Product details

2 Mbit async SRAM on a 70 ns bus — fit for byte-wide memory expansion

The Infineon CY62138CV33LL-70BAI is a 2 Mbit asynchronous SRAM from the MoBL series, organized as 256K x 8 bits.

Industrial temperature range and package — where it goes and what it takes to mount

The 36-TFBGA (7x7 mm) package is a fine-pitch BGA — not hand-solder territory. You'll need solder paste stencil, reflow profile, and X-ray inspection post-reflow to verify ball wetting. The 7x7 mm footprint saves board area versus a TSOP, but rework requires a hot-air station and careful alignment.

Lifecycle and compliance — active, but not RoHS

That matters if your assembly line is RoHS-only or if the final product must ship into EU RoHS jurisdictions without an exemption. For RoHS-required builds, you'd need to qualify an alternate finish or apply for an exemption.

Sourcing the CY62138CV33LL-70BAI — what to expect

Frequently asked questions

What is the exact memory size and organization of CY62138CV33LL-70BAI?

The CY62138CV33LL-70BAI is a 2 Mbit SRAM organized as 256K x 8 bits (byte-wide). It uses an asynchronous parallel interface.

What is the access time of CY62138CV33LL-70BAI?

The access time is 70 ns. That's the time from address change to valid data out. The write cycle time (word/page) is also 70 ns.

What are the recommended equivalent or replacement parts for CY62138CV33LL-70BAI?

For a faster 2 Mbit async SRAM in a similar footprint, the CY7C1011DV33-10BVXI offers 10 ns access time in a 48-VFBGA, but it is organized 128K x 16 (word-wide) — not a direct pin-for-pin swap. For a larger 4 Mbit option, the CY7C1041GE30-10ZSXI (256K x 16, 10 ns) or CY7C1041GN30-10BVXI (256K x 16, 10 ns) are alternatives with different organizations and packages. Verify your bus width and footprint before substituting.
