The 164 GPIOs give headroom for parallel displays or sensor arrays. ## Lifecycle reality — eol_hot The LPC18S50FET256551 carries an eol_hot lifecycle marker. NXP has ended or is ending production; the part may still be available through surplus or last-time-buy channels. The official base product number is LPC18S50. The part ships in a 256-ball LBGA (17x17 mm) — surface-mount only. Supply voltage spans 2.2 V to 3.6 V. ## Peripherals and data converters On-chip peripherals include brown-out detect, POR, DMA, I²S, LCD controller, PWM, and WDT. The data converters are an 8-channel 10-bit ADC and a single 10-bit DAC — adequate for analog sensor feedback in a motor drive (current sense, encoder) but not high-resolution instrumentation. The LCD controller supports direct panel drive up to a modest resolution, saving an external display driver.","metaTitle":"NXP LPC18S50FET256551 ARM Cortex-M3 MCU, 180 MHz, 200K RAM","metaDescription":"NXP LPC18S50FET256551 32-bit ARM Cortex-M3 MCU, 180 MHz core, 200K x 8 RAM, ROMless, 164 I/O, Ethernet/CAN/USB, -40°C to 85°C, 256-LBGA.
