That access-time figure is the one that decides whether your memory controller can do back-to-back reads at full clock rate or needs to stall. It comes in a 48-TFSOP (18.40 mm width) package, also known as 48-TSOP I, a standard footprint for this density class.
Industrial temperature range — where it lives
The 10 ns write-cycle time (word and page) matches the read access, so the bus timing budget is symmetric — no penalty for mixing read and write transactions.
Package and rework
The Tray shipping medium means the parts arrive aligned in a carrier, not loose in a bag; for hand-assembly or small-batch rework, that saves a sorting step.
