The NXP LPC1768UKZ is a 32-bit ARM Cortex-M3 microcontroller from the LPC17xx series, clocked at 100 MHz. The connectivity set is what sets it apart: Ethernet, USB OTG, and CANbus on one die, so you can bridge a factory network to a vehicle bus or a field-service laptop without extra PHY chips. Supply voltage runs 2.4 V to 3.6 V.
100 MHz on a Cortex-M3 provides single-cycle multiply and hardware divide.
Package reality — WLCSP is not field-swappable
The 100-WLCSP (5.07 × 5.07 mm) is a wafer-level chip-scale package with no leads.
