10 ns async SRAM for the 5 V bus
The parallel interface means it is a straight drop-in for any design that already has a 44-SOJ footprint and a 16-bit data bus.
Last Buy — plan the final order now
That means Infineon has stopped taking regular production orders, and the window for final purchases is closing. If this SRAM is socketed in an active design, now is the time to commit to a lifetime buy quantity or qualify a replacement. No official successor part is listed on the record, so the replacement path is either a pin-compatible 5 V async SRAM from another vendor or a redesign around a 3.3 V part with a voltage translator.
Industrial temp and the 44-SOJ footprint
The 44-SOJ package (0.400" body width, 10.16 mm) is a JEDEC-standard surface-mount footprint that has been in production for decades — the layout rules are well understood, and the gull-wing leads give a visible solder joint for inspection.
At 10 ns, the address-to-data valid delay is fast enough to support zero-wait-state operation with a 50 MHz bus clock. That matters when the CPU or DMA controller is fetching instructions or buffering packets and cannot afford a dead cycle. If your system runs at 33 MHz or slower, you have generous timing margin; at 66 MHz you will need to check the setup and hold budgets against the controller's specs.
