The NXP LPC5516JBD100E is a 32-bit single-core ARM Cortex-M33 microcontroller running at 150 MHz, with 256 KB of Flash program memory and 96 KB of RAM. It sits in the LPC551x series, aimed at industrial control, motor drives, and automotive body electronics where a balance of processing throughput, peripheral integration, and extended temperature range is needed. The 150 MHz core clock handles real-time control loops and protocol stacks. The 256 KB Flash is sized for mid-complexity applications. On the connectivity side, the part integrates CANbus, USB, and Flexcomm — a configurable serial interface that can be assigned as I²C, SPI, or UART per pin group. That means one part can cover a CAN gateway, a USB-to-serial bridge, and multiple sensor buses without external protocol chips. The 10-channel 16-bit SAR ADC samples at rates suitable for current sensing and analog input monitoring in motor drives or power converters.
Industrial temperature range and package — fit for harsh environments
The 100-LQFP exposed-pad package (14x14 mm body) provides a thermal path through the pad to the PCB copper plane — important when the core draws sustained current at 150 MHz.
