SA7120A: 128 Bit Read-only Biphase Coded Transponder

for ISO 11784 / 11785 FDX-B (Full Duplex) Application

FEATURES

EEPROM flexibility of data configuration

On-chip resonance capacitor

128 bits of OTP data factory programmed and locked § No external charge storage capacitor required

Customer specific configuration of stored data

Data output in Biphase mode

On-chip full wave rectifier

On-chip data modulator

Biphase data readout conforming to ISO 11784 / 11785 § On-chip high voltage protection / regulation

FDX-B full duplex

On-chip RF frequency clock extractor / prescaler

Carrier frequency 100 to 300 kHz

Low power dissipation

DESCRIPTION

Data is read at the RF interface by means of the on-chip

modulator. The stored bits are clocked out sequentially

during the read operation. An internal power-on reset is

provided which allows the device to start reading out data at

low voltages for improved tag range.

This device is manufactured in the SAMES 1.2µm N-well

EEPROM process. It has 128 bits, factory pre-programmed

and locked in EEPROM memory. Read data is Biphase

coded.

The device has an on-chip rectification circuit that converts

APPLICATIONS

the incoming rf signal to DC power feeding V . There is

also an on-chip data modulator which works in conjunction

with the rectifier. The time base is extracted by an on-chip

RF clock extractor. High voltage protection across the coil

inputs is provided internally. The energy is stored on

capacitance on chip due to low internal power consumption.

The device has an on-chip resonance capacitor connected

between the COIL1 and COIL2 pads. These features result

in a single external component count, comprised of, only the

coil.
