HT46R4A 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 designed especially for applications that interface directly to analog signals, such as those from sensors. The devices include an integrated multi-channel Analog to Digital Converter in addition to 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.
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, industrial 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.
