Ramtron International has announced that it has begun beta sampling its first MaxArias wireless memory product to customers across several industries.

Ramtron’s MaxArias wireless memory combines the low-power, high-speed and high-endurance features of Ramtron’s nonvolatile F-RAM memory technology with wireless access, to enable data collection capabilities for a range of applications.

Ramtron’s first family of wireless memory devices, named the MaxArias WM710xx product line, features F-RAM memory with passive UHF EPCglobal Class-1 Generation-2 wireless access in a transponder IC with 4-, 8-, and 16Kb user memory densities.

The WM710xx family is suitable for applications in industries including aircraft/industrial manufacturing, inventory control, maintenance tracking, building security, electronic toll collection, pharmaceutical tracking and product authentication.

Ramtron’s first family of MaxArias wireless memory combines up to 16Kb of high-performance, nonvolatile F-RAM memory with EPCglobal Class-1 Generation-2 UHF Air Interface Protocol Standard, operating at 860MHz to 960MHz.

When combined with an optimised antenna design, the MaxArias WM710xx product family powers up with energy harvested directly from the RF field.

As specified in the Gen-2 standard, the MaxArias chip receives and processes commands transmitted by the RFID reader.

The first MaxArias wireless memory devices – WM71004, WM71008 and WM71016 – are organised as 256/512/1024 x 16 bits, respectively.

The devices have virtually unlimited read/write endurance of 1E14 (100 trillion) writes and 20-year data retention.

MaxArias wireless memory offers fully symmetrical operation for reads and writes in terms of range, sustained memory access bandwidth and reliability – all at the maximum data rates allowed by the Gen-2 standard.

Ramtron’s MaxArias wireless memory offers benefits over traditional Eeprom-based, RF-enabled ICs.

The WM710xx write operations are zero power, resulting in no power or speed penalty for executing writes.

The low power F-RAM-enabled MaxArias wireless memory provides symmetrical wireless reads/writes at 10m or more.

With speeds up to six times faster than Eeprom, MaxArias wireless memory enables full memory block-write operations, allowing more data to be stored faster without the required soak time of Eeprom-based devices.

Data integrity is ensured with Ramtron’s SureWrite feature that prevents data corruption during full block-writes.

Due to F-RAM’s invulnerability to magnetic fields and high tolerance to gamma radiation, the MaxArias wireless memory is suitable for applications subject to magnetic or irradiating fields.

The MaxArias WM710xx wireless memory operates over the industrial temperature range -40 to 85C.

The WM710xx will be offered in several configurations: a standard green RoHS-compatible six-pin UDFN package, bumped wafer, bare dice, or as a fully tested ISO-18000-6C compliant transponder antenna inlay.
