Product details

What this tiny Cortex-M0 is for

The NXP LPC1101LVUKZ is a 32-bit ARM Cortex-M0 microcontroller running at 50 MHz, with 32 KB of Flash and 2 KB of RAM in a 25-ball WLCSP package. It operates on a 1.65 V to 1.95 V supply, with 21 GPIOs and I²C, SPI, UART connectivity, rated for -40°C to 85°C.

Package reality — WLCSP is not a field-swap part

The 25-ball WLCSP package requires reflow soldering; it is not field-serviceable. For a hand-solderable alternative, consider the LQFP32 variant in the same LPC1100LV series.

Frequently asked questions

What is the supply voltage range for this MCU?

The LPC1101LVUKZ operates from 1.65 V to 1.95 V, making it suitable for 1.8 V regulated or single-cell Li-ion battery systems.

What is the closest pin-compatible alternative to LPC1101LVUKZ?

The LPC1101LVUKZ is a unique WLCSP variant in the LPC1100LV series. For a pin-compatible alternative in a larger package, consider the LQFP32-packaged members of the same series, though pin mapping should be verified against the NXP datasheet.
