Features

• Dual-Port Nonvolatile Memory - RFID and Serial

• Two-Wire Serial Interface:

– Compatible with AT24C08, and similar products from others

– Supports standard byte and page read/write commands

– Programmable Access Protection to limit reads or writes from either port

– Coil connection detection

• RFID Interface:

– 125 kHz carrier frequency for long range access

– 2-wire connection to external coil antenna and tuning capacitor

– Multi-tag management to handle several tags in the field at once

– 11 RFID commands for tag control and memory read/write

– Ultra low power single bit write - 20µA

• Highly-Reliable EEPROM Memory

– 8K bits (1K bytes)

– Organized as 8 blocks of 128 bytes each

– 16-byte page write, 10ms write time

1K x 8

Dual Access

EEPROM with

RFID and Serial

Interfaces

– Additional memory for access protection and ID number

– 10 years retention, 100K write cycle endurance

– -40° to +85° operation

• Standard 8-lead SOIC package

• 2.4 to 5.5V Supply Voltage

Description

The chip functions as Dual Access EEPROM, with both a wired serial port and a wireless RFID

port used to access the memory. Access permissions are set from the serial inteface side to

isolate blocks of memory from improper access depending on the situation. The RFID interface

is designed to be powered solely from the attached coil, permitting remote reads and writes of

the device.
