GENERAL DESCRIPTION
The DS28E01-100 combines 1024 bits of EEPROM with challenge-and-response authentication security implemented with the ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1). The 1024-bit EEPROM array is configured as four pages of 256 bits with a 64-bit scratchpad to perform write operations. All memory pages can be write protected, and one page can be put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. Each DS28E01-100 has its own guaranteed unique 64-bit ROM registration number that is factory lasered into the chip. The DS28E01-100 communicates over the single-contact 1-Wire® bus. The communication follows the standard Dallas Semiconductor 1-Wire protocol with the registration number acting as node address in the case of a multi-device 1-Wire network.

FEATURES
*1024 bits of EEPROM memory partitioned into four pages of 256 bits
*On-chip 512-bit SHA-1 engine to compute 160-bit Message Authentication Codes (MAC) and to generate secrets
*Write access requires knowledge of the secret and the capability of computing and transmitting a 160-bit MAC as authorization
*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")
*Communicates 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
*6-lead TSOC, 2-lead SFN or solder-bumped chipscale surface mount package

APPLICATIONS
*Printer Cartridge Configuration and Monitoring
*Medical Sensor Authentication and Calibration
*System Intellectual Property Protection

Product Description
 The CC2431 is a true System-On-Chip (SOC) for wireless sensor networking ZigBee™ / 802.15.4 solutions with location detection engine hardware onboard allowing location accuracy of around 3 meters or less. It enables ZigBee™ nodes to be built with very low total bill-of-material costs. The CC2431 combines the excellent performance of the leading CC2420 RF transceiver with an industry-standard enhanced 8051 MCU, 128 KB flash memory, 8 KB RAM and many other powerful features. Combined with the industry leading ZigBee™ protocol stack (Z-Stack™) from Figure 8 Wireless / Chipcon, the CC2431 provides the market’s most competitive ZigBee™ solution.

 The CC2431 is highly suited for systems where ultra low power consumption is required. This
is achieved by various operating modes. Short transition times between these modes further
ensure low power consumption.

Key Features
• Location Engine accurately calculates the location of a node in a network
• High performance and low power 8051 microcontroller core.
