1. General description The LPC11U3x are an ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The LPC11U3x operate at CPU frequencies of up to 50 MHz. Equipped with a highly flexible and configurable full-speed USB 2.0 device controller, the LPC11U3x brings unparalleLED design flexibility and seamless integration to today’s demanding connectivity solutions. The peripheral complement of the LPC11U3x includes up to 128 kB of flash memory, up to 12 kB of SRAM data memory and 4 kB EEPROM, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 USART with support for synchronous mode and smart card interface, two SSP interfaces, four general purpose counter/timers, a 10-bit ADC, and up to 54 general purpose I/O pins. The I/O Handler is a software library-supported hardware engine that can be used to add performance, connectivity and flexibility to system designs. It is available on the LPC11U37HFBD64/401. The I/O Handler can emulate serial interfaces such as UART, I 2C, and I2S with no or very low additional CPU load and can off-load the CPU by performing processing-intensive functions like DMA transfers in hardware. Software libraries for multiple I/O Handler applications are available on nxp.com. For additional documentation related to the LPC11U3x parts, see Section 15 “References”. 2. Features and benefits ?
