The NXP LPC11E36FBD64/501E is a 32-bit ARM Cortex-M0 MCU running at 50 MHz, with 96 KB Flash, 12 KB SRAM, and 4 KB EEPROM. It provides 54 programmable I/O lines in a 64-LQFP package, operating from 1.8 V to 3.6 V over the industrial temperature range of -40 to 85 °C.
The Cortex-M0 core runs at 50 MHz. The 12 KB SRAM supports moderate data buffers.
On-chip EEPROM — calibration data stays put
The 4 KB EEPROM block is the distinguishing feature on this LPC11E3x variant. It holds calibration coefficients, node IDs, or fail-safe parameters independent of Flash endurance cycles. For a sensor node or motor drive that retains trim values across power loss, this saves a separate serial EEPROM and the associated I/O pin.
Connectivity and analog
The part integrates I²C, SPI, SSP, UART/USART, and SmartCard interfaces, plus an 8-channel 10-bit ADC.
