For new designs or replacement, the pin-compatible CY7C027-15AXI (15 ns access time, same 100-TQFP footprint, same 5V supply and industrial temperature range) is a direct functional alternative — verify timing margin against your bus cycle before swapping. 20 ns access time and 20 ns write-cycle time let this dual-port SRAM keep up with a 25 MHz to 33 MHz shared-memory bus without wait states. The 32K x 16 organization gives a 16-bit-wide data path, common in DSP or dual-processor mailbox buffers. The 5V-only supply rail (4.5V min to 5.5V max) means no 3.3V operation — level translators are needed for mixed-voltage systems. ## Package and temperature — industrial, surface-mount Housed in a 100-TQFP (14x14 mm) body, surface-mount only.
