LPC1111/12/13/14
32-bit ARM Cortex-M0 microcontroller; up to 32 kB flash and
8 kB SRAM
Rev. 00.11 — 13 November 2009
Objective data sheet
1. General description
The LPC1111/12/13/14 are 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 LPC1111/12/13/14 operate at CPU frequencies of up to 50 MHz.
The peripheral complement of the LPC1111/12/13/14 includes up to 32 kB of flash
memory, up to 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
timers, a 10-bit ADC, and up to 42 general purpose I/O pins.
2. Features
ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or 8 kB (LPC1111) on-chip flash
programming memory.
8 kB, 4 kB, or 2 kB SRAM.
In-System Programming (ISP) and In-Application Programming (IAP) via on-chip
bootloader software.
Serial interfaces:
UART with fractional baud rate generation, internal FIFO, and RS-485 support.
Two SPI controllers with SSP features and with FIFO and multi-protocol
capabilities (second SPI on LQFP48 and PLCC44 packages only).
I 2 C-bus interface supporting full I 2 C-bus specification and Fast-mode Plus with a
data rate of 1 Mbit/s with multiple address recognition and monitor mode.
Other peripherals:
Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down
resistors.
Four general purpose timers/counters with a total of four capture inputs and 13
match outputs.
Programmable WatchDog Timer (WDT).
System tick timer.
Serial Wire Debug.
High-current output driver (20 mA) on one pin.
High-current sink drivers (20 mA) on two I 2 C-bus pins in Fast-mode Plus.
