General
Review and verify the following for
the custom schematic design:
- Device selection (selected processor OPN
(Orderable part number) based on the required
features)
- Pin attributes (Ball names,
Signal names and the contents of each column including power) and pin
mapping as per the data sheet
- Pin connectivity requirements (for used and
unused, peripherals)
- Connection recommendations
for RSVD (reserved) pins
- Board debug provision for
probing and measurement (OBSCLK and CLKOUT)
- Errata related to the
supported boot modes and the peripherals of interest
- Recommended operating
conditions, power-up and power-down sequencing for core, memory interface,
analog and IO supplies
- Electrical characteristics and timing information
for selected peripherals
- Application notes, Implementation
recommendations, and Layout guidelines for selected
peripherals
