2 atmel ata5577m133 0c-pp [datasheet] 9225b?rfid?04/12 1. description the atmel ? ATA5577M1330C-PP is a contactless r ead/write identificatio n transponder (idic ? ) for applications in the 125khz frequency band. it consists of a plastic brick which acco mmodates the read/write idic ata5577m1330c. the antenna comprises an lc circuit which serves as power supply and bi-directional communication interface. the on-chip 363-bit eeprom (11 blocks with 33 bits each) can be read and written bl ock-wise from a base station (reader). two dedicated blocks are reserved for setting the idic operatin g modes. another block may be used for a password to prevent unauthorized writing. data is transmitted from the idic (uplink) using load modulation. this is achieved by damping the rf field with a resistive loa d. the ic receives and decodes serial base station commands (downlink) which are encoded as 100% amplitude-modulated (ook) pulse-interval-encoded bit streams. figure 1-1. rfid system using atmel ata5577m1-pp transponder data reader or base station power transponder ata5577-pp (ata5577 + coil in plastic brick) ata5577 coil www.datasheet.net/ datasheet pdf - http://www..co.kr/
3 atmel ata5577m133 0c-pp [datasheet] 9225b?rfid?04/12 2. general the transponder consists of a plastic brick which accommodates the following components: atmel ? ata5577m1330c read/write idic ? coil with ferrite core note: the antenna is implemented as a tuned lc circuit 2.1 transponder antenna the antenna consists of a coil and an on-c hip capacitor of atmel ata5577m1330c for tuning the circuit to the nominal carrier frequency of 125khz. the coil has a ferrite core for improv ing the distance of read, writ e and programming operations. 2.2 atmel ata5577m1-pp transponder operation the atmel read/write idic ata5577m1330c is part of the atmel transponder ata557 7m1330c-pp. the data is transmitted bi- directionally between the base station and th e transponder. the transponder receives power via a single coil from the rf signal generated by the base stat ion. the single coil is connected to the chip and al so serves as the ic?s bi-directional communicatio n interface. data is transmitted by modulating the amplitude of the rf si gnal. the register contents are read by damping the coil voltage using an internal load. writing into registers occurs by interr upting the rf field in a specific way. the atmel ata5577m1330c- pp transponder operates at a nominal fr equency of 125khz. there are varying bit rates and encoding schemes. the on-chip 363-bit eeprom (11 blocks with 33 bits each) can be read and writ ten block-wise from a base station (reader). the blocks can be protected against overwriting by using lock bits. two blocks contain atmel?s production information and form a unique id numbering system. another block may contain a password to prev ent unauthorized writ ing. two blocks are reserved for setting the ic's operating modes. see the atme l ata5577c datasheet for more detailed information about atmel ata5577m1330c operating modes. www.datasheet.net/ datasheet pdf - http://www..co.kr/
