Product details

What this dual-port SRAM does on the board

The Infineon CY7C0832BV-133AI is a 4.5 Mbit synchronous dual-port SRAM organized as 256K x 18 bits. The 133 MHz clock lets both ports access memory without wait states, and the supply runs on 3.135 V to 3.465 V at -40°C to 85°C.

Obsolete — sourcing reality for this SRAM

No last-time-buy window remains open from the factory. No official pin-compatible successor is listed by Infineon for this exact speed grade; any substitution would require a board respin or a slower/faster variant that may not match the timing closure.

The part comes in a 120-lead LQFP (14x14 mm body) — surface-mount, tray delivery.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C0832BV-133AI?

Infineon does not list an official pin-compatible successor for this exact speed grade. Any replacement would require verifying timing and density compatibility; a board respin may be needed.

What is CY7C0832BV-133AI's package?

The device is supplied in a 120-lead LQFP (14x14 mm) on tray.

What is CY7C0832BV-133AI's memory technology?

It is a synchronous dual-port SRAM — volatile memory with a parallel interface.
