NXP Semiconductors brings a new level of power performance to the ARM architecture with the LPC1300 series, one of the industry’s lowest-power Cortex-M3 MCUs. These new MCUs consume approximately 200 μA/MHz, bringing low-power benefits to a wide range of 16/32-bit applications.
Built around a Cortex-M3 Rev2 processor core, the LPC1300 is equipped with up to 32 kB of flash and up to 8 kB of SRAM, uses a single 3.3 V power supply (for operation between 1.8 V and 3.6 V), and is available in LQFP48 and HVQFN 33 packages.
The LPC1300 series is pin-to-pin compatible with the LPC1100 series, NXP’s new family of Cortex-M0 MCUs, so it gives designers a straightforward migration path to the even lower-power features of the Cortex-M0 architecture.
