General Description

The HT82B40R and HT82B40A are 8-bit high perfor-

mance, RISC architecture microcontroller devices spe-

cifically designed for multiple I/O control product

applications.

The advantages of low power consumption, I/O flexibility,

timer functions, integrated USB interface, Power Down

and wake-up functions, Watchdog timer etc, make the
