The device is a stand-alone, fully functional tag that includes an antenna coil trimmed to an operating frequency of 125kHz. It provides the highest flexibility for universal use, supporting a broad range of data rates from RF/2 to RF/128 (64kBit/s to 1kBit/s at 125kHz), modulation and a variety of coding schemes including ASK, FSK, PSK, Manchester, Bi-phase and NRZ. The Atmel-patented digital analog front end register (AFE) enables the chip's analog front end circuitry to adapt to the transponder and reader system for maximum performance. The chips' analog behavior can be tuned in a closed and sealed transponder for increased performance. By eliminating the need to open the transponder for tuning, the on-chip AFE register helps simplify the design and production process significantly. The transponder is available in a standard lead-free zero-pin brick package, which is also used by other Atmel IDIC family members. The package molding makes the transponder very robust so that it can be used in rugged environments that are challenging for competing RFID devices, including underwater, on metal or in dirt.
The on-chip memory contains an Atmel-pre-programmed unique ID (UID) in two additional memory blocks. These locked blocks guarantee a unique, worldwide traceable Atmel number consisting of the Atmel lot number, wafer lot and sequential die number. This makes the device well suited for use in applications that only require a low, basic level of security, while at the same time ensuring compatibility with all kinds of existing RFID systems. The ISO11784/ ISO11785 code structure, along with the de-facto-standard-unique format, can be configured according to the requirements of specific 125kHz applications. The transponder comes in a 12x5.9x3mm brick package.
