The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD).Low-Power CMOS Technology, Write current: 3 mA, typical, Read current: 500 μA, typical, Standby current: 500 nA, typical 8192 x 8 Bit Organization Self-Timed Erase and Write Cycles Block Write Protection, Protect none, 1/4, 1/2 or all of array Built-in Write Protection, Power on/off data protection circuitry, Write enable latch, Write-protect pin Sequential Read High Reliability, Data retention: > 200 years, ESD protection: > 4000V 8-pin PDIP, SOIC and TSSOP Packages Temperature Ranges Supported: Industrial (I): -40°C to +85°C, Automotive (E): -40°C to +125°C
