Low-frequency RFID IC has megapads for direct coil bonding.
Press Release Summary:
Featuring gold-bumped pads for direct bonding of copper antenna coil, 363-bit read/write transponder IDIC® ATA5577M2 provides unique ID that guarantees access to secured areas and enables product traceability. It operates according to ISO 11784 and ISO 11785 (FDX-B) standards and, including optional trimmed 250 or 330 pF on-chip capacitors, measures 1 mm wide. With integrated LC-tank-capacitors trimmed to ±3% tolerance, antenna coil is only external component needed.
Original Press Release:
Atmel Launches Low-frequency RF IDIC with Megapads for Direct Coil Bonding
Cartes, Paris, France, November 4, 2008...Atmel® Corporation (Nasdaq: ATML), announced today the availability of the 363-bit read/write transponder IDIC® ATA5577M2. This device features large gold-bumped pads for direct bonding of the copper antenna coil. With integrated LC-tank-capacitors trimmed to a +/- 3% tolerance, the antenna coil is the only external component needed for a complete trimmed tag system, thus providing significant cost savings.
The IDIC provides a manufacturer-programmed unique ID which is vital to guaranteeing access to secured areas. The unique ID also enables the traceability of the product, thus preventing easy cloning or counterfeiting of the tag IC. The unique ID and extended read/write distance have been optimized for next-generation access control applications including hotel rooms, engineering departments, offices, time recording systems, parking lots and customer loyalty and membership cards. In addition, the new device operates according to ISO 11784 and ISO 11785 (FDX-B) standards, making it well-suited for animal identification and waste management applications.
Since the ATA5577 is a low frequency (LF) device, it can be used worldwide. It is not sensitive to rugged environments and can also be used under conditions that normally complicate the application of RFID devices such as water, metal, or dirt; out-of-sight; or being worn on the body.
Including the optional trimmed 250- or 330-pF on-chip capacitors, the ATA5577M2 is only 1 millimeter in width, which allows the chip to be used in almost any transponder package including glass transponders for animal identification.
The device's new architecture enables outstanding read/write performance with differing types of coils, readers, and parameters which is especially important for animal and waste management applications. A special register maximizes the overall read and write distance for each application environment. Thanks to a dedicated write procedure (downlink, reader-to-tag), the write distance has been increased to industry leading distances. This increased write distance is especially beneficial for applications in difficult environments.
Availability and Pricing
Samples are available now as sawn wafer on foil or die in waffle pack. Pricing for the ATA5577M2 as sawn-wafer shipment with quantities of 15k pieces starts at US$ 0.49. To support the system designer, Atmel provides the evaluation kit ATA2270-EK1. This is based on Atmel's LF-RFID reader chip U2270B and the AVR® microcontroller ATmega128. The kit includes all C-routines and PCB layout data in Gerber format. In addition, several tag samples are supplied with the kit for easy system implementation. In addition, a PC-based graphical user interface is also available. The ATA5577M2 can replace and is backward compatible with Atmel's well-known existing LF devices in several applications.
