DESCRIPTION

The MCRF450 is a contactless read/write passive

RFID device that is optimized for 13.56 MHz RF carrier

signal. The device needs an external LC resonant cir-

cuit to communicate with interrogator wirelessly. The

device is powered remotely by rectifying an RF signal

that is transmitted from the interrogator, and transmits

or updates its contents of memory based on com-

mands from the interrogator.

• Three pads for external antenna circuit

• Factory programmed unique 32-bit tag ID

• Interrogator talks first (ITF) or tag talks first (TTF)

operation

• Fast and normal modes for data transmission

• Anti-tearing feature

• Full 32-bit EAS support

• Very low power CMOS design

The device is engineered to be used effectively for item

level tagging applications such as retail and inventory

management, where a large volume of tags are read

and written in the same interrogator field.

• Die, wafer, COB module, PDIP, or SOIC package

options

The device contains 32 blocks of EEPROM memory.

Each block consists of 32 bits. The first three blocks (B0

- B2: 96 bits) are allocated for device operation, the

next 27 blocks (B3 - B29: 864 bits) are for user data,

and the remaining 2 blocks (B30 - B31: 64 bits) are

reserved for future use. The 864 (B3 - B29) user bits

are contactlessly read or written block-wise by interro-

gator commands. All blocks except bits 30 and 31 in

block 0 are write protectable.

The device has two operational modes depending on

the conditions of talk first (TF) and fast read (FR) bits.

These modes are: “tag talks first” (TTF) and “interroga-

tor talks first” (ITF) modes. The device operates in TTF

mode if both TF and FR bits are set. In this mode, the

device transmits its fast read response data (96 bits in

default) as soon as it is energized, and waits for the

next commands. The device operates in the “interroga-

tor talks first” mode, if the TF bit is cleared. In this

mode, the device requires an interrogator command

before it sends any data.
