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.
