HT47R10A-1/HT47C10-1 -- R-F Type 8-Bit MCU

General Description

The HT47R10A-1/HT47C10-1 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for applications that interface directly to analog signals, such as those from sensors. The mask version HT47C10-1 device is fully pin and functionally compatible with the HT47R10A-1, OTP version device.

The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, RC type A/D Converter, LCD driver, Power Down and wake-up functions, enhance the versatility of these devices to suit a wide range of Resistor to Frequency application possibilities such as sensor signal processing, remote metering, industrial control, consumer products, subsystem controllers, etc.
