Atmel intros low-frequency RFID transponder

Atmel has announced production availability of a low-frequency (LF) RFID transponder device, the Atmel ATA5577M1330C-PP, EE Herald reports.

The device is suitable for applications in building access control systems, industrial automation, consumer and industrial segments, and as tokens, key fobs or transponders.

The RFID device enables with a standalone, 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, PR Newswire writes.

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 analogue 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 analogue behaviour 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 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 moulding 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.
