HT45F0058

Induction Cooker Flash MCU

General Information

The HT45F0058 is a Flash Memory type 8-bit high performance RISC architecture microcontroller especially designed for induction cooker applications.

For memory features, the Flash Memory offers users the convenience of multi-programming 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, an OPAMP and multiple comparators 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, an Over Voltage Protection, a Peripheral Clock Output along with many other features ensure that the device will find excellent use in induction cooker applications.
