The 45 ns access time sets the read-cycle floor: a processor with a bus clock above about 22 MHz will need wait states unless the memory controller can stretch the cycle. For a 16-bit MCU running at 16–20 MHz, this part can usually keep up with zero wait states, which saves the latency penalty of a slower asynchronous SRAM. The 2.2 V supply rail aligns with low-voltage core domains — handy when the board already runs a 1.8 V or 2.5 V logic supply and you want to avoid a separate 3.3 V regulator for the SRAM. That said, the 45 ns speed grade and the 48-VFBGA package are not the highest-volume variants in the MoBL family — if you're planning a multi-year production run, it's worth confirming the supply window with your distributor. ## Package and footprint — 48-VFBGA The 48-VFBGA (Very Fine-Pitch Ball Grid Array) package is a 6 x 8 mm body with 0.5 mm ball pitch. That pitch rules out hand-assembly without a stencil and reflow oven; rework needs a hot-air station with a fine nozzle and a good alignment fixture. Decouple with a 0.1 µF ceramic per supply pin, placed as close to the balls as the board allows.","metaTitle":"Cypress CY62157EV30LL-45BVXA 8Mbit SRAM, 45 ns, 48-VFBGA","metaDescription":"Cypress MoBL® CY62157EV30LL-45BVXA 8Mbit (512K x 16) parallel SRAM, 45 ns access time, 2.2 V supply, -40°C to 85°C, 48-VFBGA.
