The LPC541xx MCU family of single-core and dual-core MCUs represents the next-generation of industry-leading power efficiency. With added scalability and feature integration, these breakthrough devices enable continued market growth in today"s competitive always-on environment.
LPC541xx MCUs are based on the power-efficient ARM® Cortex-M4 core, each with an optional Cortex®-M0+ coprocessor. Single Cortex-M4 options are available for architectures that value single core processing without software partitioning.
In an always-on application, these MCUs operate in a power-down mode, listening for incoming data, which when available, can wake either core to acquire or process the information. When in an active mode, developers can optimize power efficiency and throughput by choosing between the power-efficient Cortex-M0+ core for data collection, aggregation, and system task management, or the Cortex-M4 core, which can complete processor intensive algorithms, such as sensor fusion more quickly helping to reduce power consumed.
The optional dedicated on-chip digital microphone (DMIC) subsystem on the LPC54110 family will also dramatically reduce power in applications that demand voice input and processing, achieving the stringent power efficiencies required for always-on voice-activation in battery-operated products.

* 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 break points, two literal comparators, and four watch points. Includes Serial Wire Output for enhanced debug capabilities.
* System tick timer.
### ARM Cortex-M0+ core
* ARM Cortex-M0+ processor, running at a frequency of up to 100 MHz (uses the same clock as Cortex-M4) with a single-cycle multiplier and a fast single-cycle I/O port.
* ARM Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC).
* Serial Wire Debug with four breakpoints and two watch points.
### On-chip memory
* Up to 256 KB on-chip flash program memory with flash accelerator and 256-byte page erase and write.
* Up to 192 KB total SRAM consisting of 160 KB contiguous main SRAM and an additional 32 KB SRAM on the I&D buses.
### ROM API supports
* Flash In-Application Programming (IAP) and In-System Programming (ISP).
* ROM-based USB drivers (HID, CDC, MSC, and DFU). Flash updates via USB is supported.
* Supports booting from valid user code in flash, USART, SPI, and I2C.
* Legacy, Single, and Dual image boot.
### Serial interfaces
* Flexcomm Interface contains eight serial peripherals. Each can be selected by software to be a USART, SPI, or I2C interface. Two Flexcomm Interfaces also include an I2S interface. Each Flexcomm Interface includes a FIFO that supports USART, SPI, and I2S if supported by that Flexcomm Interface. A variety of clocking options are available to each Flexcomm Interface and include a shared fractional baud-rate generator.
* I2C-bus interfaces support Fast-mode and Fast-mode Plus with data rates of up to 1Mbit/s and with multiple address recognition and monitor mode. Two sets of true I2C pads also support high speed mode (3.4 Mbit/s) as a slave.
* Crystal-less USB full-speed device interface.
### Digital peripherals
* DMA controller with 20 channels and 20 programmable triggers, able to access all memories and DMA-capable peripherals.
* Up to 48 General-Purpose Input/Output (GPIO) pins. Most GPIOs have configurable pull-up/pull-down resistors, programmable open-drain mode, and input inverter.
* GPIO registers are located on the AHB for fast access.
* Up to eight GPIOs can be selected as pin interrupts (PINT), triggered by rising, falling or both input edges.
* Two GPIO grouped interrupts (GINT) enable an interrupt based on a logical (AND/OR) combination of input states.
* CRC engine.
### Analog peripherals
* 12-bit ADC with 12 input channels and with multiple internal and external trigger inputs and sample rates of up to 5.0 MSamples/sec. The ADC supports two independent conversion sequences.
* Integrated temperature sensor connected to the ADC.
### Timers
* Five 32-bit standard general purpose timers/counters, four of which support up to four capture inputs and four compare outputs, PWM mode, and external count input. Specific timer events can be selected to generate DMA requests. The fifth timer does not have external pin connections and may be used for internal timing operations.
* One SCTimer/PWM with eight input and eight output functions (including capture and match). Inputs and outputs can be routed to or from external pins and internally to or from selected peripherals. Internally, the SCTimer/PWM supports ten captures/matches, ten events, and ten states.
* 32-bit Real-time clock (RTC) with 1 s resolution running in the always-on power domain. A timer in the RTC can be used for wake-up from all low power modes including deep power-down, with 1 ms resolution.
* Multiple-channel multi-rate 24-bit timer (MRT) for repetitive interrupt generation at up to four programmable, fixed rates.
* Windowed Watchdog Timer (WWDT).
### Clock generation
* 12 MHz internal Free Running Oscillator (FRO). This oscillator provides a selectable 48 MHz or 96 MHz output, and a 12 MHz output (divided down from the selected higher frequency) that can be used as a system clock. The FRO is trimmed to ±1 % accuracy over the entire voltage and temperature range.
* External clock input for clock frequencies of up to 25 MHz.
* Watchdog oscillator (WDTOSC) with a frequency range of 6 kHz to 1.5 MHz.
* 32.768 kHz low-power RTC oscillator.
* System PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency external clock. May be run from the internal FRO 12 MHz output, the external clock input CLKIN, or the RTC oscillator.
* Clock output function with divider.
* Frequency measurement unit for measuring the frequency of any on-chip or off-chip clock signal.
### Power control
* Programmable PMU (Power Management Unit) to minimize power consumption and to match requirements at different performance levels.
* Reduced power modes: sleep, deep-sleep, and deep power-down.
* Wake-up from deep-sleep modes due to activity on the USART, SPI, and I2C peripherals when operating as slaves.
* The Micro-Tick Timer running from the watchdog oscillator can be used to wake-up the device from any reduced power modes.
* Power-On Reset (POR).
* Brown-Out Detect (BOD) with separate thresholds for interrupt and forced reset.
