Product details

The NXP LPC1111JHN33/103E is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100XL series, clocked at 50 MHz. It carries 8 KB of Flash and 2 KB of RAM — enough for sensor polling, relay logic, or a simple serial bridge, but tight for a protocol stack or a GUI. The 28 GPIOs and 8-channel 10-bit ADC suit it for I/O-heavy control boards in industrial or outdoor equipment, backed by the -40 to 105 °C temperature grade.

8 KB Flash and 2 KB RAM define the firmware ceiling. That is enough for a Modbus RTU slave, a few PID loops, or a keypad-and-LED controller.

Frequently asked questions

What is the LPC1111JHN33/103E's core speed and memory?

The ARM Cortex-M0 core runs at 50 MHz, with 8 KB of Flash program memory and 2 KB of SRAM. That is a lean memory footprint suited for simple control and communication tasks.

What is the closest pin-compatible alternative to the LPC1111JHN33/103E?

The LPC1100XL family includes higher-density siblings (e.g., LPC1112 with 16 KB Flash, LPC1114 with 32 KB Flash) in the same 32-HVQFN package. They are pin-compatible and code-compatible, making them a drop-in upgrade path without a PCB change.
