Product details

Memory map and the EEPROM advantage

50 MHz Cortex-M0 — what it means for throughput

The 50 MHz core delivers about 50 DMIPS for the Cortex-M0 pipeline. That is enough to handle USB full-speed with a software stack, manage I²C and SPI peripherals concurrently, and run a modest control loop.

USB and serial connectivity

The USB device interface is the headline peripheral here. Combined with SmartCard and Microwire support, this MCU targets secure-credential readers, USB-to-serial adapters, and smart-grid meters.

Standard distribution lead times apply; no last-time-buy notice is in effect. For dual-sourcing resilience, NXP's LPC11Uxx family includes pin-compatible density variants (e.g., 32 KB Flash versions) that share the same 32-HVQFN footprint — qualifying one opens the door to others without a board spin.

Frequently asked questions

What is the closest pin-compatible alternative to LPC11U35FHN33/401?

NXP offers pin-compatible density variants in the LPC11Uxx family, such as the LPC11U35FHN33/201 (32 KB Flash) and LPC11U35FHN33/501 (128 KB Flash), all in the same 32-HVQFN package. Qualifying one variant simplifies BOM flexibility without a PCB layout change.

What is the listed speed of LPC11U35FHN33/401?

The core processor runs at 50 MHz, which is the maximum clock for this ARM Cortex-M0 device in the LPC11Uxx series.

What compliance documentation does NXP provide for LPC11U35FHN33/401?

The part is ROHS3 compliant. NXP provides the standard RoHS certificate of compliance and material declaration. No UL or IEC certification is listed for this component.
