HT46R14A General Description


The HT46R14A is an 8-bit, high performance, RISC archite cturemicr ocontrollerdevices specifically designed for A/D tions that in terface directly toanalog signals, such as those from sensors.

The advantages of low power consumption, I/O flexibility, program mable frequency divider, time tions,oscillatoroptions, multi-channel A/D Converter, HALT and wake-up functions, provide the device with thever satility tomeet there irements of wider ange of A/D application possibilities such as extern alanalog sensor signal processing.

With thein clusion of two compar at or sand a fully in tegrated  program mable pulse generator,  the deviceis parcularly suitable for useinproducts such as induction cooker sando ther home appliance application areas.
