Product details

50 MHz Cortex-M0 with 8 KB Flash — fit for sensor and control nodes

The NXP LPC1111FHN33/203 is a 32-bit ARM Cortex-M0 MCU from the LPC1100XL series, clocked at 50 MHz. It carries 8 KB of Flash and 4 KB of SRAM, enough for small sensor-fusion firmware or a single control loop with a modest state machine.

On-chip peripherals and watchdog

The 8-channel 10-bit ADC samples analog inputs from thermistors, potentiometers, or current-sense resistors without an external converter.

NXP lists the LPC1111FHN33/203 as Active.
