Specifications of CAV25160VE-GT3

Product Category
EEPROM
CAV25080, CAV25160
8-Kb and 16-Kb SPI Serial
CMOS EEPROM
Description
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.

The CAV25080/160 device powers up into a write disable state. The device contains a Write Enable Latch (WEL) which must be set before attempting to write to the memory array or to the status register. In addition, the address of ...

Page 7

Byte Write Once the WEL bit is set, the user may execute a write sequence, by sending a WRITE instruction, a 16−bit address and data as shown in Figure 5. Only 10 significant address bits are used by the CAV25080 ...

Write Status Register The Status Register is written by sending a WRSR instruction according to timing shown in Figure 7. Only bits 2, 3 and 7 can be written using the WRSR command SCK OPCODE ...
