NEC Electronics Introduces Eight New 8-bit Body Control MCUs with Industry’s Leading Low Standby Power Consumption for Low-End Automotive Applications


KAWASAKI, Japan, SANTA CLARA, Calif. (U.S.A.), DUESSELDORF, Germany, NEC Electronics (TSE: 6723) today announced the availability of eight new All FlashTM microcontrollers (MCUs) for safing microcontroller applications as well as low-end automotive systems, such as motor control and lighting control applications. The new offering includes three 16-pin MCUs (78K0/FY2-L), three 20-pin MCUs (78K0/FA2-L) and two 30-pin MCUs (78K0/FB2-L), featuring the industry’s leading low standby power consumption of 0.65 µA, and capable of responding to all temperature environments.
As the demand for increased functionality in automotive systems accelerates, the number of electronic-control units in automobiles rise as well. Manufacturers are under intense pressure to cut costs even as they deliver more sophisticated electronics modules, creating a need for components that can enable more precise motor control at lower development costs and lower power consumption. NEC Electronics’ new MCUs address these needs and will help to reduce the development burden on automotive manufacturers. Consumers also will benefit by having access to more sophisticated, eco-friendly products. Based on the same architecture as the company’s existing 8-bit 78K0 CPUs, the new MCUs are ideal as safing microcontroller for a larger main controller, and for electronic controls such as full-bridge control of high-density discharge (HID) lamps, full/half-bridge control of motor switching, switching control of solenoid drivers and pulse-width modulation (PWM) for LED dimming.

Primary features of the new body-control MCUs

* (1) Industry-leading low standby power consumption
By utilizing low power consumption technology accumulated through the 8-bit MCU development, NEC Electronics succeeded in achieving the industry’s leading low standby power consumption of 0.65 microamps (µA), while watchdog timer is operating. Furthermore, it enables low active power consumption of 220 µ per megahertz (MHz) during CPU operation. By using the internal 4 MHz oscillator system manufacturers can reduce both development and production costs.
* (2) Built-in LIN interface
The new MCUs all include a LIN interface, as well as up to 16 kilobytes (KB) of flash, doubling the company’s existing products and providing enough memory capacity for LIN network designs.
* (3) Extensive variety of peripheral functions including comparators and full/half-bridge control timers
NEC Electronics’ MCUs integrate a rich set of peripherals such as a PWM timer (with dead-time) for motors and solenoid actuators. Also included are comparators for instant control of timers, which provide the ability to detect overcurrent and overvoltage without the need of CPU intervention and enables system manufacturers to reduce external components and trim system development costs.
* (4) Software compatibility
System manufacturers of NEC Electronics’ previous versions of the 78K0/Kx2 and 78K0/Fx2 MCUs can maintain backward compatibility with the software and also develop LIN slave products utilizing the same architecture, contributing to a smooth transition and faster-time-to-market. The new MCUs also support EEPROM emulation using the flash memory to facilitate software development.

NEC Electronics believes these new MCUs will contribute to the increased body application functionality and cost-efficiency in automotive systems and aims to expand further its lineup of automotive body-control MCUs.

Pricing and availability

Samples of the new MCUs are currently available. Mass production is scheduled to begin in June 2010 and is expected to reach a monthly production of 300,000 units by June 2015. More information about NEC Electronics’ extensive MCU product offerings can be found at
