Product details

The Infineon (formerly Cypress) CY7C1021CV33-8VXCT is a 1Mbit asynchronous SRAM organized as 64K x 16 bits. It operates from a 3.0 V to 3.6 V supply and delivers an 8 ns access time, making it suitable for cache, buffer, and scratchpad memory in networking, telecom, and embedded systems where fast random access is needed. The part is in a 44-SOJ surface-mount package and is rated for commercial temperature (0°C to 70°C), limiting it to indoor, temperature-controlled equipment.

Commercial temperature grade — deployment limits

This part belongs in office equipment, indoor telecom racks, test gear, and consumer electronics. Not suitable for engine bays, outdoor base stations, or factory-floor cabinets without active climate control.

Frequently asked questions

Is CY7C1021CV33-8VXCT obsolete?

Yes, the CY7C1021CV33-8VXCT is officially obsolete. There is no active last-time-buy from the manufacturer. Sourcing is via independent distribution — new-old-stock or surplus — quoted to order against an RFQ.

What is the replacement for CY7C1021CV33-8VXCT?

Infineon does not list a direct pin-compatible active successor. A cross-reference to a current 1Mbit async SRAM in a 44-SOJ package from another vendor (e.g., ISSI, Renesas) would require verifying the pinout, timing, and supply voltage against the original design.

Where can I buy CY7C1021CV33-8VXCT?

This obsolete SRAM is sourced through independent distribution channels. Submit an RFQ for current availability and pricing — confirmed at quote time, no stock or price figures listed here.

What is CY7C1021CV33-8VXCT's package and temperature range?

The part is in a 44-SOJ surface-mount package and rated for 0°C to 70°C commercial temperature range.
