55 ns access time — timing margin for the bus
The 55 ns access time is the time from address valid to data valid on a read cycle. The write cycle time is also 55 ns, so the same timing applies to writes.
Lifecycle and sourcing reality
This part carries an Active product status — no end-of-life notice, no last-time-buy clock ticking. It is ROHS3 compliant, which covers the current EU RoHS exemption list. For a BOM line that needs a 32 Mbit parallel SRAM in a 48-ball BGA, this is a production-qualified choice with no imminent obsolescence risk.
