A 20 ns access time means the memory can complete a read or write cycle in 20 ns from address valid.
The CY7C027-20AXCT is marked Obsolete by Infineon (formerly Cypress). No last-time-buy window remains open through the manufacturer.

Frequently asked questions
Is CY7C027-20AXCT obsolete?
Yes, the CY7C027-20AXCT is marked Obsolete by Infineon (formerly Cypress). No manufacturer last-time-buy is available; supply is through the independent surplus channel.
What is a direct replacement for CY7C027-20AXCT?
No official Infineon successor order code is listed for the CY7C027-20AXCT. A pin-compatible replacement would need to be a 512Kbit dual-port asynchronous SRAM in a 100-TQFP (14x14) package with a 5 V supply and 20 ns or faster access time. Verify the mechanical footprint and timing against your design before committing.
What are the specifications of CY7C027-20AXCT?
The CY7C027-20AXCT is a 512Kbit dual-port asynchronous SRAM organized as 32K x 16, with a 20 ns access time, parallel interface, 4.5 V to 5.5 V supply, and commercial temperature range (0°C to 70°C). It comes in a 100-TQFP (14x14) package on Tape & Reel.
What is the package of CY7C027-20AXCT?
The CY7C027-20AXCT is supplied in a 100-TQFP package with a 14 mm x 14 mm body, surface-mount, on Tape & Reel.
