Arm Cortex-M3 MCU, 100 MHz, 512 KB Flash, Ethernet + USB OTG + dual CAN, LQFP100
The NXP LPC1768FBD100 is a 32-bit Arm Cortex-M3 microcontroller running up to 100 MHz, with 512 KB on-chip Flash and 64 KB SRAM. It combines a 10/100 Ethernet MAC, a USB 2.0 full-speed Device/Host/OTG controller and two CAN 2.0B channels in a 100-pin LQFP, which makes it a long-running choice for industrial controllers, gateways, building automation and motor-control boards. NXP lists the part as Active.

FAQ
Is the LPC1768FBD100 still in production?
Yes. NXP lists LPC1768FBD100 as Active. Lead times can still stretch on older LPC17xx parts, so share your quantity and need date and we will check current availability across our sourcing network.
What is the difference between LPC1768 and LPC1769?
The LPC1769 runs at up to 120 MHz, while the LPC1768 runs at up to 100 MHz. Memory size and the main peripheral set (Ethernet, USB OTG, dual CAN) are the same, so check clock and timing requirements before treating them as interchangeable.
