The NXP LPC11E37FBD48/501E is a 32-bit ARM Cortex-M0 MCU running at 50 MHz, with 128 KB of Flash program memory, 12 KB of SRAM, and an integrated 4 KB EEPROM block. The 50 MHz core handles interrupt-driven sensor polling, UART buffering, and simple PID loops without stalling the bus.
Peripherals and I/O count
The connectivity block includes I²C, SPI, UART, and SmartCard interfaces — covers the common sensor bus, serial debug, and smartcard reader protocols without external bridge chips.
