General Description

The HT45F23 and HT45F43 are Flash Memory Tinypower A/D type 8-bit high performance RISC architecture microcontrollers. The HT45F43 device has low power internal operational amplifiers making it more suitable for power sensitive products. The HT45F23 device has a higher gain bandwidth product than the HT45F43 at the expense of power consumption making it more suitable for higher frequency applications.
