Product details

4 Mbit asynchronous SRAM for industrial bus-matched memory

The Infineon CY62146DV30L-55ZSXI is a 4 Mbit asynchronous SRAM from the MoBL (More Battery Life) series, organized as 256K x 16 bits with a parallel interface.

The 55 ns write cycle time is symmetric, so read-modify-write sequences do not stall.

Package and footprint: 44-TSOP II

Housed in a 44-TSOP II (0.400" body width, 10.16 mm), this surface-mount package is a common footprint for mid-density asynchronous SRAMs.

The MoBL series is Infineon's low-power asynchronous SRAM family, and the CY62146DV30L-55ZSXI remains a standard catalog item through independent distribution.

Frequently asked questions

When sourcing CY62146DV30L-55ZSXI, what's the closest functional second-source — CY7C1041GN30-10BVXI?

The CY7C1041GN30-10BVXI is a 4 Mbit asynchronous SRAM with the same 256K x 16 organization and 2.2 V supply, but it offers a 10 ns access time versus 55 ns. It is not a pin-compatible drop-in — the package is different (BGA vs TSOP). For a form-fit-function replacement in the same 44-TSOP footprint, the CY7C1041G30-10ZSXA is closer, though still 10 ns. If your system can tolerate 55 ns, the CY62146DV30L-55ZSXI is the correct fit.

What compliance documentation does this brand provide for CY62146DV30L-55ZSXI (RoHS, REACH, UL, IEC)?

The part is RoHS3 compliant. No REACH, UL, or IEC documentation is listed in the available records. For additional compliance certificates, request them with your RFQ.
