CAT25320
32-Kb SPI Serial CMOS
EEPROM
Description
The CAT25320 is a 32−Kb Serial CMOS EEPROM device
internally organized as 4096x8 bits. This features a 32−byte page write
buffer and supports the Serial Peripheral Interface (SPI) protocol. The
device is enabled through a Chip Select (CS) input. In addition, the
required bus signals are clock input (SCK), data input (SI) and data
output (SO) lines. The HOLD input may be used to pause any serial
communication with the CAT25320 device. The device features
software and hardware write protection, including partial as well as
full array protection.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The DC input voltage on any pin should not be lower than −0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than −1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.

6. tWC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle.
7. All Chip Select (CS) timing parameters are defined relative to the positive clock edge (Figure 2). tCSH timing specification is valid
for die revision C and higher. The die revision C is identified by letter “C” or a dedicated marking code on top of the package. For
previous product revision (Rev. B) the tCSH is defined relative to the negative clock edge.
