Product details

The 16 KB Flash and 4 KB RAM suit a bootloader plus one application image. The 2 KB EEPROM stores calibration constants without an external part.

Package reality — WLCSP handling

The 20-WLCSP (2.55 x 2.55 mm) is a wafer-level chip-scale package with solder balls on the underside. It saves board area — about the size of a grain of rice — but it is not a hand-solder part. You need a stencil, a reflow oven, and X-ray inspection to verify the joints. For field swaps, plan on hot-air rework or a pre-programmed spare on a carrier board. The upside: the small footprint lets you pack this MCU into a sensor housing or a dongle where a QFN would not fit.

Frequently asked questions

What is the package and footprint for LPC11A02UK,118?

The LPC11A02UK,118 comes in a 20-WLCSP package measuring 2.55 x 2.55 mm. It is a wafer-level chip-scale package with solder balls — requires reflow assembly, not hand-solder.

What are the key specifications of LPC11A02UK,118?

The LPC11A02UK,118 runs a 32-bit ARM Cortex-M0 core at 50 MHz, with 16 KB Flash, 4 KB RAM, and 2 KB EEPROM. It has 18 I/O lines, I²C/SPI/UART connectivity, an 8-channel 10-bit ADC, a single 10-bit DAC, and an internal oscillator. Operating temperature range is -40 to 85 °C.
