Product details

The NXP LPC810M021FN8129 is a 32-bit ARM Cortex-M0+ microcontroller from the LPC81xM series, clocked at 30 MHz with 4 KB Flash and 1 KB RAM. It packs a Brown-out Detect/Reset, POR, PWM, and WDT into an 8-DIP through-hole package, with 6 general-purpose I/O and I²C, SPI, and UART connectivity.

Memory: 4 KB Flash, 1 KB RAM — plan the firmware budget

4 KB Flash and 1 KB RAM limit firmware to small control loops.

The 8-DIP (0.300", 7.62 mm) through-hole package is breadboard- and protoboard-friendly, and easy to hand-solder for low-volume builds or repairs.

Frequently asked questions

What is the operating voltage of LPC810M021FN8129?

The supply voltage range is 1.8 V to 3.6 V.

What is the closest pin-compatible alternative to LPC810M021FN8129?

Higher-density siblings in the LPC81xM series (e.g., LPC812M101JD20 with 16 KB Flash) share the same Cortex-M0+ core and DIP package footprint, but the exact pinout and peripheral set should be verified against the datasheet before substitution.
