Additional Details

The CY14B104L-BA25XC utilizes Cypress's nvSRAM technology, which combines a standard SRAM cell with a nonvolatile storage element. During normal operation, the device functions as a standard SRAM, providing fast read and write access. When power is lost, the data in the SRAM is automatically transferred to the nonvolatile memory, ensuring data retention. Upon power restoration, the data is automatically transferred back to the SRAM. This automatic data protection mechanism ensures data integrity without requiring any external intervention.

The device is available in various package options and temperature grades to meet different application requirements. It is designed for applications where data integrity and reliability are paramount, making it an ideal choice for critical systems.
