General Description

The HT45F23A is a Flash Memory Tinypower A/D type 8-bit high performance RISC architecture

microcontrollers, designed especially for applications that interface directly to analog signals.

The HT45F23A device has a higher gain bandwidth making it more suitable for higher frequency

applications.
