DS28CZ04  
4kbit I²C/SMBus EEPROM  
with Nonvolatile PIO  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS28CZ04 combines 4kbit (512 x 8) EEPROM  
with 4 PIO lines. Communication with the device is  
accomplished with an industry standard I²C* and  
SMBus™ interface. The memory is organized as two  
segments of 256 bytes with single byte and up to 16-  
byte block write capability. Individual PIO lines may  
be configured as inputs or outputs. The power-on  
state of PIO programmed as outputs is stored in non-  
volatile memory. All PIO may be reconfigured by the  
user through the serial interface.  
Cꢀ 4kbit (512x8) EEPROM Organized in Two 256-  
Byte Blocks  
Cꢀ Single Byte and up to 16-Byte EEPROM Write  
Sequences  
Cꢀ Write-Protect Control Pin for the Entire EEPROM  
Array  
Cꢀ Endurance 200k Cycles per Block at 25°C; 10ms  
max EEPROM Write Cycle  
Cꢀ 4 PIO Lines  
Cꢀ Each PIO is Configured to Input or Output Mode  
on Startup by Stored Value  
Cꢀ All PIOs are Reconfigurable after Startup  
Cꢀ Serial Interface User-Programmable for I²C Bus  
and SMBus Compatibility  
APPLICATIONS  
Sꢀ 4G SFP Copper Modules  
Sꢀ SFF-8472, SFP Fiber Modules  
Sꢀ RAID Systems  
Cꢀ Supports 100kHz and 400kHz I²C Communica-  
tion Speeds  
Cꢀ Operating Range: 2.0V to 5.25V, -40°C to +85°C  
Cꢀ 4mm x 4mm 12-Pin TQFN Package
