DESCRIPTION

· The bq4017 is a CMOS nonvolatile 16,777,216-bit static RAM organized as 2,097,152 words by 8 bits.

· It integrates control circuitry and a lithium energy source for reliable nonvolatility with unlimited write cycles.

· The device monitors the 5V supply and activates write-protection and the backup energy source during power anomalies.

FEATURES

· Data retention without power for a minimum of 5 years.

· Automatic write-protection during power-up/power-down cycles.

· Operates like conventional SRAM with unlimited write cycles.

· Battery is internally isolated until power is applied.

APPLICATIONS

· Suitable for systems requiring reliable nonvolatile memory with fast access times.

· Ideal for applications where data integrity is critical during power transitions.

· Can be used in environments where long-term data retention is necessary without continuous power supply.
