The NXP LPC54100 Series of microcontrollers represents a breakthrough in ultra-low-power performance for always-on sensor processing. In an always-on application, the LPC54100 operates in a power-down mode while listening for sensor data. In this low-power state, the LPC54100 only draws 3 μA of current. When sensor data is available, either core can wake up and acquire or process the data. 

For active mode processing, developers can optimize
power efficiency and throughput by choosing between a power-efficient 55 μA/MHz Cortex-M0+ core for sensor data collection, aggregation, and external communications, and a Cortex-M4F processor at 100 μA/MHz, which can complete math-intensive algorithms, such as sensor fusion, more quickly while saving power. A single core Cortex-M4F option is also available for simpler sensor processing architectures or when software partitioning is not required.

LOW POWER ARCHITECTURE

The LPC54100 Series is architected for power efficiency. In addition to the dual-core optimization, the low power interfaces can wake the CPU from power down once data is received. The 12-bit, 12-channel ADC delivers 4.8Msps operation at full spec, including 1.62 V, which perform conversion while the CPU is asleep.

The low-power Flash is writable at 1.62 V. Core and peripheral voltages are automatically scaled for reduced power consumption at any frequency. An asynchronous peripheral bus enables reduced peripheral clock speed without affecting the CPU clock, which minimizes peripheral power consumption.

DEVELOPER ECOSYSTEM

For faster development, LPC54100 devices are available with libraries for popular toolchains, including Keil MDK, IAR EWARM, and the NXP LPCXpresso IDE, a cross-platform C/C++ development suite that supports all of NXP’s LPC microcontrollers.

Also for added convenience NXP offers the LPCXpresso54102 development board for rapid prototyping and evaluation. 

The LPCXpresso54102 board is available for purchase by ordering OM13077.

An application-in-a-box Sensor Processing/Motion Solution provides everything needed to bring sensor-based motion and other sensor-processing applications to market quickly (order# OM13078). The solution includes an LPC54102-based LPCXpresso development board, a sensor shield board with BTLE, and accelerometer, gyroscope, magnetometer, pressure, proximity, temperature, humidity, light, and IR sensors. Software includes LPC54100 software drivers, the LPC Sensor Fusion Framework, and Bosch BSXLite Sensor Fusion (includes development and commercial license).
