The V640 series is a 134 kHz electromagnetic inductive RFID system developed for carrier ID reading/writing (CIDRW) in semiconductor applications. It conforms to the ISO/IEC 18000-2 wireless interface standard and to SEMI E4, E5, E99, E15.1 and E144-0312; the antenna dimensions conform to SEMI E15.1. It reads and writes Texas Instruments glass transponders, including multi-page types. The system consists of a CIDRW head (V640-HS61 standard, V640-HS62 long-range), a CIDRW amplifier unit and, where needed, the V700-L22-V2 CIDRW controller for the SECS I/II protocol.
The amplifier unit comes in RS-232C/RS-485 (V640-HAM11-V5, -L-V5) and Ethernet TCP/IP (V640-HAM11-ETN-V5, -L-ETN-V5) versions; the Ethernet types offer an embedded web browser for configuration and read/write tests. Test mode, CIDRW head status detection and noise measurement functions are provided. With the V700-L11 ID Link Unit, up to 31 units can be connected over RS-485 up to 50 m, and a faulty amplifier can be replaced while the system remains on. The units operate at 0 to 40 °C with IP20 protection; the amplifier measures 80 × 185 × 43 mm.
