K531 features
Contactless interface
- Base station (PCD) compliant with ISO/IEC 14443 standard (1, 2, 3 and 4, both type A and type B),
- T=CL protocol embedded in coupler's firmware (256-byte frames),
- Supported contactless smartcards (PICC) (partial list) :
- NXP MIFARE Classic et MIFARE Plus, MIFARE UltraLight, DESfire, ProX, SmartMX,
- Infineon SLE66, STMicroelectronics ST19, Atmel AT88,
- S.T. Microelectronics SR176 et SRiX, ASK CTS256B et CTS512B,
- Inside Contactless PicoTag et HID iClass (numéro de série seulement),
- Calypso (incl. Innovatron radio protocol « 14443-B' »)
(some usages of Calypso cards are patented and subject to a license fee - contact us), - Tags specified by NFC Forum : Type 1 (Innovision Jewel or Topaz), Type 2 and Type 4,
- NFC objects or mobile phones in 14443 card emulation mode (standards ISO/IEC 18092 and 23917).
- RFID transmission : 13.56MHz carrier, baudrate 106, 212, 424 or 847 kbps (PCD mode),
- NXP/Philips Semiconductors RC531 chipset, with CRYPTO1 stream cipher unit and secure storage of MIFARE keys,
- Card operating distance : up to 10cm, depeding on antenna's size and geometry (and depending on the card).
Hardware
- Small footprint module : 26mm x 31mm x 9mm, 20 pins,
- 2 software-controlled LED outputs (CMOS/TTL),
- 1 software-controlled bi-directionnal user pin (CMOS/TTL),
- RX/TX pins (CMOS/TTL) for serial communication (38400bps or 115200bps),
- Both MFIN and MFOUT pins available on the module pinouts for advanced RC531 operation,
- Power supply : 5V DC, max 200mA, 90mA typical (may vary with the antenna),
- Extended temperature range (-20 to +80 °C).
Development and integration
- Unified SpringProx API, available in the developer's kit (SDK for K531 and K632) ; the SDK includes ANSI C source code, to be ported on virtually any target, and Windows binaries,
- Same platform as CSB4, thus allowing fast and easy prototyping on a desktop computer,
- Lightweight ASCII protocol and simple command set for instant operation from inexpensive host microcontroller.
Custom design
Need custom functions into your K531 or K632? We can also develop and embed a dedicated firmware into your module in order to gain the highest performance or to free the host from any card-related processing.
See also RDR-K632, a standalone/reader-only version of K632.
