78K0/Dx2 MCUs

NEC Electronics has released the 78K0/Dx2 product series of flash microcontrollers that includes a wide range of peripherals with either 80 or 64 pins and memory capacity ranging from 60- down to 24Kbyte.

Automotive sales in the emerging markets, including China, India and Brazil have been showing strong growth buoyed by their continuous economic growth. NEC Electronics is offering these new products to support the manufacturers of small-cars and motorcycles as they capture accelerating consumer demand.

To further address the customer demand, NEC revised the peripherals of the dashboard meters and expects this new line of MCUs will promote its expansion in China and India.

The new devices provide a rich set of new peripherals such as stepper motor driver/controller and increased the total number of timer channels from six to nine. Also included are LCD driver/controller, a CAN interface, and a sound generator all in a single chip, enabling system manufacturers to reduce external components and trim system development costs.

The extensive lineup of MCUs differs by flash memory capacity, RAM capacity, necessity of CAN interface, number of stepping motor driver/controller channels and LCD drive/display capability. Designers can choose the optimum configuration for their applications.

Samples of the new MCUs are currently available. Mass production of these new products is scheduled to begin in October 2010 and is expected to reach a monthly production of 100,000 units by October 2013.
