The LPC1114JHI33/303E: 32-bit ARM Cortex-M0 MCU from the LPC1100XL series, clocked at 50 MHz. 32 KB Flash, 8 KB RAM, 28 I/O, 8-channel 10-bit ADC, 1.8 V to 3.6 V supply.
The 50 MHz core at 105°C meets timing on the internal oscillator; no external crystal needed for basic operation.
NXP lists the LPC1114JHI33/303E as Active. ROHS3 compliant.
The 8×10-bit ADC handles analog inputs like potentiometer feedback or thermistor readings.
Within the LPC1100XL series, other density variants (e.g., LPC1114 with different Flash/RAM sizes) share the same 32-HVQFN footprint and pinout. For a direct drop-in with identical memory, the base number LPC1114 covers multiple temperature and package options — verify the suffix for your required grade.
