4407A–SCR–04/05
Reader to reader inductive Near Field Communications capability using Innovision R&T
proprietary protocols in software
Transparent modes for direct software controlled modulation protocols for maximum
flexibility
General Specifications
Multi-protocol RFID IC:
ISO/IEC14443A parts 2 & 3 (frame format)
User transparent operation with both the Philips Mifare Ultralight and
Innovision R&T low-cost Jewel tags
Operation:Read/Write
Number of bytes:
Ultralight: 48 user Read/Write bytes
Jewel: 96 user Read/Write bytes
Tag scan rate:Variable by host
Carrier frequency:External 13.56 MHz crystal controlled
Carrier field drive level:
Four software adjustable carrier field drive and Q levels determined by
selection of output stage drive impedance:
Level1 – 40
Level2 – 20
(Default for v2.7)
Level3 – 10
Level4 – 5
Antenna configuration:Balanced “push-pull” output stages driving a symmetrical
series resonant antenna coil for optimal carrier field generation when operating from
low voltage supply
FCC/ETSI EMC Compliancy:Simple LC low-pass filters used on output stages to
achieve harmonic reduction required for EMC compliancy
Operating voltage range: 2.7 – 3.0 V
Maximum voltage rating: 3.3 V
Peak supply current: < 65 mA peak (depending on drive level selection, antenna
matching and tuning)
Sleep-mode quiescent current: <10
