1 / 60 page  HT46R4A Cost-Effective A/D Type 8-Bit MCU Rev. 1.00 1 November 28, 2007 General Description The HT46R4A is a device from the Cost-Effective A/D Type Series of MCUs. As an 8-bit high performance RISC architecture microcontroller, the device is de- signed especially for applications that interface directly to analog signals, such as those from sensors. The de- vices include an integrated multi-channel Analog to Dig- ital Converter in addition to two Pulse Width Modulation outputs. The usual Holtek MCU features such as power down and wake-up functions, oscillator options, programma- ble frequency divider, etc. combine to ensure user appli- cations require a minimum of external components. The benefits of integrated A/D and PWM functions, in addition to 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 sensor signal processing, motor driving, indus- trial control, consumer products, subsystem controllers, etc. As is the case with all Holtek microcontroller devices, the HT46R4A is fully supported by a full suite of profesional hardware and software tools, containing comprehensive features to ensure user applications are designed and debugged in as short a time as possible.
