HT45F0004

Induction Cooker Flash MCU

General Information

(HT45F0004 16/20DIP Package Restricted Products. Notification Date : 2021/09/30 Effective Date : 2021/12/30)

The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller designed for the A/D applications that interface directly to analog signals, such as those from sensors. The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, multi-channel A/D converter, power down and wake-up functions enhance the versatility of this device to suit for a wide range of A/D application possibilities such as sensor signal processing. The device also provides four comparators, an operational amplifier and a programmable pulse generator – PPG, hence it is particularly for use in products such as induction cooker and home appliances.
