HT46R47 Datasheet PDF - Holtek

●General Description

●The Cost-Effective A/D Type MCU Devices are a series of 8-bit high performance RISC architecture

●microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors. All devices include an integrated multi-channel Analog to Digital Converter in addition to one or two Pulse Width Modulation outputs. 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.

●Features
