The LPC5411x are ARM Cortex-M4 based microcontrollers for embedded applications. These devices include an ARM Cortex-M0+ coprocessor, up to 192 KB of on-chip SRAM, up to 256 KB on-chip flash, full-speed USB device interface with Crystal-less operation, a DMIC subsystem with PDM microphone interface and I2S, five general-purpose timers, one SCTimer/PWM, one RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Windowed Watchdog Timer (WWDT), eight flexible serial communication peripherals (each of which can be a USART, SPI, or I2C interface), and one 12-bit 5.0 Msamples/sec ADC, and a temperature sensor.
The ARM Cortex-M0+ coprocessor is an energy-efficient and easy-to-use 32-bit core which is code and tool-compatible with the Cortex-M4 core. The Cortex-M0+ coprocessor offers up to 100 MHz performance with a simple instruction set and reduced code size.
