LPC1300 - Low Power 70 MHz, 32-bit Cortex-M3™ MCUs

NXP brings a new level of power performance to the ARM architecture with the LPC1300 series, the industry’s lowest-power Cortex-M3 MCUs. These new microcontrollers 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 2.0 V and 3.6 V), and is available in LQFP-48 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.

Also, in keeping with NXP’s existing line of more than 50 USB equipped ARM MCUs, the LPC134x offers support for USB full-speed operation. HID and mass storage USB driver software is included in a dedicated on-chip ROM, maximizing the amount of Flash memory available for user code.
