Compared to the company's previous 78K0/Lx2 MCUs, the Lx3 devices have a newly optimized circuit design that cuts standby power consumption by approximately 50 percent, down to just 2.3 microamperes (μA).
An 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.
