The 93L415FMQB is a standard SRAM organized as 1024 words by 1 bit, with a 70 ns access time and TTL-compatible I/O. It belongs to the 93L415 family of fast asynchronous SRAMs used in cache tag, buffer memory, and control-store applications where a narrow, fast memory word is needed. The 70 ns cycle time suits it for mid-speed microcontroller systems, state machines, and legacy data-acquisition boards that require a simple, direct interface to a TTL bus without the complexity of DRAM refresh.
For procurement, this removes the last-time-buy urgency and allocation pressure that often hit older SRAM families.
Bulk package — handling and assembly note
The 93L415FMQB is, which typically means through-hole DIP or ceramic DIP packaging — not Tape & Reel. This matters for the assembly line: Bulk parts are handled individually, so they suit prototype runs, rework, or low-volume production where a pick-and-place feeder setup isn't justified. No moisture sensitivity level (MSL) concern for ceramic or standard DIP packages, but ESD handling precautions still apply per the datasheet.
