Product details

The NXP LPC1754FBD80K is a 32-bit ARM Cortex-M3 MCU from the LPC17xx series, clocked at 100 MHz with 128 KB Flash and 32 KB RAM. It packs CAN, USB OTG, I²C, SPI, and UART interfaces, plus a 6-channel 12-bit ADC and a 10-bit DAC.

100 MHz Cortex-M3 — what it buys you on the bus

At 100 MHz, this core runs control loops and protocol stacks. The 32 KB RAM is enough for a couple of 1 KB CAN message buffers.

CAN + USB OTG — dual-interface industrial gateway on a chip

With both CAN and USB OTG on the same die, this MCU can serve as a protocol bridge between a CAN bus and a USB host.

Supply range is 2.4 V to 3.6 V. The 80-LQFP package (12x12 mm) is hand-solderable.

Frequently asked questions

What is the closest pin-compatible alternative to the LPC1754FBD80K?

Within the LPC17xx series, the LPC1756 and LPC1758 are pin-compatible upgrades with larger Flash (256 KB and 512 KB respectively) and the same 80-LQFP footprint. They drop in without a board change if you need more code space.

What is the core speed of the LPC1754FBD80K?

The ARM Cortex-M3 core runs at 100 MHz, which is the maximum clock speed for this device.
