Product details

The NXP LPC1766FBD100K is a 32-bit ARM Cortex-M3 MCU from the LPC17xx series, clocked at 100 MHz with 256 KB of Flash and 64 KB of SRAM. The part operates from a single 2.4 V to 3.6 V supply and is specified over the industrial temperature range of -40°C to 85°C, housed in a 100-pin LQFP (14×14 mm) package.

The 100 MHz core executes single-cycle multiply and a 3-stage pipeline. The 64 KB SRAM is split across local and peripheral banks; the DMA engine services Ethernet and USB buffers without CPU intervention.

Supply and temperature grade

Rated for 2.4 V to 3.6 V single-rail operation. The internal oscillator trims to ±1 % accuracy.

Frequently asked questions

What is LPC1766FBD100K's listed speed?

The core runs at 100 MHz, which is the maximum clock from the internal PLL using an external 25 MHz crystal or the internal oscillator.

What compliance documentation does NXP provide for LPC1766FBD100K?

The part is ROHS3 compliant. NXP publishes a material declaration and REACH SVHC statement for the LPC17xx series; these are available on request with the RFQ.
