Integrator's brief — LPC11U36FBD48/401,
32-bit ARM Cortex-M0 MCU clocked at 50 MHz with 96 KB Flash, 10 KB SRAM, and 4 KB EEPROM on-die. Serial connectivity runs I2C, SPI, SSP, UART/USART, and SmartCard interfaces through 40 GPIOs.
Memory partition — why the EEPROM matters
The 4 KB EEPROM block is the differentiator versus plain Flash-only Cortex-M0 parts. Calibration coefficients, node addresses, or production batch data survive a firmware update without a serial EEPROM on the PCB. The 10 KB SRAM (organized 10K x 8) is tight for USB buffers and a modest RTOS heap; budget the stack and endpoint descriptors first. 96 KB Flash holds a USB stack plus application code for a single-protocol endpoint device.
RoHS3 compliant per the listing.
