For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

The LPC11xx MCU Family is an Arm Cortex-M0 based low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11xx MCU family is designed for 8/16-bit micro-controller operations, offering performance, low power, simple instruction set with reduced code size.

The peripheral complement of the LPC11xx family includes up to 64 KB of flash memory, up to 8 KB of SRAM, fast-mode plus I2C-bus interface, RS-485/EIA-485 UART, SPI with SSP features, general purpose counters/timers, an Analog to Digital Converter, and up to 42 general purpose I/O pins.

Data Sheet

Application Notes

Product Details

Features

System

Arm Cortex-M0 processor, running at frequencies of up to 50 MHz
Arm Cortex-M0 built-in nested vectored interrupt controller (NVIC)
Non-maskable interrupt (NMI) input selectable from several input sources
Serial wire debug
System tick timer

Memory

Up to 64 KB on-chip flash programming memory
Up to 8 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 LPC1100L and LPC1100XL series
GPIO pins can be used as edge and level sensitive interrupt sources
High-current output driver (20 mA) on one pin
High-current sink drivers (20 mA) on two I2C-bus pins in fast-mode plus (not on LPC1112FDH20/102)
Four general purpose counter/timers with up to eight capture inputs and up to 13 match outputs
Programmable windowed WDT

Analog peripherals

10/12-bit ADC with up to 2 Msamples/s and up to eight channels

Serial interfaces

Up to 3 UARTs with fractional baud rate generation, internal FIFO, and RS-485 support
Up to 2 SPI controllers with SSP features and with FIFO and multi-protocol capabilities
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 (not on LPC1112FDH20/102)

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 with a frequency range of 9.4 kHz to 2.3 MHz
PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the system oscillator or the internal RC oscillator
Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock

Power control

Integrated PMU (Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, and Deep power-down modes
Power profiles residing in boot ROM allowing to optimize performance and minimize power consumption for any given application through one simple function call
Three reduced power modes: Sleep, Deep-sleep, and Deep power-down
Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 13 of the functional pins
Power-On Reset (POR)
Brownout detect with up to four separate thresholds for interrupt and forced reset

Additional features

Unique device serial number for identification
Single power supply (1.8 V to 3.6 V)
Available in WLCSP16, SO20, TSSOP20, TSSOP28, HVQFN24, HVQFN33, TFBGA48 and LQFP48 packages
