12 ns access time — what it means for the bus
The 12 ns access time sets the window from address valid to data valid on a read cycle. The write cycle time matches at 12 ns, so back-to-back writes at the same speed are possible.
Lifecycle and sourcing
The CY7C1059DV33-12ZSXIT is listed with an EOL lifecycle stage. This means the part is in its last-time-buy or phase-out window. No official successor is recorded. For BOM lines that require this exact density and speed grade, sourcing is through independent distribution — quoted to order against an RFQ, with availability and current pricing confirmed at quote time.
