Scalable, Entry-Level 32-bit Microcontrollers (MCUs)

The LPC11Axx MCU family is an Arm^® Cortex^®-M0 based low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11Cxx MCU family is designed for 8/16-bit microcontroller operations, offering performance, low power, simple instruction set with reduced code size.

模拟/混合信号子系统可通过软件从互连的数字和模拟外设进行配置。The digital peripherals of the LPC11Axx MCU family includes up to 32 KB of flash memory, up to 8 KB of SRAM data memory, up to 4 KB of EEPROM data memory, a fast-mode Plus I2C-bus interface, a RS-485/EIA-485 USART, 2 SSP controllers, 4 general purpose counters/timers, and up to 42 general purpose I/O pins. In addition, the analog peripherals include a 1-bit ADC, a 10-bit DAC, an analog comparator, a temperature sensor, an internal voltage reference and under-voltage lockout (UVLO) protection.
