Ideal for applications in
building access control systems, industrial automation, consumer and industrial
segments, and as tokens, key fobs or transponders, this new device offers
designers the ability to develop more flexible, high-performance tag devices.
The Atmel ATA5577M1330C-PP enhances the Atmel LF RFID portfolio with a
stand-alone, fully functional tag that includes an antenna coil trimmed to an
operating frequency of 125kHz.
The new device provides the highest flexibility for universal use, which is a
key market requirement. The new Atmel RFID device provides 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 Frontend Register (AFE) enables the chip's
analog front end circuitry to adapt to the transponder and reader system for
maximum performance. The ATA5577M1330C-PP is the only device on the market where
the 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
The new 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.
Availability and Pricing
Samples of the Atmel ATA5577M1330C-PP in 12mm x 5.9mm x 3mm brick packages are
available now. Pricing starts at US$1.93 for bulk shipments of 4,000-piece
quantities. To support engineers and to simplify the design of complete RFID
systems, Atmel provides evaluation kits (ATA2270-EK1, ATA5505-EK1) with the
sample transponders. These kits are based on Atmel's well-known AVR®
microcontrollers and provide Windows® PC software, C source code for programming
the AVR device, and PCB Gerber data for the reader board.
