Write cycle time is also 70 ns, so the same timing budget applies to write operations — the word and page write modes share this ceiling, meaning a page-mode burst does not accelerate the write cycle itself, only the address sequencing between writes. ## 128K x 8 organization and the 5 V supply rail Organised as 128K words of 8 bits, the CY62128BNLL-70SI presents a byte-wide data bus — it maps directly to an 8-bit microcontroller or a discrete address/data bus without byte-lane steering logic. ## Industrial temperature grade and the 32-SOIC footprint Housed in a 32-SOIC wide-body package (0.445-inch body width, 11.30 mm), the footprint is the standard JEDEC 300-mil SOIC-32 — the same pad pattern used by legacy 32-pin SRAMs and EEPROMs, so a board already routed for a 32-SOIC memory accepts this part without a layout change. ## Active lifecycle and the RoHS flag The part is marked RoHS non-compliant, meaning the lead-frame finish or mould compound contains lead above the RoHS exemption thresholds — if your assembly line or end-customer requires full RoHS compliance (e.g. for EU market or green-label products), this part does not meet that requirement and a Pb-free variant should be sourced.","metaTitle":"Infineon CY62128BNLL-70SI MoBL SRAM, 1Mbit, 70 ns, 32-SOIC","metaDescription":"Infineon CY62128BNLL-70SI MoBL asynchronous SRAM, 1Mbit (128K x 8), 70 ns access, 4.5-5.5 V, -40 to 85°C.
