MAXIM DS28E01P-100  DS28E01P 1K-Bit Protected 1-Wire EEPROM

PDF Datasheet：

FEATURES 

ƒ 1024 bits of EEPROM memory partitioned into 

four pages of 256 bits 

ƒ On-chip 512-bit SHA-1 engine to compute 160-bit 

Message Authentication Codes (MAC) and to 

generate secrets 

ƒ Write access requires knowledge of the secret 

and the capability of computing and transmitting 

a 160-bit MAC as authorization 

ƒ User-programmable page write-protection for 

page 0, page 3 or all four pages together 

ƒ User-programmable OTP EPROM emulation 

mode for page 1 ("write to 0") 

ƒ Communicates to host with a single digital signal 

at 15.3k bits or 125k bits per second using 

1-Wire protocol 

ƒ Switchpoint Hysteresis and Filtering to Optimize 

Performance in the Presence of Noise 

ƒ Reads and writes over a wide voltage range of 

2.8V to 5.25V from -40°C to +85°C 

ƒ 6-lead TSOC, 2-lead SFN or solder-bumped 

chipscale surface mount package
