HT45F0V/HT45F0VP -- TinyPowerTM A/D Flash Type 8-Bit MCU with EEPROM (限用产品)

General Description

The HT45F0V and HT45F0VP are TinyPowerTM A/D Flash Type MCU with EEPROM and are 8-bit high performance RISC architecture microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors. The device includes an integrated multi-channel Analog to Digital Converter in addition to a single Pulse Width Modulation output.

The usual Holtek MCU features such as power down and wake-up functions, oscillator options, programmable frequency divider, etc. combine to ensure user applications require a minimum of external components.

The benefits of integrated A/D and PWM functions, exceptionally low power consumption, high performance, I/O flexibility and low-cost, provides the device with the versatility to suit a wide range of application possibilities such as smoke detectors, sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc.
