32-bit microcontrollers keep power consumption to minimum

The LPC546xx 32-bit microcontrollers from NXP Semiconductors are now in stock at Mouser Electronics. The devices improve dynamic power consumption and provide advanced peripherals that enable designers to create building control, communication, automotive infotainment and navigation, and Internet of Things (IoT) applications.

The microcontrollers are powered by a 180MHz ARM Cortex-M4 core with up to 512kBytes of on-chip flash and up to 200kBytes of SRAM, plus a quad SPI Flash Interface (SPIFI) for expanding program memory.

The ARM core includes a floating point unit (FPU) as well as a memory protection unit (MPU) that separates the memory into distinct regions to improve the reliability of an embedded system.

The devices offer over 21 communication interfaces, including 10 Flexible Serial Interfaces, plus Ethernet support, a TFT LCD controller, and two CAN FD modules.

They feature a programmable power management unit (PMU) that minimises power consumption and matches power requirements at different performance levels and low-power operation with active mode currents down to 3.3mA and deep-sleep mode consumption as low as 22µA.

Mouser is also stocking the LPCXpress54608 development board.

Designed for simple, rapid prototyping and evaluation, LPCXpresso development boards work with the LPCXpresso and MCUXpresso integrated development environments (IDEs) or industry-leading partner toolchains.

The LPCXpresso54608 development board comprises the LPC54608 target device and a Link2 debug probe with CMSIS-DAP and SEGGER J-Link protocol options.

The board also includes a PMod-compatible expansion port and a 10-pin SWD connector for use with third-party debug probes.
