– Read access times: 90, 120, or 150 ns (depending on version)
– Low power consumption:
Active mode: up to 25 mA
Standby mode: up to 100 µA
– Simple write operation:
Internal address and data latches
Self-timed write cycle with auto-clear
– Fast write cycle: maximum 5 ms
– Compatibility: CMOS and TTL-compatible inputs and outputs
– Write protection: both hardware and software protection available
– Automatic page write operation: 1 to 32 bytes in 5 ms
– End-of-write detection: via data polling and toggle bits
– Endurance: up to 100,000 program/erase cycles
– Data retention: up to 100 years
