NXP Semiconductors LPC11xx Arm Cortex-M0 Microcontrollers

NXP Semiconductors LPC11xx Arm Cortex-M0 Microcontrollers (MCUs) offer exceptional power efficiency, a broad selection of package options, and a scalable portfolio with connectivity including USB, LCD, and CAN interfaces. The LPC11xx MCU family is designed for 8/16-bit microcontroller operations, offering performance, low power, simple instruction set with reduced code size compared to existing 8/16-bit architectures. The peripheral complement of the LPC11xx family includes up to 64 KB of flash memory, up to 8KB of SRAM, fast-mode plus I2C-bus interface, RS-485/EIA-485 UART, SPI with SSP features, general-purpose counters/timers, an analog-to-digital converter (ADC), and up to 42 general-purpose I/O pins.
