Memory Type EEPROM

Memory Size 1K bits

Features 512-bit SHA-1 Engine
Five General-Purpose Read/Write Registers
Monetary
One 64-bit Write-Only Secret
Secure
Secure Hash Standard
Unique 64-bit Serial Number


* 1128 bits of 5V EEPROM memory partitioned into four pages of 256 bits, a 64-bit write-only secret and up to five general purpose read/write registers
   * Write access requires knowledge of the secret and the capability of computing and transmitting a 160-bit MAC as authorization
   * Secret and data memory can be write-protected (all or page 0 only) or put in EPROM-emulation mode ("write to 0", page 1)
   * On-chip 512-bit SHA-1 engine to compute 160-bit MAC and to generate secrets
   * Reads and writes over a wide voltage range of 2.8V to 5.25V from -40°C to +85°C
   * Communicates to host with a single digital signal at 14.1kb per second using 1-Wire protocol
   * On-chip 16-bit CRC generator for safeguarding data transfers
   * Overdrive mode boosts communication speed to 125kbps
   * Operating temperature range from -40°C to +85°C
   * Minimum 10 years of data retention at 85°C
