HT45R2K-C中文资料Dual Slope 16K/8K/4K ASSP MCU for Body Fat Scale数据手册Holtek规格书

描述 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.
