HT82J31A -- 16 Channel A/D MCU with SPI Interface

General Description

The device is an 8-bit high performance, RISC architecture microcontroller devices specifically designed for the multiple I/O control product applications.

The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, SPI interface, Power Down and wake-up functions, Watchdog timer, motor driving, industrial control, consumer products, subsystem controllers, etc. With the provision of dual SPI interfaces the devices are especially suitable for Joystick Encoder applications.
