Obsolete — sourcing this SRAM for production or repair
Any procurement for this part relies on the surplus and aftermarket distribution chain. For a BOM line that cannot be redesigned, the only viable supply path is independent distribution. We source this part on a quoted-to-order basis against an RFQ, confirming availability and current pricing at the time of quote. No factory lead time applies.
With a 15 ns access time, this SRAM can serve a 16-bit microcontroller or DSP running at clock speeds up to roughly 33 MHz without wait states, assuming the controller's read cycle time exceeds 15 ns. At higher clock rates, the bus controller must insert wait states or pipeline the access, which reduces throughput. For legacy designs originally validated with a 15 ns part, substituting a slower memory would break the timing closure.
64K x 16 organization and 3.3 V supply
The 64K x 16 organization provides a 16-bit wide data path in a single chip, matching the native bus width of many 16-bit microcontrollers and digital signal processors. It is also commonly paired with 32-bit processors in a 2-chip configuration for a 32-bit data word.
Industrial temperature grade and 44-SOJ package
The 44-SOJ (Small Outline J-lead) package is a surface-mount footprint that was widely used in the 2000s for memory modules and embedded systems. It is still available in the surplus channel but is not recommended for new PCB layouts due to the limited availability of compatible sockets and the package's obsolescence.
