50 MHz Cortex-M0 with on-chip EEPROM
The NXP LPC11E37HFBD64/401151 is a 32-bit ARM Cortex-M0 MCU from the LPC11E3x series, clocked at 50 MHz.
Rated -40 to 85 °C. The 64-LQFP (10x10 mm body) is a standard layout.
On-chip peripherals for real-time control
The peripheral set includes a 10-bit 8-channel ADC, PWM timers, a watchdog, brown-out detect, and a POR circuit — enough for closed-loop fan control, analog sensor readout, or simple motor commutation on a 3-phase BLDC auxiliary fan.
Active production — normal sourcing
Lifecycle status is Active per NXP's product record.
