Last Buy — plan the LTB now
Infineon has placed the CY7C1021CV33-12ZSXE into Last Buy status. That means the manufacturer has a final purchase window open, after which this exact order code will no longer be produced. For sustainment programs — medical, defense, industrial controls — this is the trigger to either place a lifetime buy or qualify a form-fit-function alternative.
Access time is 12 ns. Write cycle time also 12 ns.
The 125°C ceiling covers the junction temperature in a sealed enclosure with limited airflow. If your design stays in a conditioned lab or office, the commercial-grade sibling would save cost, but for field-deployed hardware this temperature range is the right call.
