15 ns asynchronous SRAM for industrial cache and buffer duty
Typical applications include cache memory, data buffers, and scratchpad storage in industrial controllers, telecom infrastructure, and automotive electronics where fast, random-access read/write cycles are needed without refresh overhead.
Last Buy — final procurement window
This means Infineon has announced the end of production, and the part is available only through the final ordering window or from surplus/broker channels. Buyers should secure their lifetime buy quantities or qualify a replacement before supply dries up.
The 15 ns access time defines the speed grade of this SRAM. For a system running a 66 MHz bus (15 ns cycle), this part provides zero-wait-state reads if the controller's address-to-data valid window fits within 15 ns. At higher clock rates or with slower controllers, the 15 ns rating gives a clean timing margin that avoids bus contention or data corruption.
2.5 V – 2.7 V supply — narrow rail, no margin for droop
The supply range is 2.5 V to 2.7 V, a tighter window than the typical 2.5 V ±5% or 2.7 V ±10% parts. This means the board must deliver a regulated 2.5 V or 2.7 V rail within 100 mV of the target. If the design already has a 2.5 V or 2.7 V supply, this part drops in cleanly; if the rail is 3.3 V or 1.8 V, an additional regulator is needed.
The 44-TSOP II package with surface-mount leads handles the thermal cycling without solder-joint fatigue common in larger BGA packages.
