WM72016

16Kbit Secure F-RAM Memory with Gen-2 RFID

Access & Serial Port Direct Memory Access

DESCRIPTION

The WM72016 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.

Unlike EEPROM‟s, the WM72016 write operations

are zero power – there is no power or speed premium

paid for executing writes into the WM72016 as

compared to read power and speed. Operation of the

memory is fully symmetric: it has an equivalent read

and write range.

The WM72016‟s RFID interface is compatible 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.

The WM72016 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.
