Product details

18 Mbit synchronous SRAM for high-speed parallel cache

The Infineon CY7C1386D-167AXCT is a 18 Mbit synchronous SRAM organized as 512K x 36, clocked at 167 MHz with a 3.4 ns access time. The 36-bit wide data bus suits designs that carry parity or ECC alongside the data word — common in networking line cards, telecom switch fabrics, and high-end cache buffers where the extra width avoids a second memory bank.

Commercial temperature range — indoor equipment only

This limits deployment to controlled environments.

Frequently asked questions

What is the replacement for CY7C1386D-167AXCT?

No official replacement order code is listed in the lifecycle record. For a pin-compatible alternative, check the CY7C1386D base family for other speed or package variants that may still be active, or contact us with your requirements for a cross-reference search.

Where can I buy CY7C1386D-167AXCT?

The CY7C1386D-167AXCT is obsolete but can be sourced to order against an RFQ through our independent distribution network. Submit an RFQ for current availability and pricing.

What are the specifications of CY7C1386D-167AXCT?

The CY7C1386D-167AXCT is an 18 Mbit synchronous SDR SRAM organized as 512K x 36, with a 167 MHz clock frequency, 3.4 ns access time, parallel interface, 3.135 V to 3.6 V supply, and a 0°C to 70°C operating temperature range. It comes in a 100-TQFP (14x20 mm) package on tape and reel.

What is the difference between CY7C1386D-167AXCT and CY7C1386D-167AXC?

The CY7C1386D-167AXCT and CY7C1386D-167AXC share the same die and speed grade. The difference is the packaging format: the 'CT' suffix indicates tape-and-reel (TR), while the 'XC' suffix typically denotes a tray or tube shipping format. The electrical specifications are identical.
