Features & Applications
The LPC1111FHN33/202,5 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 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 I2C-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.


  • System:
    • ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
    • ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
    • Serial Wire Debug
    • System tick timer
  • Memory:
    • 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.
  • Digital peripherals:
    • Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors. In addition, a configurable open-drain mode is supported on the LPC111x/102/202/302.
    • GPIO pins can be used as edge and level sensitive interrupt sources.
    • High-current output driver (20 mA) on one pin.
    • Programmable WatchDog Timer (WDT).
    • Programmable windowed WDT on LPC111x/102/202/302 only.
  • Analog peripherals:
    • 10-bit ADC with input multiplexing among 8 pins.
  • 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 package only).
    • I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode.
  • Clock generation:
    • 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock.
    • Crystal oscillator with an operating range of 1 MHz to 25 MHz.
