- 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)
