General Description
The HT82D40REW is 8-bit high performance, RISC ar-
chitecture microcontroller device specifically designed
for multiple I/O control product applications.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, integrated USB interface, Power
Down and wake-up functions, Watchdog timer etc,
make the devices extremely suitable for use in com-
puter peripheral product applications as well as many
other applications such as industrial control, consumer
products, subsystem controllers, etc.
