The CY7C024-15JXC: For existing designs, the only sourcing channel is the independent surplus and broker market, where inventory is lot-specific and confirmed at RFQ.
15 ns access — the timing constraint
At 15 ns access time, this dual-port SRAM delivers a read cycle that keeps pace with a 66 MHz bus without wait states — the address-to-data valid delay is the limiting path, not the write cycle, which also runs at 15 ns per the write cycle time spec. The 4K x 16 organization gives 64 Kbit of shared memory, with both ports able to access any location asynchronously.
84-PLCC footprint and supply rails
The 84-PLCC (J-Lead) package measures 29.31 x 29.31 mm — a large square footprint that requires a through-hole or socketed mount on the board.
