Combined datasheet for the NXP LPC1769, LPC1768, LPC1767, LPC1766, LPC1765, LPC1764 and LPC1763 microcontrollers, a family of ARM Cortex-M3 devices. At 1.26 MB it gathers pin descriptions, package drawings, electrical ratings and peripheral summaries for every variant in one PDF. A repair technician can use it to identify supply and ground pins, locate the reset, crystal and debug interface pins, and compare memory sizes between family members. Confirm the exact part number and package on the chip before trusting a pin assignment.
