If you are searching for a high-performance, power efficient, yet cost sensitive MCU for your designs, then here is the exciting news: NXP recently introduced the LPC51U68 MCU.
Power efficient solution for future IoT designs
Based on the Arm® Cortex®-M0+ core, the LPC51U68 MCU pushes the performance of the core to 100MHz, which is more than two times faster than current Cortex-M0+-based products. The LPC51U68 MCU also provides expanded memory resources of up to 96KB on-chip SRAM and 256 KB on-chip flash programming memory with flash accelerator. It also features unparalleled design flexibility and integration including a USB 2.0 full-speed device controller supporting crystal-less operations, eight flexible serial communication peripherals, each of which can be enabled as UART, SPIs or I2C and up to two I2S interfaces. The LPC51U68 MCU integrates a variety of timers including three general purpose timers, one versatile timer with PWM (SCTimer/PWM), one RTC/alarm timer, a multi-rate timer and watchdog timers. On the analog side, an on-chip 12-channel ADC with a 12-bit resolution and conversion rates at up to 5Msps and temperature sensors are provided. With all the features integrated, the LPC51U68 MCU brings unparalleled design flexibility, computing performance and integration into today’s demanding IoT and industrial applications.
While considering the LPC51U68 MCU as an upgrade of the LPC11U68 MCU family, it provides pin-function compatibility with Arm® Cortex®-M4 based LPC5410x and LPC5411x MCU families in the same packages and pinout versions enabling a smooth transition to the power-efficient MCUs based on Arm® Cortex®-M4 core.
Low power design for energy efficiency
While providing excellent computing power with the Arm Cortex-M0+ core, the LPC51U68 MCU displays ultra-low-power consumption and a unique low-power design. The microcontroller supports four low-power modes and API-driven power profiles, providing developers with easy-to-use dynamic current management at runtime and fast wake-up times from the microcontroller’s reduced power modes.
Make your design easier with tools supported
LPC51U68 MCUs are fully supported by NXP’s MCUXpresso software and tools which brings together the best of NXP’s software enablement into one enablement platform for a shared software experience across a broader set of Arm® Cortex®-M MCUs. In addition, this new MCU is supported by the LPCXpresso51U68 development board, designed to enable evaluation and prototyping with the LPC51U68 MCU. The board features an on-board, CMSIS-DAP / SEGGER J-Link compatible debug probe, expansion options based on Arduino™ UNO and PMod™, plus additional expansion port pins and more
