Engineering checkpoints

  • Check the core, flash/RAM, peripherals, pin multiplexing and safety/security requirements together.
  • Confirm debugger, IDE/compiler version, bootloader and in-circuit programming access for production.
  • Compare accuracy, noise, bandwidth, offset/drift and supply/headroom under the actual operating conditions.
  • Check layout, reference, grounding and input/output limits using the device datasheet and evaluation circuit.
