Product details

Industrial temperature grade

Rated for -40°C to 85°C ambient, the BZXI suffix covers outdoor telecom cabinets and factory-floor control enclosures where the commercial-grade CY7C25632KV18-550BZC (0°C to 70°C) would risk timing margin above 70°C. If the BOM targets an unconditioned environment, this is the variant to lock in.

Infineon lists this part as Active, meaning the manufacturer continues to accept new orders and support production builds. No last-time-buy window is announced. The 165-FBGA (13x15 mm) footprint matches the commercial-temperature BZC variant, so a qualification swap between the two is a BOM-line change, not a board respin.

Frequently asked questions

Will CY7C25632KV18-550BZXI drop into a board designed for CY7C25632KV18-550BZC?

Yes, both share the same 165-FBGA (13x15 mm) package and pinout. The BZXI variant adds the -40°C to 85°C industrial temperature range; the BZC is 0°C to 70°C. No board respin needed for the swap.

What is the closest functional second-source for CY7C25632KV18-550BZXI?

The CY7C25632KV18-400BZXI is the same density and organization but runs at 400 MHz. For a full-speed drop-in, the CY7C25632KV18-550BZC is pin-compatible but commercial-temperature only. No exact second-source from another manufacturer is listed.
