NXP  LPC11A14FHN33/301  微控制器, 32位, 低功率, ARM 皮质-M0, 50 MHz, 32 KB, 8 KB, 33 引脚, HVQFN

The is a 32-bit Low-power Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 50MHz. Analog/mixed-signal subsystems can be configured by software from interconnected digital and analog peripherals. The device incorporates 32kB internal flash, 8kB internal RAM, 4kB EEPROM, four general purpose counters/timers, 8-channel 10-bit A/D converter with sample rates of up to 400ksps, an analog comparator, a temperature sensor, an internal voltage reference and 28 general-purpose I/O pins. This device also features peripherals like one USART, one inter-integrated circuit I2C and two serial peripheral interface SPI modules.
