HT82B42R/HT82B42RE -- I/O MCU with USB
Interface General 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.
