The NXP LPC5528JBD100K is a 32-bit ARM Cortex-M33 single-core microcontroller running at 150 MHz, with 512 KB Flash and 256 KB SRAM. It belongs to the LPC552x series and is built for industrial-temperature environments (-40°C to 105°C). The 150 MHz clock, combined with the single-cycle multiply and hardware divide of the Cortex-M33, gives this part enough headroom for real-time control loops and protocol stacks running concurrently — think motor-fieldbus gateways or multi-axis servo coordination where the CPU handles both the application and the communication stack without a separate host.
Flexcomm peripherals and I/O budget
Flexcomm modules can be assigned as UART, I²C, or SPI, so the 64 I/O lines can be tailored to the needed serial bus mix.
