Scalable, Entry-Level 32-bit Microcontrollers (MCUs)
The LPC11xxLV MCU family is an Arm® Cortex®-M0 based low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11xxLV MCU family is designed for 8/16-bit micro-controller operations, offering performance, low power, simple instruction set with reduced code size compared to existing 8/16-bit architectures.
The peripheral complement of the LPC11xxLV MCU family includes up to 32 KB of flash memory, up to 8 KB of SRAM, a fast-mode Plus I2C-bus interface, one UART, one SPI/SSP interface, four general purpose counters/timers, an 8-bit ADC, and up to 27 general purpose I/O pins.

Features
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
- Up to 32 KB on-chip flash programming memory with a 256 byte page erase function
- Up to 8 KB SRAM
- In-system programming (ISP) and in-application programming (IAP) via on-chip bootloader software
Digital peripherals
- Up to 27 general purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors and a configurable open-drain mode
- GPIO pins can be used as edge and level sensitive interrupt sources
- High-current output driver on one pin
- High-current sink drivers on two I2C-bus pins in fast-mode plus
- Four general purpose counter/timers with a total of 7 capture inputs and 13 match outputs
- Programmable windowed watch dog timer (WDT)
Analog peripherals
- 8-bit ADC with input multiplexing among 8 pins
Serial interfaces
- UART with fractional baud rate generation and internal FIFO
- One 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
Clock generation
- 12 MHz internal RC oscillator trimmed to 2.5 % accuracy for Tamb= -20 °C to +85 °C and to 5 % accuracy for Tamb = -40 °C to -20 °C. The IRC 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, CPU clock, and the Watchdog clock
Power control
- Two reduced power modes: Sleep and deep-sleep mode
- Ultra-low power consumption in deep-sleep mode
- 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 Detection (BOD) causing a forced reset
Additional features
- Device serial number for identification
- Single power supply (1.65 V to 1.95 V)
- Available as WLCSP25, HVQFN24, HQFN33
