CAT34AC02
2K-Bit SMBus EEPROM for ACR Card Configuration
FEATURES
DESCRIPTION
The CAT34AC02 is a 2K-bit Serial CMOS EEPROM
internally organized as 256 words of 8 bits each. Catalyst’s
advanced CMOS technology substantially reduces de-
vice power requirements. The CAT34AC02 features a

... A maximum of eight devices can be cascaded when using the device. WP: Write Protect This input, when tied to GND, allows write operations to the entire memory. For CAT34AC02 when this pin is tied the entire array of memory is write protected. CC When left floating, memory is unprotected. ...

... WRITE PROTECTION The write protection feature of CAT34AC02 allows the user to protect against inadvertent programming of the memory array. If the WP pin is tied to Vcc, the entire memory array is protected and becomes read only. If the WP pin is left floating or tied to Vss, the device can be written into. ...
