HT82B60R -- I/O MCU with USB Interface

General Description

The HT82B60R is a high performance, RISC architecture microcontroller device specifically designed for multiple I/O control product applications.

The advantages of low power consumption, I/O flexibility, timer functions, integrated USB interface, serial interfaces, LCD drive capability, power down and wake-up functions, watchdog timer etc, make the device extremely suitable for use in computer peripheral product applications as well as many other applications such as industrial control, consumer products, subsystem controllers, etc.

These wide range of functions, together with a fully integrated 6MHz or 12MHz oscillator, ensure that products can be implemented with a minimum of external components and smaller circuit board areas, providing users with the benefits of lower overall product costs.
