CAT24C44SI-TE13 Datasheet PDF - Catalyst

●DESCRIPTION

●The CAT24C44 Serial NVRAM is a 256-bit nonvolatile memory organized as 16 words x 16 bits. The high speed Static RAM array is bit for bit backed up by a nonvolatile EEPROM array which allows for easy transfer of data from RAM array to EEPROM (STORE) and from EEPROM to RAM (RECALL). STORE operations are completed in 10ms max. and RECALL operations typically within 1.5µs. The CAT24C44 features unlimited RAM write operations either through external RAM writes or internal recalls from EEPROM. Internal falsestore protection circuitry prohibits STORE operations

●when VCC is less than 3.5V (typical) ensuring EEPROM data integrity.
