17 ns access time and write cycle time. Supports back-to-back writes at the same rate.

Obsolete per manufacturer lifecycle. No official successor listed. Sourced to order against RFQ through independent distribution.

5 V supply and commercial temperature grade

4.5 V to 5.5 V supply range. 0°C to 70°C commercial temperature grade. 36-SOJ surface-mount package.

Frequently asked questions

Is CY7C1049BNL-17VCT obsolete?

Yes, the CY7C1049BNL-17VCT is obsolete per the manufacturer's lifecycle status. No official successor is listed. Stock is available through surplus and independent distribution channels, sourced to order against an RFQ.

What is the replacement for CY7C1049BNL-17VCT?

No official replacement order code is documented in the lifecycle record. For a pin-compatible alternative, look for a 5 V asynchronous SRAM in a 36-SOJ package with 512K x 8 organization and 17 ns or faster access time from a manufacturer still active in that form factor. Confirm the footprint and timing before substituting.

What are the electrical specifications of CY7C1049BNL-17VCT?

The CY7C1049BNL-17VCT is a 4 Mbit (512K x 8) asynchronous SRAM with a 17 ns access time, parallel interface, operating from 4.5 V to 5.5 V over 0°C to 70°C. The write cycle time is also 17 ns.
