ata5577m1330c-ppmy [datasheet] 9333b?rfid?05/14 2 1. description the atmel ? ata5577m1330c-ppmy is a contactless read/ write identification transponder (idic ? ) for applications in the 125khz frequency band. it consists of a plastic brick whic h accommodates the read/write idic ata5577m1330c. the antenna comprises an inductor which in combination of the on-ch ip capacitor serves as power supply and bi-directional communication interface. the on-chip 363-bit eeprom (11 bl ocks with 33 bits each) can be read and writ ten block-wise from a base station (reader). two dedicated blocks are reserved for setting the idic operating modes. another block may be used for a password to prevent unauthorized writing. data is transmitted from the idic (uplink) using load modulat ion. this is achieved by damping the rf field with a resistive load. the ic receives and decodes serial base station commands (downlink) which ar e encoded as 100% amplitude- modulated (ook) pulse-inte rval-encoded bit streams. figure 1-1. rfid system using atmel ata5577m1-ppmy transponder
