70 ns access — timing margin for the bus
The 70 ns access time governs how quickly data appears on the bus after the address is valid. The write cycle time matches at 70 ns, so read and write latencies are symmetric.
Industrial temperature grade and package
Rated for -40°C to 85°C, this SRAM handles the thermal swing of outdoor telecom cabinets, factory-floor PLC enclosures, and engine-bay-adjacent electronics without derating. The 28-TSOP I surface-mount package (11.80 mm body width) fits a standard SOIC footprint on a two-layer board; the 0.465-inch (11.80 mm) width is the key dimension for PCB layout clearance.
RoHS status — note the non-compliant flag
The CY62256LL-70ZRIT is marked RoHS non-compliant. If your BOM requires lead-free assembly or your customer mandates RoHS conformance for the end product, this part does not meet that requirement. The non-compliant status applies to the entire order code; verify your internal exemptions or plan for a separate process flow.
Lifecycle and sourcing posture
This part carries an Active lifecycle status, so there is no last-time-buy or obsolescence risk for current production runs. For volume commitments, the active status means Infineon continues to manufacture the die, and the independent channel provides flexible lot sizes without factory MOQ pressure.
