Single core structure and application of lpc5411x series mcu

The single core (Cortex-M4) and dual core (Cortex-M4 and optional Cortex-M0+) of the LPC5411x family of MCUs provide higher power efficiency for a variety of permanently used applications while providing dual core performance up to 100MHz. It can achieve active current modes as low as 60uA/MHz ; it has a rich peripheral interface that provides a wide range of performance and functional scalability.

The LPC5411x family of MCUs is built on the ARM® Cortex®-M4 core and offers the optional Cortex®-M0+ coprocessor. The ARM® Cortex®-M4 achieves a balance between functional integration and power efficiency, enabling an active current mode of 80uA/MHz; with the industry-leading dual-core option, the Cortex®-M4 layered power solution can be turned off and used The Cortex®-M0+ performs fewer tasks and achieves a lower active current of 60uA/MHz.

The optional on-chip digital microphone (DMIC) subsystem significantly reduces the power consumed in applications that require voice input and processing, enabling the tight power control required for always-on voice activation in battery-powered products. By adding scalability and functional integration, you can achieve ever-increasing applications in areas such as portable devices in the future.

Resource introduction

In addition to an ARM Cortex-M4 core, the LPC5411x family of MCUs also includes an optional ARM Cortex-M0+ coprocessor, up to 192KB of on-chip SRAM, up to 256KB of on-chip flash, full-speed USB device interface, dual-channel PDM microphone Interface and I2S DMIC subsystem, 5 general-purpose timers, a multi-function timer with PWM and other functions (SCTimer/PWM), an RTC/alarm timer, a 24-bit multi-rate timer (MRT), window Watchdog Timer (WWDT), eight selectable serial communication peripherals (each of which can be USART, SPI or I2C interface) and a 12-bit 5.0 Msamples/sec ADC and internal temperature sensor.

Product advantages

● Dual core architecture

Including ARM Cortex-M4 and ARM Cortex-M0+ (optional, using the same clock as Cortex-M4), with advanced high-performance matrix, can not meet the user's low power requirements without the MCU in sleep mode, Cortex- M0+ is used to handle specific tasks and independent software development is possible for each core.

● Flash accelerator

Nearly zero wait state performance, single register settings and API.

● Low power architecture

The LPC5411x family of MCUs offers efficient power efficiency. In addition to dual-core optimization, low-power interfaces can also wake up the CPU after receiving data. At a supply voltage of 1.62V, the 12-bit 12-channel ADC is fully functional 5.0 Msamples/sec for conversion when the CPU is asleep; low-power flash is writable; the core and peripheral voltage are automatically scaled to reduce any frequency Power consumption. The asynchronous peripheral bus reduces peripheral clock speed without affecting the CPU clock, minimizing peripheral power consumption.

● Single power supply wide voltage supply range from 1.62V to 3.6V.

● 128 -bit unique device serial number for chip identification .

● The normal operating temperature range is -40 ° C to +105 ° C.

● Provides WLCSP49 and LQFP64 package for users to choose.
