New MCUs from NXP delivers 32-bit active power consumption at 130 µA/MHz

NXP Semiconductors has released the LPC1100L and LPC1300L microcontrollers, MCUs based on the ARM Cortex-M processor,. These processors deliver low 32-bit active power consumption. The LPC1100L and LPC1300L series introduce a new low-power platform which combines ultra-low leakage design techniques with NXP's optimized power-efficient libraries. The MCUs feature an API-driven power profiles. The LPC1100L and LPC1300L are suggested for lighting controllers, digital power conversion and management systems, portable battery-powered consumer products and accessories.

The LPC1100L microcontroller, based on the ARM Cortex-M0 processor delivers 32-bit active power consumption at 130 µA/MHz and is reported to reduce deep sleep current by 60 percent
The LPC1300L based on the Cortex-M3 processor and provides a performance boost up to 72 MHz, and is pin- and peripheral-compatible with the LPC1100L.

"In addition to offering the industry's lowest 32-bit operating power, LPC1100L now offers new high-level power management profiles allowing runtime optimization of performance, efficiency and battery life with simple API calls," said Geoff Lees, vice president and general manager, microcontroller product line, NXP Semiconductors. "Users no longer need to manage low level register settings to achieve optimal power management."

The LPC1100L and LPC1300L provide API-driven power profiles. The power profiles can be customized for any low-power application allowing designers to reach ideal power levels with minimal application intervention. The power profiles serve as an alternative to non-configurable low power modes. The power profiles enable maximum operating frequency through the voltage range from 1.8V to 3.6V.

Some of the key features of the LPC1100L and LPC1300L series microcontrollers include:

--Speeds of up to 50MHz for the LPC1100L and up to 72MHz for the LPC1300L, which are pin- and peripheral-compatible
--32 vectored interrupts; 4 priority levels; dedicated interrupts on up to 13 GPIOs
--UART, 1-2 SSP, I2C (FM+) as serial peripherals
--Two 16-bit and two 32-bit timers with PWM/Match/Capture
--12 MHz internal RC oscillator with 1 percent accuracy over temperature and voltage
--Power-On-Reset (POR); multi-level Brown-Out-Detect (BOD); Phase-Locked Loop (PLL)
--8-channel high-precision 10-bit ADC with ±1LSB DNL

Availability: The LPC1100L and LPC1300L will be available for ordering from distributors later this month
