Asynchronous SRAM for 16-bit data bus designs
The CY62126DV30LL-55BVI is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits, so it maps directly onto a 16-bit data bus without byte-lane muxing — a clean fit for MCUs and DSPs that expect a 16-bit wide external memory interface. With a 55 ns access time, the part supports read cycles down to that period; the write cycle time (word, page) is also 55 ns, matching the read speed for symmetric bus timing.
Package and board integration
Housed in a 48-VFBGA (6 x 8 mm) — a fine-pitch BGA that demands a controlled reflow profile and a multi-layer PCB for fan-out of the 48 balls. The supplier device package is 48-VFBGA (6x8), so the footprint matches that exact body size. Supplied in Bulk (not tape-and-reel), which is typical for engineering samples or low-volume production runs — the buyer should confirm tray or tube format at RFQ if pick-and-place handling is planned.
RoHS non-compliant per the manufacturer's declaration — the part contains lead (Pb) above the exemption threshold. For EU or RoHS-mandated markets, verify whether a Pb-free equivalent (e.g., the -55ZXI suffix variant) is acceptable before committing the BOM.
