General Description
The HT82B60R is a high performance, RISC architec-
ture 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, serial in-
terfaces, LCD drive capability, power down and
wake-up functions, watchdog timer etc, make the de-
vice extremely suitable for use in computer peripheral
product applications as well as many other applications
such as industrial control, consumer products, subsys-
tem controllers, etc.
These wide range of functions, together with a fully inte-
grated 6MHz or 12MHz oscillator, ensure that products
can be implemented with a minimum of external compo-
nents and smaller circuit board areas, providing users
with the benefits of lower overall product costs.
