NXP Semiconductors LPC5411 Series Operational manual

1. General description

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-M4 is a 32-bit core that offers system enhancements such as low power

consumption, enhanced debug features, and a high level of support block integration. The

ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with

separate local instruction and data buses as well as a third bus for peripherals, and

includes an internal prefetch unit that supports speculative branching. The ARM

Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A

hardware floating-point unit is integrated in the core.

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.
