HT82B42R中文资料I/O MCU with USB Interface数据手册Holtek规格书

描述 Description

?

The HT82B42R is 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. In addition, the HT82B42RE is embedded with an EEPROM device.

The advantages of low power consumption, I/O flexibility, timer functions, integrated USB interface, serial SPI interface, Power Down and wake-up functions, Watchdog timer etc., make the devices extremely suitable for use in computer peripheral product applications as well as many other applications such as industrial control, consumer products, subsystem controllers, etc.

EEPROM memory is incorporated into the HT82B42RE, which is useful for applications that require an area of non-volatile memory, perhaps to store information such as calibration parameters, part numbers etc.. Most features are common to the HT82B42R, however, they differ in the provision of an EEPROM.
