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 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.

2. Features and benefits

 Dual processor cores: ARM Cortex-M4 and ARM Cortex-M0+. Both cores operate up

to a maximum frequency of 100 MHz.

 ARM Cortex-M4 core (version r0p1):

 ARM Cortex-M4 processor, running at a frequency of up to 100 MHz.

 Floating Point Unit (FPU) and Memory Protection Unit (MPU).

 ARM Cortex-M4 built-in Nested Vectored Interrupt Controller (NVIC).

 Non-maskable Interrupt (NMI) input with a selection of sources.

 Serial Wire Debug (SWD) with six instruction breakpoints, two literal comparators,

and four watch points. Includes Serial Wire Output for enhanced debug

capabilities.

 System tick timer.
