NXP Semiconductors LPC5411 Series Product Data Sheet

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 I
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.
