Technical Details & Description

12 ns access time — timing margin on the bus

The 12 ns access time defines how quickly data appears on the output after the address is stable.

Industrial temperature range — where it goes

The commercial-grade sibling would not hold calibration in those conditions.

Package and mounting: 28-SOJ surface-mount

The 28-SOJ package (0.300" body width, 7.62 mm) is a surface-mount JEDEC outline with J-bend leads. The Tube shipment is typical for engineering samples and small production runs; the same die is also available in Tape & Reel (CY7C1399BN-12VXIT) for automated pick-and-place.

Frequently asked questions

Can CY7C1399BN-12VXI work with 3.3V logic?

Yes — the supply voltage range is 3.0 V to 3.6 V, which directly matches a 3.3 V logic rail. The I/O levels are compatible with 3.3 V CMOS and LVTTL interfaces. It is not 5 V tolerant.
