GX28E01-100 GXCAS Datasheet

GX28E01-100 Key Features

• 1024 bits of EEPROM memory partitioned into four pages of 256 bits
• On-chip 512-bit SHA-1 engine to pute 160-bit Message Authentication Codes (MAC) and to generate secrets
• Write access requires knowledge of the secret and the capability of puting and transmitting a 160-bit MAC as authorizati
• User-programmable page write-protection for page 0, page 3 or all four pages together
• User-programmable OTP EPROM emulation mode for page 1 ("write to 0")
• municates to host with a single digital signal at 15.3k bits or 125k bits per second using 1-Wire protocol
• Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
• Reads and writes over a wide voltage range of 2.8V to 5.25V from -40°C to +85°C
