Cortex-M0 MCUs first to include LCD drivers

Said to be the first Cortex M0 base MCUs to have LCD display drivers, the LPC11D00 and LPC12D00 series have a two chip package with a full PCF8576D LCD driver. They can drive displays with up to four backplanes and 40 segments, and can be cascaded with multiple segment LCD drivers to accommodate up to 2560 segments.

The 50 MHz devices support a wide LCD supply range from 2.5 to 6.5 V. The 11Dxx has up to 32 Kbytes of flash, while the 12Dxx features up to 128 Kbytes and also adds a CRC engine, DMA, and a real-time clock. Both devices feature a low 130 ua/MHz current requirement and have an 8-channel 10-bit A/D converter with ±1 bit differential and ±3 integral non-linearity maximum over the -40° to 85° operating range. (LPC11D00 from $1.53; LPC12D00 from $2.19 — available now.)
