55 ns access time — what it means for bus timing
The 55 ns access time is the time from address valid to data valid on a read cycle. The write cycle time is also 55 ns. Because this is an asynchronous SRAM, there is no clock to synchronise — the controller strobes the chip enable and output enable directly. That simplifies the interface but puts the timing burden on the controller's address-to-data valid window.
Industrial temperature grade — -40°C to 85°C
Rated for -40°C to 85°C ambient, this part suits outdoor telecom cabinets, factory-floor PLCs, motor drives, and other equipment that sees temperature swings. It is not qualified for automotive under-hood (AEC-Q100) or extended industrial beyond 85°C, but the industrial range covers most commercial and light-industrial use cases.
Package and footprint — 32-SOIC wide-body
The 32-SOIC package has a body width of 0.445 inches (11.30 mm) — the wide-body variant. The supplier device package is listed as 32-SOIC.
Lifecycle and sourcing posture
The CY62148ELL-55SXIT carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, this means no near-term forced last-time-buy risk and normal lead times for volume orders. The part is actively specified into new designs where a 5V, 55 ns async SRAM with industrial temperature range is required.
