Product details

The NXP LPC11A14FHN33/301, is a 32-bit ARM Cortex-M0 microcontroller running at 50 MHz, with 32 KB of Flash program memory and 8 KB of SRAM. What sets it apart in the LPC11Axx family is the integrated 4 KB EEPROM — that saves an external serial EEPROM for calibration constants or boot parameters. The part also packs an 8-channel 10-bit ADC and a single 10-bit DAC, so it can handle sensor inputs and a simple analog output without extra converters.

Memory mix: why the on-chip EEPROM matters

The 4 KB EEPROM supports byte-by-byte writes and typically tolerates 100k to 1M cycles, suitable for calibration constants or serial numbers. The 8 KB SRAM holds a couple of buffers and a modest stack.

Supply range is 2.6 V to 3.6 V.
