150 MHz Cortex-M33 — what it buys you on the bus
The NXP LPC5526JBD100K is a 32-bit ARM Cortex-M33 single-core MCU from the LPC552x series, clocked at 150 MHz. That core speed, combined with a single-cycle multiply and a hardware divide, gives it enough headroom for real-time control loops — think motor-field-oriented control or a CAN gateway handling multiple message streams — without needing an external DSP. The 256 KB Flash and 144 KB SRAM put it in the mid-density tier: enough for a modest RTOS plus application code, but not the part you pick for a camera frame buffer or a large GUI frame store.
The LPC5526JBD100K operates from -40°C to 105°C and accepts a 1.8 V to 3.6 V supply.
Peripherals and I/O — what connects
There is also a USB OTG port, an MMC/SD/SDIO controller, and a 10-channel 16-bit ADC. The Flexcomm scheme means you are not locked into fixed pin assignments — the same pin can serve as a UART TX on one board revision and an SPI clock on the next, as long as you update the firmware's IOCON register map.
It is ROHS3 compliant.
