1Mbit parallel SRAM for industrial bus-interface designs
The Infineon CY62126DV30LL-55ZXI is a 1Mbit parallel SRAM organized as 64K x 16 bits.
55 ns access time — timing margin for the bus
The write cycle time matches the read access at 55 ns.
There is no pending PCN or last-time-buy window to track.
Surface-mount in a 44-pin TSOP II package. The footprint is standard for this density class; the pinout matches other 64K x 16 SRAMs from Infineon and Cypress, simplifying a drop-in swap during board re-spin. No heatsinking required — the package dissipates well within its thermal limits at the rated temperature range.
