1Kb Single-Wire I/O Powered Serial EEPROM with a Unique, Factory Programmed 64-bit Serial Number

更多文档...

The Atmel® AT21CS11 Single-Wire device requires only two pins to access these devices: SI/O and GND. The SI/O signal is a combination data and power line, providing power to the device with a parasitic power scheme during the high time of the protocol sequence. This device includes a 64-bit unique Serial Number in every device, and with ESD tolerance to IEC 61000-4-2, this SI/O line can be directly accessed from outside the application. This device is ideally suited for the battery and battery charger market to achieve compliance with IEEE 1725 for battery parameter electronic identification. Additional application examples include analog sensor calibration and storage data, ink and toner print cartridge identification, and management of after-market consumables.

Product HighlightsBenefits

True 2-pin Device

  • Single data I/O pin and one ground pin needed
  • Device is over the data pin
  • Require only one pin from MCU/ASSP/MPU/ASIC
  • Smaller footprint, reduce PCB area and simplifies layout
  • Easy to integrate identification capability in consumables/cables

Ultra-low Standby and Active Current

  • 700nA typical standby current at 25C
  • 200µA typical write current at 25C
  • 80µA typical read current at 25C
  • Consumes at least one third less power in active mode then competition
  • Lowest energy consumption (increased battery life)
  • Enable high performance in low power applications with high speed mode

Follows I2C Protocol

  • Single-Wire interface with I2C protocol structure
  • Easy to migrate from existing I2C EEPROM
  • Lesser overhead and higher throughput
  • Capability to add up to 8 devices on same bus

Highest Level of ESD rating

  • IEC 61000-4-2 Level 4 ESD Compliant (±8kV Contact, ±15kV Air Discharge)
  • Able to tolerate SI/O being exposed to outside the application

Innovative memory architecture

  • Memory organized into four 256-bit zones
  • Tamper proof any 256-bit zone by permanently write protecting the data
  • Allows customers the flexibility to organize their data into different zones and permanently lock only the desired zones

Security Register (additional to 1Kb EEPROM)

  • 64-bit factory programmed serial number
  • Includes an extra 16-bytes of user programmable bytes
  • Serial number is guaranteed to be unique
  • Use the serial number for inventory tracking/asset tags
  • Program vital product data in the 16-byte section and permanently protect the data if desired
