HT82J30R/HT82J30A -- 16 Channel A/D MCU & SPI Interface

General Description

The HT82J30R/HT82J30A are 8-bit high performance, RISC architecture microcontroller devices specifically designed for A/D applications that interface directly to analog signals, such as those from sensors.

The mask version HT82J30A is fully pin and functionally compatible with the OTP version HT82J30R device.

The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, Watchdog timer, SPI interfaces, Power Down and wake-up functions, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sensor signal processing, 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.

The HT82J30A is under development and will be available soon.
