DS28EC20  
20Kb 1-Wire EEPROM  
GENERAL DESCRIPTION  
FEATURES  
The DS28EC20 is a 20480-bit, 1-Wire® EEPROM  
organized as 80 memory pages of 256 bits each. An  
additional page is set aside for control functions.  
Data is written to a 32-byte scratchpad, verified, and  
then copied to the EEPROM memory. As a special  
feature, blocks of eight memory pages can be write  
protected or put in EPROM-Emulation mode, where  
bits can only be changed from a 1 to a 0 state. The  
DS28EC20 communicates over the single-conductor  
1-Wire bus. The communication follows the standard  
1-Wire protocol. Each device has its own unalterable  
and unique 64-bit ROM registration number. The  
registration number is used to address the device in  
a multidrop 1-Wire net environment.  
.
20480 Bits of Nonvolatile (NV) EEPROM  
Partitioned into Eighty 256-Bit Pages  
Individual 8-Page Groups of Memory Pages  
(Blocks) can be Permanently Write Protected or  
Put in OTP EPROM-Emulation Mode ("Write to 0")  
Read and Write Access Highly Backward-  
Compatible to Legacy Devices (e.g., DS2433)  
256-Bit Scratchpad with Strict Read/Write  
Protocols Ensures Integrity of Data Transfer  
200k Write/Erase Cycle Endurance at +25°C  
Unique Factory-Programmed 64-Bit Registration  
Number Ensures Error-Free Device Selection  
and Absolute Part Identity
