CY15B064Q-SXET

• 64 Kbit F-RAM (ferroelectric RAM) Nonvolatile Memory
• Organized 64Kb X 8, 8-Bit Data Bus
• 3.3 V Operating supply, Up to 16 MHz
• Nonvolatile Writes at Bus Speed with No Erase Cycle or Write Delay
• 8-Pin SOIC package, Asynchronous Access
• -40°C to 125°C Extended temperature; RoHS Status: Non-Compliant for This Option

The Infineon CY15B064Q-SXET is a 64 Kbit ferroelectric RAM (F-RAM) nonvolatile memory organized as 64Kb x 8, operating from a 3.3 V supply at up to 16 MHz in an 8-pin SOIC package. F-RAM writes at bus speed with no write delay and no erase cycle, unlike EEPROM or flash, so data is committed as soon as the transaction completes. The CY15B064Q-SXET is rated for the extended -40°C to 125°C range and ships on tape and reel; note this ordering option is flagged RoHS non-compliant.

F-RAM is selected over EEPROM when a design has to write nonvolatile data frequently or must guarantee that the last write survives an abrupt power loss, since there is no page-program delay to complete. That makes it the standard part for utility and industrial meters holding cumulative readings, motion and servo controllers storing position, data loggers writing at high rates, and any system that must record state during a brownout. The 125°C rating supports enclosed, high-ambient installations. Typical buyers are metering, industrial automation, medical device, and automotive OEMs and their contract manufacturers; the non-RoHS status limits this specific ordering option to applications with an appropriate exemption or non-EU market.
