That clock rate puts it in the mid-range performance tier for Cortex-M33 parts — enough to handle a real-time control loop, a protocol stack (USB, SPI, I²C), and moderate DSP work without a separate co-processor. The 512 KB Flash and 256 KB SRAM map supports a single firmware image with room for OTA update staging or a data-log buffer. The Flexcomm interface can be configured as I²C, SPI, or UART/USART, giving 36 I/O pins flexible assignment. USB and MMC/SD/SDIO are also present, making this part suitable for a human-machine interface with local storage or a USB-connected data logger.","metaTitle":"NXP LPC55S28JBD64K ARM Cortex-M33 MCU, 150MHz, 512KB Flash","metaDescription":"NXP LPC55S28JBD64K 32-bit ARM Cortex-M33 MCU, 150MHz speed, 512KB Flash, 256KB SRAM, 64-HTQFP, -40°C to 105°C.
