologies

In Application Programming-2 The flash memory is divided – a boot and application code block Made up of sectors containing 128 bytes Small sector size reduces programming timefor code patches, updates and changes Lock bits protect code in both blocks avoiding unauthorised access & Accidental programming Annmark Technologies
