cy8c0104 and cy8c0105 preliminary data sheet july 23, 2004 rev. ** 2 byte tracking the decoding algorithm supports programmable byte tracking. a read can start after the tracking byte(s) has been detected. this feature can be used with read-only transponders (most t5530 transponders start with a 0xe6 header). it can also be used for security because another reader may not read correct data from a transponder if it does not know which tracking system is being used. flash programmability the rfid chip and chipmodule are programmable with smrfid ( sonmicro rfid) software through the uart pins. a user can program assembly code to the available flash memory providing access to control apis and hardware. this eliminates the need for an external microcontroller. because of the programmability of flash in the rfid chip and chipmodule, new features and modifications are easily implemented in user-specific applications. additional features parameters such as rfid tag programming period, internal amplifier gain, and carrier frequency are programmable through the uart and smrfid software. this allows the user to adjust the carrier frequency and baud rate for specific applications. calibration of the rfid chip and chipmodule is performed through the uart interface. general purpose input output (gpio) pins are available to expand the functionality of the devices and to control custom design elements. development tools evaluation kit the rfid evaluation kit (cy3220smrfid-rd) is a complete short-range 125 khz rfid reader. the rfid evaluation kit includes a chipmodule (cy8c0105) equipped with an rs232 serial communication chip to perform all rfid functions including reading and writing to tags, calibration, and communication to a user interface (pc). smrfid (sonmicro rfid) software the smrfid software included in the rfid evaluation kit is a microsoft windows-based interface for testing, programming, and calibrating a chipmodule with the evaluation board. complete software instructions and programming steps are described in the getting started guide and programming guide on the evaluation kit cd. rfid evaluation kit (cy3220smrfid-rd)
