Product Details

Select a section:



  • Cortex-M0 or Cortex-M0+ processor, running at frequencies of up to 50 MHz
  • Cortex-M0 or Cortex-M0+ built-in nested vectored interrupt controller (NVIC)
  • Serial wire debug (SWD) and JTAG boundary scan modes supported
  • System tick timer


  • Up to 256 KB on-chip flash programming memory with page erase
  • Up to 32 KB main SRAM
  • Up to two additional SRAM blocks of 2 KB each (LPC11U6x parts)
  • Up to 4 KB EEPROM
  • In-System programming (ISP) and In-Application programming (IAP)

Digital peripherals

  • Simple DMA engine with 16 channels and programmable input triggers (LPC11U6x)
  • Up to 80 General purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors
  • Pin interrupt and pattern match engine using eight selectable GPIO pins (LPC11U6x)
  • Two GPIO interrupt generators (LPC11U6x)
  • CRC engine (LPC11U6x)
  • Programmable windowed watchdog timer (WDT)
  • Up to four 32-bit and two 16-bit counter/timers or two 32-bit and six 16-bit counter/timers
  • Up to 21 match outputs and 16 capture inputs
  • Up to 19 PWM outputs with 6 independent time bases

Analog peripherals

  • One 10/12-bit ADC with up to 12 input channels and sample rates of up to 2 Msample/s
  • Temperature sensor (LPC11U6x)

Serial interfaces

  • USB 2.0 full-speed device controller. XTAL-less low-speed mode supported
  • Up to five USART interfaces with RS-485 mode support
  • Up to two SSP controllers
  • Up to two I²C-bus interfaces

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
  • Programmable watchdog oscillator
  • PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal
  • A second, dedicated PLL is provided for USB
  • Clock output function with divider that can reflect the crystal oscillator clock, the main clock, the IRC, or the Watchdog oscillator

Power control

  • Integrated PMU (Power Management Unit) to minimize power consumption
  • Power profiles residing in boot ROM provide optimized performance and minimized power consumption for any given application through one simple function call
  • Four reduced power modes: Sleep, Deep-sleep, Power-down and Deep power-down modes
  • Processor wake-up from Deep-sleep and Power-down modes on external pin inputs
  • Power-On Reset (POR)
  • Brownout detect

Additional features

  • Unique device serial number for identification
  • Single power supply (1.8 V to 3.6 V - LPC11U1x, LPC11U2x and LPC11U3x) (2.4 V to 3.6 V - LPC11U6x)
  • Available as LQFP48, LQFP64, LQFP100, TFBGA48 and HVQFN33 packages
  • Real-time clock (RTC) in the always-on power domain with separate battery supply pin and 32 kHz oscillator (LPC11U6x)
