Proximity Sensing/Motor Driving Flash MCU

General Description

The device is an A/D Flash Memory type 8-bit high performance RISC architecture microcontroller

with integrated functions for Proximity Sensing/Motor Driving applications. Offering users the

convenience of Flash Memory multi-programming features, this device also includes a wide range

of functions and features. Other memory includes an area of RAM Data Memory as well as an area

of true EEPROM memory for storage of non-volatile data such as serial numbers, calibration data

etc.

Analog features include a multi-channel 12-bit A/D converter, two operational amplifiers,

a comparator and other circuits specifically designed for Proximity Sensing/Motor Driving

applications. With regard to internal timers, the device includes multiple and extremely flexible

Timer Modules providing functions for timing, pulse generation and PWM generation functions.

Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage

Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation

is maintained in hostile electrical environments. Other protection features also includes over current

protection function.

A full choice of internal low and high speed oscillator functions is provided including a fully

integrated system oscillator which requires no external components for its implementation. The

ability to operate and switch dynamically between a range of operating modes using different

clock sources gives users the ability to optimise microcontroller operation and minimise power

consumption.

This device contains a high voltage driver control circuit and a high voltage driver combination

circuit as well as high voltage power supply detection. The inclusion of ﬂexible I/O programming

features, Time-Base functions along with many other features ensure that the device will find

excellent use in various Proximity Sensing/Motor Driving products.
