NEC Lx3 Microcontrollers

NEC’s 78K0/Lx3 series of 8-bit microcontrollers (MCUs) feature liquid crystal display (LCD) controllers, drivers on-chip, and low power consumption. The devices are ideal for consumer electronics with LCD readouts and strict power consumption requirements, such as home health appliances including scales, blood pressure monitors, and blood glucose meters; HVAC and industrial systems including utility meters; and household appliances such as coffee makers and rice cookers.

The Lx3 devices have a newly optimized circuit design that cuts standby power consumption by approximately 50 percent (compared to 78K0/Lx2 MCUs), down to just 2.3 microamperes (µA). A 16-bit A/D converter offers a 64-fold improvement in resolution over the previous generation of devices. Additionally, an increase in the number of common signal ports from four to eight now enables support for up to 288 display segments, up from 160 for the previous Lx2 devices. The improvement in features helps support manufacturers of LCD applications create higher resolution products, or alternately, create the same resolution with fewer segment ports. The new MCUs are available in 76 configurations, with 8 kilobytes (KB) to 60 KB of embedded flash memory, in pin counts ranging from 48 to 80.

NEC Electronics’ 78K0/Lx3 MCUs use 0.15-micron process technology and SuperFlash(R) technology licensed from Silicon Storage Technology, Inc.

Samples of the 78K0/Lx3 devices is available now. Pricing varies according to device specifications. For example, the 80-pin 78K0/LF3 device with 60KB flash memory is priced at $6 for 1,000-lot quantities. Monthly production is expected to reach approximately 100,000 units by the third quarter of 2008.
