SIC7888 is read/write low frequency FDX RFID microchip intentionally designed to maximize read range. Air protocol and command is compatible with Hitag-S system. The on-chip 1184-bits EEPROM allow additional information to be stored for custom user applications or on-site database. The chip contains 32-Bit Unique Identification Number for Anti-collision and 64-bits traceability data for optional identification. The chip has 2-Level of password for read authorization and read/write authorization.

The chip can be configured to serve most popular standard in low frequency RFID such as FECAVA, FDX-B and EM format or proprietary system. Communication mode can be set either in tag-talk-first (TTF) mode to use in traditional system or reader-talk-first in application required anti-collision. In term of performance, SIC boosting-up technique, deep modulation (coil damping) and extremely low power consumption design are employed to obtain increasing performance in read range. SIC7888 incorporates tunable resonant capacitor to accommodate variation of inductance in production process to bring resonant frequency of transponder to target. Adjusting tuning capacitor through air command allow 100% maximum and equal read range on production yields.
