Datasheet

1. General description
The LPC12D27 are ARM Cortex-M0 based microcontrollers 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 LPC12D27 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 auto-increment addressing.
The LPC12D27 operate at CPU frequencies of up to 45 MHz and include 128 kB of flash
memory and 8 kB of data memory.
The peripheral complement of the LPC1227 microcontroller includes a micro DMA
controller, one Fast-mode Plus I
2
C interface, one SSP interface, two UARTs, four general
purpose timers, a 10-bit ADC, two comparators, and up to 40 general purpose I/O pins.
Remark: For a functional description of the LPC1227 microcontroller see the LPC122x
data sheet. For a detailed description of the LCD driver see the PCF8576D data sheet.
