LPC12D27FBD100/301

LPC12Dxx microcontrollers are a compelling solution for safety-critical, high-reliability industrial automation and white good applications requiring support for segment LCD display. They are rated 'high immunity' based on the Electrical Fast Transient (EFT) test conducted by Langer EMV-Technik GmbH per IEC 61697-1 recommendations and are IEC 60730 Class B-certified. LPC12Dxx microcontrollers include on-chip support for a segment LCD controller capable of driving any static or multiplexed LCD containing up to 160 segments (40 segments x 4 backplanes). They extend the feature set of LPC11Dxx microcontrollers with up to 128 kB of Flash and analog peripherals such as dual comparators with 32 levels of voltage reference, edge and level detection, and an output feedback loop.
