NXP LPC1114JHN33/333E is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100XL series, clocked at 50 MHz. The part operates from 1.8 V to 3.6 V and is rated for the -40°C to 105°C industrial temperature range, making it a fit for motor-drive control panels, outdoor telecom modules, and factory-automation sensor nodes where extended temperature is a requirement.
The 50 MHz core speed is the maximum clock for this device. A control loop reading an 8-channel 10-bit ADC and updating a PWM output over SPI can run at several kilohertz without needing a Cortex-M3 or M4.
