HT45R1005

Induction Cooker OTP MCU

General Information

The device is an OTP type 8-bit high performance RISC architecture microcontroller, especially designed for induction cooker applications.

Analog features include a multi-channel 12-bit A/D converter, an operational amplifier and five comparators, four of which are used for Over Voltage Protection 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.

The device also includes fully integrated high and low speed oscillators which require no external components for their 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.

The inclusion of flexible I/O programming features, Timers, a Programmable Pulse Generator, a Peripheral Clock Output along with many other features ensure that the device will find excellent use in induction cooker applications.
