Datasheet

1. General description
The LPC11D14 is a ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for
8/16-bit microcontroller applications, offering performance, low power, simple instruction
set and memory addressing together with reduced code size compared to existing 8/16-bit
architectures.
The LPC11D14 is a dual-chip module consisting of a LPC1114 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 LPC11D14 operates at CPU frequencies of up to 50 MHz.
The peripheral complement of the LPC11D14 includes 32 kB of flash memory, 8 kB of
data memory, one Fast-mode Plus I
2
C-bus interface, one RS-485/EIA-485 UART, up to
two SPI interfaces with SSP features, four general purpose counter/timers, a 10-bit ADC,
and up to 42 general purpose I/O pins.
Remark: For a functional description of the LPC1114 microcontroller see the
LPC1111/12/13/14 data sheet. For a detailed description of the LCD driver see the
PCF8576D data sheet. Both data sheets are available on the NXP web site.
