Product details

The Infineon CY15B064J-SXE is a 64Kbit ferroelectric RAM (FRAM) organized as 8K x 8, accessed over an I²C bus at up to 1 MHz. The non-volatile storage combines the write endurance of RAM (essentially unlimited) with the data retention of EEPROM, making it a drop-in for parameter logging, calibration tables, and fault-recording buffers in engine ECUs, transmission controllers, and ADAS sensor modules. Supply range is 3V to 3.6V, matching common 3.3V rail designs.

No last-time-buy or NRND notice applies. It is ROHS3 compliant. The AEC-Q100 qualification is factory-documented; no separate screening or lot acceptance is needed for automotive PPAP submissions. The package is 8-SOIC (3.90 mm body width), surface-mount, shipped in tube.

Frequently asked questions

Does CY15B064J-SXE have lead-free and RoHS compliance?

Yes, the CY15B064J-SXE is ROHS3 compliant. It is lead-free and meets the latest RoHS directive requirements.

Can CY15B064J-SXE replace an EEPROM like 24AA64?

Yes, the CY15B064J-SXE is a 64Kbit I²C non-volatile memory that can replace a 24AA64 EEPROM in most designs. The FRAM technology offers essentially unlimited write endurance versus the ~1 million cycles of EEPROM, and writes at bus speed without the write-cycle delay. The supply range (3V to 3.6V) and I²C interface are compatible. Verify the pinout and package (8-SOIC) match your layout.
