Serial Peripheral Interface compatible (SPI bus)
SPI mode 0 (0,0), 3 (1,1)
Clock frequency: 5 MHz (2.5 V to 5.5 V), 3 MHz (1.8 V to 5.5 V)
Power dissipation:
Standby: 2µA (max)
Active (Read): 3.0 mA (max)
Active (Write): 3.5 mA (max)
Automatic page write: 32-byte/page
Write cycle time: 5 ms
Endurance: 106 Erase/Write Cycles
Data retention: 10 Years
Small size packages: SOP-8pin, TSSOP-8pin
Shipping tape and reel
TSSOP-8pin : 3,000 IC/reel
SOP-8pin : 2,500 IC/reel
Temperature range: 40 to +85°C
