NXP LPC1100L and LPC1300L MCUs Based on ARM Cortex-M Series Achieve Industry’s Lowest 32-Bit Operating Power

Industry’s Lowest 32-Bit Active Power Consumption
Based on the ARM© Cortex™-M0 processor, the LPC1100L microcontroller delivers the industry‘s lowest 32-bit active power consumption at 130 µA/MHz and reduces deep sleep current by a dramatic 60 percent. The LPC1300L based on the Cortex-M3 processor benefits from similar gains in power efficiency while providing 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.”

Unique API-Driven Power Profiles
The API-driven power profiles featured in the LPC1100L and LPC1300L provide users with ready-to-use power management templates. 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 excellent alternative to non-configurable low power modes, as they can conduct dynamic power management and optimize CPU operation for various application states. This feature minimizes overall energy consumption while maintaining the lowest operating current at low supply voltages. Optimized for CPU performance, CPU efficiency and lowest active current, the power profiles enable maximum operating frequency through the entire voltage range from 1.8V to 3.6V without compromising speed or functionality.

In CPU Performance mode, the microcontroller is configured to increase CPU throughput by providing more processing capability to the application. CoreMark benchmark results have proven that scores increase by 35 percent when compared to regular operation. The CPU Efficiency mode is designed to deliver a fine balance between the CPU’s ability to execute code, process data, and at the same time lower active current consumption. The lowest active current mode is intended for applications that focus on lowering active current, keeping the CPU’s high processing capabilities available as required. CoreMark benchmarks have shown a 20 to 30 percent improvement in power consumption when this mode is enabled.

In addition to its underlying process and system driven power improvements, the LPC1100L and LPC1300L series microcontrollers provide numerous features, including:



* 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
