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

更多文档...

The Atmel® AT21CS01 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. 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 powered via 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 EERPOM
  • 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
