It carries 256 KB Flash and 144 KB RAM, with a Flexcomm interface that multiplexes I²C, SPI, UART, USART, and SDIO onto shared pins — reducing BOM routing complexity in mixed-protocol designs. The 10-channel 16-bit ADC captures analog sensor data without an external converter, and the USB Full-speed port handles device-to-host communication directly. ## Active lifecycle — no obsolescence concern That means NXP continues to manufacture it, and there is no last-time-buy or phase-out window on the horizon. For a BOM freeze or a new design, this part is a safe selection without a forced migration path. No direct pin-compatible equivalent is listed; the LPC55S6x family shares the same footprint across density options, so a Flash/RAM upgrade within the series is possible without a PCB spin.","metaTitle":"NXP LPC55S66JEV98K ARM Cortex-M33 MCU, 150 MHz","metaDescription":"NXP LPC55S66JEV98K, 32-bit ARM Cortex-M33 MCU at 150 MHz, 256 KB Flash, 144 KB RAM, Flexcomm, USB, 16-bit ADC, -40 to 105°C, 98-VFBGA.
