78K Family

Overview

The extensive 78K series lineup provides the ideal product for almost any application. For a compact, low-power MCU, choose one of the products in the 8-bit 78K0 and 78K0S series, and for a controller that offers the performance of a 32-bit MCU but consumes the power of an 8-bit one, look no further than the 16-bit 78K0R.
