LPC11Axx
32-bit ARM Cortex-M0 microcontroller; up to 32 kB flash, 8 kB
SRAM, 4 kB EEPROM; configurable analog/mixed-signal
Rev. 4 — 30 October 2012
Product data sheet
1. General description
The LPC11Axx are an 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 LPC11Axx operate at CPU frequencies of up to 50 MHz.
Analog/mixed-signal subsystems can be configured by software from interconnected
digital and analog peripherals.
The digital peripherals on the LPC11Axx include up to 32 kB of flash memory, up to 4 kB
of EEPROM data memory, up to 8 kB of SRAM data memory, a Fast-mode Plus I2C-bus
interface, a RS-485/EIA-485 USART, two SSP controllers, four general purpose
counter/timers, and up to 42 general purpose I/O pins.
Analog peripherals include a 10-bit ADC, a 10-bit DAC, an analog comparator, a
temperature sensor, an internal voltage reference, and UnderVoltage LockOut (UVLO)
protection.
2. Features and benefits
