型號(hào)： U3280M

類(lèi)別： 集成電路

描述： Description The U3280M is a transponder interface for use in contactless ID systems, remote control systems, tag and sensor applications. It supplies the microcontroller with power from an RF field via an LC-resonant circuit and it enables contactless bi-directional data communication via this RF field. It includes power management that handles switching between the magnetic field and a battery power supply. To store permanent data like an identifier code and configuration data, the U3280M includes a 512-bit EEPROM with a serial interface. Features ? Contactless Power Supply and Communication Interface ? Up to 10 kbaud Data Rate (R/O) ? Power Management for Contactless and Battery Power Supply ? Frequency Range 100 kHz to 150 kHz ? 32 x 16-bit EEPROM ? Two-wire Serial Interface ? Shift Register Supported Bi-phase and Manchester Modulator Stage ? Reset I/O Line ? Field Clock Extractor ? Field and Gap Detection Output for Wake-up and Data Reception ? Field Modulator with Energy-saving Damping Stage Applications ? Main Areas ?? – Access Control ?? – Telemetry ?? – Wireless Sensors ? Examples: ?? – Wireless Passive Access and Active Alarm Control for Protection of Valuables ?? – Contactless Position Sensors for Alignments of Machines ?? – Contactless Status Verification and/or Data Readout from Sensors
