The LPC12D27FBD100/301 is an Arm Cortex-M0 based microcontroller for embedded applications featuring a high level of integration and low power consumption. The Arm Cortex-M0 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The LPC12D27FBD100/301 is a dual-chip module consisting of a LPC1227 single-chip microcontroller combined with a PCF8576D Universal LCD driver in a low-cost 100-pin package. The LCD driver provides 40 segments and supports from one to four backplanes. Display overhead is minimized by an on-chip display RAM with autoincrement addressing.
