General Description
The HT45R2K-C is an 8-bit high performance, RISC architecture microcontroller device, which
with its A/D Converter and LCD driver, can directly interface to analog signals and to LCD panels.
The device includes a range of other features such as low power consumption, I/O flexibility, timer
functions, oscillator options, dual slope A/D convertor, HALT and wake-up functions, watchdog
timer, vibration sensor etc. However as the device includes all the circuitry associated with body
fat measurement the device is especially suitable for this specific application area, being able to
significantly reduce the need for the usual external components.
