The LPC11E14FBD48/401 is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 50MHz. The device incorporates 32kB internal flash, 10kB internal RAM, 4kB EEPROM, four general-purpose counters/timers, 8-channel 10-bit A/D converter with sample rates of up to 400ksps and 40 general-purpose I/O pins. This device also features peripherals like one RS-485/EIA-485 USART with support for synchronous mode and smart card interface and one inter-integrated circuit (I2C).
