Preliminary

WM71004 / WM71008 / WM71016

4/8/16Kbit Secure F-RAM Memory with

Gen-2 RFID Access

DESCRIPTION

FEATURES

The WM710xx is a RFID transponder IC with

nonvolatile memory employing an advanced

ferroelectric process. A ferroelectric random access

memory, or F-RAM, is nonvolatile and performs

reads and writes like a RAM. It provides reliable data

retention for 20 years while eliminating the

complexities, overhead, and system level reliability

problems caused by EEPROM and other nonvolatile

memories.

4/8/16 Kbit Ferroelectric Nonvolatile RAM

•

Organized as 256/512/1024 x 16 bits

Very High Read/Write Endurance (> 10¹⁵)

20-Year Data Retention

Gamma Stability Demonstrated to > 30 kGy

Symmetric Read/Write Operation

Advanced High-Reliability Ferroelectric Process

Interface and Security Features

•

EPC Class 1 Gen2 (ISO18000-6C) RFID

Unlike EEPROM’s, the WM710xx write operations

are zero power – there is no power or speed premium

paid for executing writes into the WM710xx as

compared to read power and speed. Operation of the

memory is fully symmetric: identical read and write

characteristics in terms of power, speed, and

reliability.

Compliant Interface (revision 1.2.0)

192-Bit Memory: 96-Bit Electronic Product

Code™ (EPC), 32-Bit Access Password, 32-Bit

KILL Password, 64-Bit TID Memory (Factory

Programmed and Locked)

•

Inventory, Read, Write and Erase features

Kill Command

Block Permalock Command

The WM710xx’s RFID interface is compliant with

the EPC Class-1 Generation-2 UHF RFID Protocol

for Communications at 860 MHz – 960 MHz,

Version 1.2.0 Specification for RFID Air Interface.

Access Command

UHF carrier frequencies from 860 MHz to 960

MHz ISM band, ASK demodulation

Link frequencies up to 640Kbps and reader-to-

tag rates up to 128Kbps read and write

transmission

•

The WM710xx is a two chip configuration offered in

various forms: standard IC package or wafers. All

specifications discussed herein are applicable to the

combined chipset operation.

Custom Features

•

Stored Address Pointer to Improve Data Write
