The 8 KB SRAM is the tighter constraint; firmware using USB bulk transfers or multiple serial buffers will need careful memory mapping. ## Industrial temperature grade — where it sits The internal oscillator keeps the core running across the full temperature span, so no external crystal is needed for basic operation. ## 48-LQFP package — rework and layout notes The 48-LQFP (7x7 mm body) is a fine-pitch surface-mount package. It is reworkable with hot air if the board has adequate thermal relief on the ground pads — the exposed pad is not present on this package, so the risk of lifting a pad is lower than with QFN. Pin 1 is marked by a chamfer on the top-left corner; verify orientation before placement. The 40 I/O lines include the USB D+/D- pair, which need controlled-impedance routing if the trace exceeds 50 mm. ## Memory budget — firmware fit check 24 KB Flash and 8 KB SRAM are entry-level figures. The 1 KB EEPROM is useful for calibration constants or configuration parameters that survive a firmware update.","metaTitle":"NXP LPC11U23FBD48/301, ARM Cortex-M0 MCU, 50 MHz, 24 KB Flash","metaDescription":"NXP LPC11U23FBD48/301, 32-bit ARM Cortex-M0 MCU at 50 MHz with 24 KB Flash, 8 KB RAM, USB, I²C, SPI.
