RFID, RF Access, Monitoring ICs: AS3953B-BSWF

AS3953B-BSWF is an integrated circuit (IC) that belongs to the family of radio frequency identification (RFID) and radio frequency access (RFA) monitoring ICs. The IC is manufactured by Atmel Corporation of San Jose, California, and is based on the Atmel AVR 8-bit microcontroller core with high performance RF transceiver. It is particularly suited for micro transponder applications in the industrial, automotive, consumer and medical markets.

The AS3953B-BSWF combines a high performance RFA transceiver and a low power, 16 kB AVR microcontroller core. The IC contains all the necessary components for a micro transponder application. The AVR core is optimized for low power applications and can support clock speeds up to 32MHz. It has 512 bytes of SRAM, 512 bytes of EEPROM, a 20 bit address bus and 32 general purpose input/output lines.

The RF transceiver is based on a 2.4GHz FSK transceiver which supports a variety of fundamental protocol layers including 802.15.4-2003/2006, ISO/IEC 18000-3 and ECMA. It is an integrated transceiver which supports up to 200MHz of programmable frequency range, 32 reception channels and supports up to 30mA of RF peak current draw.

The AS3953B-BSWF is designed for applications where low-cost, low power RFID tags are required. It has a wide range of features which include small tag size, low power operation, wireless communications, improved selectivity and sensitivity, reduced power consumption, and flexible memory options. The IC also supports a range of application protocols including NXP, Sony, and Atmel\'s own proprietary EFID protocol.

In terms of physical layout, the AS3953B-BSWF is a 21 pin, 0.35 square inch package with an on-board integrated antenna. The antenna has a 50Ω impedance, and provides excellent communication at short ranges. The IC is powered by an external 3V battery, and is known to dissipate less than 4mA at 3V while receiving and transmitting signals.

The AS3953B-BSWF is capable of encoding, storing, and communicating information wirelessly, making it an ideal choice for micro transponder applications. It is suitable for applications such as access control, item tracking, asset monitoring, and product authentication. It provides excellent security and data integrity, and is also highly reliable.

In summary, the AS3953B-BSWF is a highly powerful and reliable IC that provides assistance in a wide range of RFID and RFA applications. It has a low power consumption, a wide range of features, and is capable of encoding, storing, and communicating data wirelessly. It is particularly suitable for micro transponder applications in the industrial, automotive, consumer and medical markets.
