120 MHz core and memory budget
The LPC1759FBD80K: The 120 MHz Cortex-M3 core delivers single-cycle multiply and hardware divide, which matters for control-loop math and protocol parsing where every microsecond counts. The 64 KB SRAM supports a few kilobytes of stack and heap plus a pair of DMA buffers; designs that need extensive data logging or large packet buffers should budget RAM carefully.
Housed in an 80-pin LQFP with a 12x12 mm body, the LPC1759FBD80K is a surface-mount part suited for automated assembly on standard PCB processes.
