8-BIT MCU WITH 24K ROM, EEPROM,ADC,PWM/BRM DACs,SYNC PROCESSOR,EWPCC,TIMER AND DDC INTERFACE

INTRODUCTION The ST7272 HCMOS Microcontroller Unit is a member of the ST7 family of Microcontroller. The device is based on an industry-standard 8-bit core and features an enhanced instruction set. Oscillator frequency can be as high as 8MHz, however, thanks to the fully static design, operation

HIGH PERFORMANCE MOTOR SPEED REGULATOR

DESCRIPTION TDA7272A are high performance motor speed controller for small power DC motors as used in cassette players. Using the motor as a digital tachogenerator itself the performance of true tacho controlled systems is reached. A dual loop control circuit provides long term stability and fa
