Frequently asked questions
What is the direct replacement or cross-reference for this SRAM?
The CY7C1570KV18-500BZC is the most natural cross-reference: same 72Mbit density, same 2M × 36 organization, same 1.7 V supply, same 165-FBGA package. It runs at 500 MHz versus 375 MHz, which is a faster speed grade — not a slower one. A layout designed for the 375 MHz part will accept the 500 MHz part at rated speed without a board respin, though the host firmware timing parameters may need adjustment for the higher clock rate.
Can the CY7C1550KV18-400BZC substitute for the CY7C1570V18-375BZC?
Physically the packages are identical. The C1550 base product differs from C1570 at the die level, and the memory controller may require part-family-specific configuration — firmware may need a speed-derate flag or register adjustment to run below the 400 MHz ceiling without violating setup/hold margins at the system clock. Verify with the controller datasheet before substituting.
