The Flash supports a USB CDC/DFU stack plus a real-time control loop; the SRAM handles double-buffered USB endpoints and a sensor fusion buffer.
The 105°C ceiling allows placement near a power stage without a separate heatsink, as long as local ambient stays under that limit.
The LPC51U68JBD64QL is rated for an operating temperature range of -40°C to 105°C, suitable for industrial and automotive-adjacent environments.
The LPC51U68JBD64QL runs at 100 MHz on its ARM Cortex-M0+ core.
