Ramtron beta samples wireless memory product
A Ramtron International product story
Edited by the Electronicstalk editorial team Oct 7, 2009
Ramtron International 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 range is suitable for applications in industries including aircraft/industrial manufacturing, inventory control, maintenance tracking, building security, electronic toll collection, pharmaceutical tracking and product authentication.
Production of WM710xx family is scheduled to begin in the first quarter of 2010.
Ramtron's first family of MaxArias wireless memory combines up to 16Kb of nonvolatile F-RAM memory with EPCglobal Class-1 Generation-2 UHF Air Interface Protocol Standard, operating at 860-960MHz.
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 offer 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 at the maximum data rates allowed by the Gen-2 standard.
