WM72016-6
16Kbit Secure F-RAM Memory with Gen-2 RFID
Access & Serial Port Direct Memory Access
DESCRIPTION
FEATURES
The WM72016-6 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 WM72016-6 write
operations are zero power – there is no power or
speed premium paid for executing writes into the
WM72016-6 as compared to read power and speed.
Operation of the memory is fully symmetric: it has an
equivalent read and write range.
The WM72016-6‟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 WM72016-6 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.
