Introduction

The 78K0R lineup is based on a 16-bit CISC core and has an instruction set that is upward compatible with NEC Electronics’ popular 8-bit 78K0 core. These microcontrollers are designed to meet the ever-increasing demand for low power consumption and high performance in battery-powered applications.

• Industry’s lowest power consumption of 1.5 mW per DMIPS
• True real-time clock with full calendar and alarm functions
• Innovative peripherals such as a serial array unit and timer array unit that provide flexibility for a wide range of embedded applications
