The NXP Semiconductors LPC13xx is the industry's lowest power ARM Cortex™-M3 microcontroller (MCU). The NXP Semiconductors LPC13xx MCU family consumes approximately 200 µA/MHz, bringing low-power benefits to a wide range of 16- and 32-bit applications. NXP LPC1311, LPC1313, LPC1342, and LPC1343 MCUs operate at CPU frequencies of up to 72 MHz. NXP LPC1311, LPC1313, LPC1342, and LPC1343 MCUs provide a host of high-performance peripheral features, including up to 32kB of Flash memory, up to 8kB of data memory, one Fast-mode Plus I²C-bus interface, one UART, four general-purpose timers, and up to 42 general-purpose I/O pins. The LPC1342 and LPC1343 offer UART or USB selectable boot-up and USB 2.0 full-speed device controller with on-chip PHY for device. The NXP Semiconductors LPC13xx MCU family is designed for use in battery powered systems, e-Metering, consumer peripherals, remote sensors, and 16- / 32-bit applications.
