The single-cycle 32-bit core delivers roughly 50 MIPS for real-time sensor polling and Modbus RTU framing. 48 KB Flash holds a USB stack, a bootloader, and a moderate application image. 10 KB SRAM leaves room for USB endpoint buffers plus a serial receive ring buffer. 4 KB EEPROM stores calibration constants.","metaTitle":"NXP LPC11U34FBD48/421151 ARM Cortex-M0 MCU, 50 MHz, 48 KB Flash","metaDescription":"NXP LPC11U34FBD48/421151 32-bit ARM Cortex-M0 MCU, 50 MHz, 48 KB Flash, 10 KB SRAM, USB 2.0, 40 I/O, 48-LQFP, -40 to 85°C.
