8-Kb and 16-Kb SPI Serial
CMOS EEPROM
Description
The CAV25080/25160 are 8−Kb/16−Kb Serial CMOS EEPROM
devices internally organized as 1024x8/2048x8 bits. They feature a
32−byte page write buffer and support the Serial Peripheral Interface
(SPI) protocol. The device is enabled through a Chip Select (CS)
input. In addition, the required bus signals are a clock input (SCK),
data input (SI) and data output (SO) lines. The HOLD input may be
used to pause any serial communication with the CAV25080/25160
device. These devices feature software and hardware write protection,
including partial as well as full array protection.
Features
• Automotive Temperature Grade 1 (−40°C to +125°C)
• 10 MHz SPI Compatible
• 2.5 V to 5.5 V Supply Voltage Range
• SPI Modes (0,0) & (1,1)
• 32−byte Page Write Buffer
• Self−timed Write Cycle
• Hardware and Software Protection
• Block Write Protection
− Protect 1/4, 1/2 or Entire EEPROM Array
• Low Power CMOS Technology
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• Industrial and Extended Temperature Range
• 8−lead SOIC and TSSOP Packages
• These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
