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.
