72 MHz Cortex-M3 with on-chip EEPROM and CANbus
The NXP LPC1548JBD100E is a 32-bit ARM Cortex-M3 MCU running at 72 MHz, with 128 KB Flash, 20 KB RAM, and a separate 4 KB EEPROM block — the EEPROM saves you an external serial memory chip for calibration constants or boot parameters that need to survive a firmware update. On-chip CANbus and USB give it the two most common industrial and debug interfaces without an external transceiver on the USB side (the CAN PHY is still external). The 24-channel 12-bit ADC covers multi-sensor analog front-ends without an external mux.
The 100-LQFP package (14x14 mm body) provides 76 GPIOs.
The DMA engine can service the ADC and serial peripherals without CPU intervention — useful when the 72 MHz core is busy with a control loop or protocol stack. SPI, I²C, and multiple UARTs round out the sensor and actuator interface options.
Lifecycle status is Active — no last-time-buy window, no broker dependency.
