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. It runs on a 3V to 3.6V supply and presents a 70 ns access time on a parallel interface.
Industrial temperature range and package — where it goes and what it takes to mount
Rated for -40°C to 85°C ambient (industrial grade), this SRAM is comfortable in outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics that see temperature swings. 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
It's suitable for new designs and ongoing production runs. 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
This SRAM is sourced through independent distribution and quoted to order against an RFQ. For a BOM line that needs this exact 2 Mbit x8 async SRAM in the 36-TFBGA footprint, the CY62138CV33LL-70BAI is the direct fit.
