Multi-protocol RFID IC:
–
–
Operation:Read/Write
Number of bytes:
–
–
Tag scan rate:Variable by host
Carrier frequency:External 13.56 MHz crystal controlled
Carrier field drive level:
–
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 µA (1 µA typical)
Protocol Control: Atmel pre-programmed RISC Microprocessor
Software program memory: Pre-programmed with Innovision Firmware revision
V2.7
Data memory: Reserved
Non-volatile memory: Reserved
Interfaces:

ISO/IEC14443A parts 2 & 3 (frame format)
User transparent operation with both the Philips Mifare Ultralight and
Innovision R&T low-cost Jewel tags
Ultralight: 48 user Read/Write bytes
Jewel: 96 user Read/Write bytes
Four software adjustable carrier field drive and Q levels determined by
selection of output stage drive impedance:
3 wire SPI interface at 115 kBaud
Level1 – 40 Ω
Level2 – 20 Ω (Default for v2.7)
Level3 – 10 Ω
Level4 – 5 Ω
