Product details

The NXP LPC1768FBD100K is a 32-bit ARM Cortex-M3 microcontroller running at 100 MHz, with 512 KB of Flash and 64 KB of RAM on-chip. It carries Ethernet, USB OTG, and CAN interfaces alongside the usual I²C, SPI, UART, and SSI — enough connectivity to serve as the main controller in an industrial gateway, a motor-drive node, or a networked sensor hub. The 70 GPIOs and the 8-channel 12-bit ADC plus a single 10-bit DAC cover mixed-signal I/O without an external converter on simpler designs.

The LPC1768FBD100K runs at 100 MHz.

NXP continues to manufacture this part, so new designs can proceed without an end-of-life clock.

For a BOM freeze, the active status means no urgent last-time-buy pressure, but lead times should be verified per your volume window.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1768FBD100K in this family?

Within the LPC17xx series, the LPC1769FBD100 runs at 120 MHz with the same 512 KB Flash and 64 KB RAM in the same 100-LQFP footprint. The LPC1768FBD100K is also pin-compatible with the LPC1766FBD100 (256 KB Flash, 64 KB RAM) for cost-down builds where the extra Flash is not needed.

What is LPC1768FBD100K's listed speed?

The core runs at 100 MHz. That clock rate drives the Cortex-M3 to about 125 DMIPS, enough for real-time control loops and Ethernet protocol stacks without external accelerators.
