EM4325
18000-63 Type C (Gen2) and
18000-63 Type C / 18000-64 Type D (Gen2/TOTAL) RFID IC
Description
Features
EM4325 is a Class-3 Generation-2 (Gen2) IC that is
compliant with ISO/IEC 18000-63, ISO/IEC 18000-64
(TOTAL), and EPCTM Class-1 Generation-2. The chip offers
an advanced feature set leading to a performance beyond
that of standard Gen2 chips and can be either battery
powered or beam powered by the RF energy transmitted
from a reader. In a battery assisted passive (BAP)
configuration, the EM4325 offers superior reading range and
reliability compared to purely passive RFID solutions.
ISO 18000-63 (Gen2) & 18000-64 (TOTAL) compliant
EPCTM Gen2 compliant
AIAGTM B-11 compliant
ATA Spec 2000 Low Memory Tag compliant
4096-bit non-volatile memory (EEPROM)
48-bit manufacturer programmed IC Serial Number
352 bits for UII/EPC encoding
3072 bits for User data / 3008 bits for TOTAL data
EM4325 includes 4096 bits of high speed non-volatile
memory (EEPROM) that is organized into 64 pages with 4
words per page. The chip supports either ISO or EPCTM data
structures that are compliant with EPCglobal Tag Data
Standards, Version 1.10, and is delivered with a Unique
Identifier (UID) to ensure full traceability.
128-bit Register File
BlockErase and BlockWrite commands for high speed
memory transactions
BlockPermalock command for User memory
Forward link data rates: 26.7 to 128 kbps assuming
equiprobable data
An integrated temperature sensor is included in the EM4325
and supports the temperature range from -40C to +60C.
The temperature sensor may be used in either purely
passive or BAP applications. Temperature readings can be
made on demand by a reader or the chip may be
programmed to perform self-monitoring with alarm
conditions.
Return link data rates: 40 to 640 kbps with subcarrier
modulated data rates of 0.625 to 320 kbps
TOTAL data rates: 64, 128, 160, 256, or 320 Kbps
Coordinated Universal Time Clock (UTC)
Integrated temperature sensor: -40C to +60C with
typical accuracy of ±1.0C over the full range and
±0.6C over the typical range for cold chain
EM4325 supports advanced applications by providing
programmable external interfaces for an auxiliary function
and a 4-bit I/O port. The auxiliary function may be configured
as an input for tamper detection or as an output for
notification of RF events to external devices. The 4-bit I/O
may be configured to support 4 discrete signals or as a
Serial Peripheral Interface (SPI) bus. The chip may serve as
either an SPI Master device or an SPI Slave device. The
programmable external interfaces allow the EM4325 to
function as an RF front end and protocol handler in
advanced RFID tags or embedded applications. In a
passive configuration, the programmable external interfaces
allow the EM4325 to serve as a SPI Master with energy
harvesting and provide power to external components.
Programmable monitoring and alarm conditions for
temperature sensor including time stamp
Programmable auxiliary function: input for tamper
detection or output for notification of RF events
Programmable 4-bit I/O port: configurable as 4 discrete
signals or as a Serial Peripheral Interface (SPI) Bus
Battery assistance for superior reading range and
reading reliability
Rectifier that allows purely passive operation in case the
battery is flat or not present
Battery supply management to prolong battery life
Battery supply range: 1.25V to 3.6V1)
Low battery alarm threshold: 1.3V or 2.2V
Extended temperature range: -40C to +85C
Battery supply management is provided to prolong battery
life in BAP applications. The chip supports programmable
duty cycle control, auto-switching between battery powered
and beam powered operation, and programmable
enable/disable of an ultra-low power mode for extended
storage applications.
Applications
RFID tags:
Supply chain management, tracking and tracing,
reusable containers and pallets, access control,
asset control, cold chain monitoring, sensor monitoring,
E-seals, Gen2 side-channel for active RFID tags
