Device identity and key parametrics
The CY62256V-70SNCT is a 256Kbit (32K x 8) parallel SRAM from Infineon's MoBL® series, packaged in a 28-SOIC surface-mount package. As a volatile memory, data is retained only while power is applied, making it suitable for high-speed cache or buffer applications where the bus interface is parallel and the system controller manages refresh via the chip enable.
Temperature grade and operating envelope
The 70 ns access time sets the read cycle ceiling — the system bus must allow for the address-to-data valid delay plus the output hold time when back-to-back reads are required.
Infineon lists the CY62256V-70SNCT as Active, meaning the manufacturer continues to support new designs and production orders.
