Product details

Memory split: 128 KB Flash, 12 KB RAM, 4 KB EEPROM

128 KB Flash covers moderate application firmware plus bootloader space; the 12 KB SRAM is tight for large data buffers — plan DMA or double-buffering carefully if handling audio or high-rate ADC captures. The 4 KB EEPROM is a hardware EEPROM block, not emulated Flash, so you get 100k+ write-cycle endurance for calibration constants or configuration parameters without external serial EEPROM.

LPC11E37FBD48/501Y carries an Active lifecycle status per NXP — no last-time-buy notice currently in effect. For dual-sourcing resilience, NXP's LPC11E3x family shares pin-compatible footprints across density options, so a swap to a sibling with different Flash/RAM is a board-layout match.

Frequently asked questions

What is the closest pin-compatible alternative to LPC11E37FBD48/501Y?

NXP's LPC11E3x family offers pin-compatible siblings with different Flash/RAM densities in the same 48-LQFP footprint. The LPC11E37FBD48/501Y is the 128 KB Flash / 12 KB RAM variant; stepping up or down in memory keeps the same pinout and peripheral set.

What is LPC11E37FBD48/501Y's listed speed?

The core runs at 50 MHz maximum clock frequency, based on the ARM Cortex-M0 architecture.

What compliance documentation is available for this part?

NXP provides RoHS and REACH declarations for the LPC11E3x series. The 48-LQFP package is lead-free and compatible with standard reflow profiles. Specific certificates can be requested at quote time.
