The LPC11E3x 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 LPC11E3x operate at CPU frequencies of up to 50 MHz. The peripheral complement of the LPC11E3x includes up to 128 kB of flash memory, up to 12 kB of SRAM data memory and 4 kB EEPROM, one Fast-mode Plus I²C-bus interface, one RS-485/EIA-485 USART with support for synchronous mode and smart card interface, two SSP interfaces, four general purpose counter/timers, a 10-bit ADC, and up to 54 general purpose I/O pins.

- Two SSP controllers with FIFO and multi-protocol capabilities.
- I²C-bus interface supporting the full I²C-bus specification and Fast-mode Plus witha data rate of up to 1 Mbit/s with multiple address recognition and monitor mode.
- Clock generation:
- Crystal Oscillator with an operating range of 1 MHz to 25 MHz (system oscillator).
- 12 MHz high-frequency Internal RC oscillator (IRC) that can optionally be used asa system clock.
- Internal low-power, low-frequency WatchDog Oscillator (WDO) with programmablefrequency output.
- PLL allows CPU operation up to the maximum CPU rate with the system oscillatoror the IRC as clock sources.
- Clock output function with divider that can reflect the crystal oscillator, the mainclock, the IRC, or the watchdog oscillator.
- Power control:
- Integrated PMU (Power Management Unit) to minimize power consumption duringSleep, Deep-sleep, Power-down, and Deep power-down modes.
- Power profiles residing in boot ROM provide optimized performance and minimizedpower consumption for any given application through one simple function call.
- Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deeppower-down.
- Processor wake-up from Deep-sleep and Power-down modes via reset, selectableGPIO pins, or the watchdog interrupt.
- Processor wake-up from Deep power-down mode using one special function pin.
- Power-On Reset (POR).
- Brownout detect with four separate thresholds for interrupt and forced reset.
