What this part is and where it fits
The NXP LPC1763FBD100Y is a 32-bit ARM Cortex-M3 microcontroller from the LPC17xx series, running at 100 MHz with 256 KB of Flash program memory and 64 KB of SRAM. It comes in a 100-pin LQFP package (14x14 mm) and operates over the industrial temperature range of -40°C to 85°C. This MCU is designed for embedded control tasks that need a balanced mix of processing power, memory, and peripheral integration — think motor drives, industrial communication gateways, and human-machine interfaces where the 100 MHz core handles control loops and protocol stacks without breaking a sweat.
100 MHz — what it means for the control loop
The Cortex-M3 core runs at 100 MHz. This supports real-time control loops and protocol stacks.
Memory sizing for the BOM
256 KB Flash and 64 KB SRAM fit firmware for industrial control and communication tasks.
Peripherals and connectivity — what is on the chip
Temperature grade and environment
Rated for -40°C to 85°C (industrial grade), this MCU is at home in factory automation panels, outdoor telecom cabinets, and automotive cabin modules. The 100-LQFP package is surface-mount, so plan for reflow soldering; the 14x14 mm footprint is standard and fits most two-layer boards with adequate decoupling. No special handling beyond normal ESD precautions — it is a production part, not a lab curiosity.
Lifecycle and sourcing
The LPC1763FBD100Y has an Active lifecycle status. NXP continues to manufacture it with no announced discontinuation.
