Product details

The LPC1343FBD48,151: The 72 MHz Cortex-M3 core handles USB interrupt streams alongside control loops. The 8 KB SRAM is tight for heavy buffering.

USB connectivity — no external PHY needed

The integrated USB full-speed device controller handles control, bulk, interrupt, and isochronous transfers. The internal oscillator can serve as the USB clock source.

Frequently asked questions

Can LPC1343FBD48 be used with USB?

Yes, the LPC1343FBD48 includes a full-speed USB 2.0 device controller with integrated PHY, supporting control, bulk, interrupt, and isochronous transfers.

What is the difference between LPC1343 and LPC1342?

The LPC1343 includes a USB 2.0 full-speed device controller; the LPC1342 does not. Both share the same 72 MHz Cortex-M3 core, 32 KB Flash, 8 KB SRAM, and 48-LQFP pinout, so the LPC1343 is a drop-in upgrade if USB is needed.

What is the pinout of LPC1343FBD48?

The LPC1343FBD48 is supplied in a 48-pin LQFP package (7x7 mm). The pinout is standard for the LPC13xx family and is documented in the NXP datasheet; the 48-LQFP footprint is shared with the LPC1342 and LPC1345 for pin-compatible upgrades.
