NXP Semiconductors LPC11E6x 32-bit Arm Cortex-M0+ Microcontrollers
NXP Semiconductors LPC11E6x 32-bit Arm® Cortex®-M0+ Microcontrollers are low-cost MCUs operating at CPU frequencies of up to 50MHz. The LPC11E6x MCUs support up to 256KB of Flash memory, a 4KB EEPROM, and 36KB of SRAM. The Arm Cortex-M0+ is an easy-to-use, energy-efficient core using a two-stage pipeline and fast single-cycle I/O access. The peripheral complement of the LPC11E6x includes a DMA controller, a CRC engine, two I2C-bus interfaces, up to five USARTs, two SSP interfaces, PWM/timer subsystem with six configurable multi-purpose timers, a Real-Time Clock, one 12-bit ADC, temperature sensor, function-configurable I/O ports, and up to 80 general-purpose I/O pins.
