ZBT SRAM with 3.2 ns access — what the speed grade buys you
The MT55V512V32PT-5 is a Micron ZBT (Zero Bus Turnaround) SRAM organized as 512K x 32 bits, delivering 18 Mbit of volatile storage. The 3.2 ns access time and 200 MHz bus frequency mean the part can sustain back-to-back reads without dead cycles — the ZBT pipeline eliminates the turnaround cycle that conventional sync SRAMs insert between read and write operations.
Active lifecycle and cross-reference reality
The ZBT SRAM market is narrow — if you need this exact bus protocol and timing, the MT55V512V32PT-5 is the part. For BOM planning, the 100TQFP footprint and 2.375 V supply are non-negotiable constraints. No alternative package or wider-temp variant is listed.
