LPC11AXX Overview

Scalable, Entry-Level 32-bit Microcontrollers (MCUs)

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 I

C-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.

I2C port line configuration problem, please answer
If you configure the I2C related I/O port as a general input interface first, and then configure it as an I2C interface, the I2C function test is normal; but if you configure the I/O port as a general...
