32-bit Cortex-M0 at 50 MHz — entry-level control with industrial temperature coverage
The NXP LPC1111FHN33/202551 is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100L series, clocked at 50 MHz with 8 KB Flash and 4 KB SRAM. It carries 28 general-purpose I/O lines, I²C, SPI, and UART/USART connectivity, plus an 8-channel 10-bit ADC.
8 KB Flash — firmware footprint planning
With 8 KB of Flash, firmware must be lean. The LPC1100L series includes a boot ROM with in-system programming via UART, so the application code can fit entirely in Flash without a separate bootloader. Brown-out detect, POR, and watchdog peripherals are on-chip, reducing external component count.
