General Description
The HT47R10A-1/HT47C10-1 are 8-bit, high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for applications that interface directly
to analog signals, such as those from sensors. The
mask version HT47C10-1 device is fully pin and func-
tionally compatible with the HT47R10A-1, OTP version
device.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, RC type A/D Converter, LCD driver,
Power Down and wake-up functions, enhance the ver-
satility 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.
