The NXP LPC1112FHN33/102K is a 32-bit ARM Cortex-M0 MCU from the LPC1100L series, clocked at 50 MHz with 16 KB of Flash program memory and 2 KB of SRAM. It integrates 28 general-purpose I/O lines, I2C, SPI, and UART/USART serial interfaces, plus an 8-channel 10-bit SAR ADC. The part operates from a 1.8 V to 3.6 V supply and is rated for the -40°C to 85°C industrial temperature range, making it a fit for embedded control in factory automation, sensor nodes, and outdoor telecom gear.
50 MHz Cortex-M0 — what it buys you
The 50 MHz core speed on this Cortex-M0 handles a Modbus RTU poll loop, a PID control update, or a UART-to-I2C bridge without hitting the ceiling.
16 KB Flash and 2 KB RAM place this MCU in the low-density tier, enough for a bootloader plus a modest application.
Supplied in a 32-lead HVQFN with an exposed pad (7×7 mm body).
