Induction Cooker Flash MCU
The device 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 operational amplifier and six comparators, five of which are used for Over Voltage Protection function. Easy communication with the outside world is provided using the internal I2C interface function. 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. In addition, the device can generate two types voltage slew-rate (Quick Slew-Rate or Slow Slew-Rate) by the integrated Level Shifter to drive IGBT gate. Users can control the IGBT driving pulse wave time and the voltage slew-rate to achieve the induction cooker low power continuous heating function and reduce EMI interference.
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 device contains all the level shifting circuitry required match the high voltage and high current requirements of IGBT devices. To prevent malfunctions and possible system damage, an internal voltage detector monitors the system voltage level to determine if the level shifter can be enabled or not.
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.
