For designs running a USB HID or CDC class, the combination of a 50 MHz clock and the USB engine keeps the bus responsive without needing a DMA workaround. ## 32 KB Flash and 6 KB RAM — firmware budget With 32 KB of Flash and 6 KB of RAM, the firmware footprint must be managed. The USB stack, application code, and bootloader together need to fit inside that 32 KB. The 6 KB RAM is tight for large data buffers — plan to stream data rather than buffer entire packets. ## Industrial temperature grade","metaTitle":"LPC11U14FET48/201, NXP LPC11U14FET48/201 ARM Cortex-M0 MCU, 50 MHz, 32 KB Flash","metaDescription":"LPC11U14FET48/201 32-bit MCU with 50 MHz Cortex-M0 core, 32 KB Flash, 6 KB RAM, USB 2.0, 40 I/O, -40 to 85°C.
