Product details

32K x 16 asynchronous SRAM, 15 ns access

The CY7C1020BN-15ZXCT: This is a 512Kbit (32K x 16) asynchronous SRAM with a 15 ns access time. The parallel interface and 4.5V-5.5V supply rail place it in the 5V legacy SRAM class — a direct fit for existing BOMs that cannot migrate to a lower-voltage memory without a board spin.

44-TSOP II — surface-mount legacy footprint

The 0.8 mm pin pitch is reworkable with a hot-air station — no BGA underfill or X-ray inspection needed. Operating temperature is commercial grade: 0°C to 70°C.

Frequently asked questions

Is CY7C1020BN-15ZXCT obsolete?

Yes, Infineon lists the CY7C1020BN-15ZXCT as Obsolete. It is no longer manufactured or stocked by the factory.

Does CY7C1020BN-15ZXCT have a 5V supply?

Yes, the supply voltage range is 4.5V to 5.5V. This is a 5V nominal part — not compatible with a 3.3V-only memory bus without a level translator.

What is the memory organization of CY7C1020BN-15ZXCT?

Organized as 32K words by 16 bits (32K x 16), giving a total density of 512Kbit. The 16-bit data bus is parallel, not serial.

Where can I buy CY7C1020BN-15ZXCT?

Available through independent distribution — sourced to order against an RFQ. Since the part is obsolete, availability is lot-specific and confirmed at quote time. Submit an RFQ for current pricing and date-code options.
