Product details

12 ns async SRAM — 512Kbit in a 44-SOJ footprint

The Infineon CY7C1020BN-12VXCT is a 512Kbit asynchronous SRAM organised as 32K x 16 bits, with a 12 ns access time that matches fast bus cycles without wait states in 5V logic systems. The 44-SOJ (BSOJ) package with J-leads is a surface-mount footprint that was common on mid-1990s through 2000s designs — still findable on repair or retrofit BOMs.

Infineon (formerly Cypress Semiconductor) lists the CY7C1020BN-12VXCT as Obsolete. No last-time-buy window remains open from the factory.

5V supply, commercial temperature — deployment context

Not rated for automotive, outdoor, or extended-temperature industrial use.

Package and mounting — 44-SOJ on Tape & Reel

The 44-SOJ (Small Outline J-lead) package has a 0.400-inch (10.16 mm) body width. Surface-mount only — no through-hole variant. The J-lead form factor gives a smaller footprint than a SOIC but requires a specific solder-paste stencil aperture for reliable wetting.

Frequently asked questions

Where can I buy CY7C1020BN-12VXCT?

This part is obsolete from the manufacturer. We source CY7C1020BN-12VXCT through independent distribution and verified surplus inventory. Submit an RFQ for current availability and pricing — quotes are confirmed at order time with traceable stock.

Is CY7C1020BN-12VXCT obsolete?

Yes, Infineon lists the CY7C1020BN-12VXCT as Obsolete. No factory last-time-buy remains active. Supply is limited to existing surplus and broker-channel inventory.

What is the replacement for CY7C1020BN-12VXCT?

Infineon does not publish a direct drop-in replacement for this specific order code in the current evidence. For a functionally equivalent 512Kbit async SRAM with 12 ns access in a 44-SOJ or compatible footprint, cross-reference the base part number CY7C1020 family or contact us with your board's supply voltage and temperature requirements — we can quote an active alternative against your BOM.
