K531 is an ISO/IEC 14443 OEM module. It is suitable to read or write Philips MIFARE and DESFIRE leading products, as well any T=CL compliant tag or card from any other manufacturer.
Mounted on our rectangular antenna, K531 becomes a ready-to-use versatile contactless coupler, that can be embedded in virtually any kind of appliance : vending machine, card printer, access control gate, enrollement station, ...
Common features
Contactless interface
- PCD compliant with ISO/IEC 14443 (1, 2, 3 and 4, both A and B types),
- T=CL protocol embedded in coupler's firmware (256-byte frames),
- Supported contactless smartcards (partial list) :
- NXP Mifare Classic & Mifare UltraLight, Desfire, ProX, SmartMX,
- Infineon SLE66, STMicroelectronics ST19, Atmel AT88,
- ST SR176 and SRiX, ASK CTS256B and CTS512B, Inside PicoTag and HID iClass (read only),
- Calypso (option),
- NFC objects or mobile phones in 14443 card emulation mode.
- 13.56MHz RFID transmission, baudrate 106, 212, 424 or 847 kbps,
- NXP/Philips Semiconductors MfRC531 chipset featuring CRYPTO1 cipher unit with secure storage for Mifare keys,
- Card operating distance : 0 to 7.5cm (depending on the card).
Antenna and interface
- Small footprint antenna : 45mm x 69mm x 15mm,
- Ferrite shielding between the antenna and the module,
- 8 pins female connector (JST SHR-08V-S-B), only 4 wires required for normal operation (Vcc + Gnd + RX/TX),
- Power supply : 5V DC, 150mA typical,
- Extended temperature range (-20 to +80 °C).
Product family
K531-TTL
- K531 with antenna,
- Serial communication at TTL level (RX/TX at 0/5V),
- Baudrates : 38400bps (default), 115200bps or 9600bps.
K531-TLL is perfect for in-design integration.
K531-232
- K531 with antenna,
- Serial communication according to RS-232 standard (RX/TX at +12/-12V),
- Baudrates : 38400bps (default), 115200bps or 9600bps.
K531-232 offers same functions as CSB4 when you want to install the reader in your own encasing.
K531-485
- K531 with antenna,
- Serial communication according to RS-485 standard (bus A/B),
- Baudrates : 38400bps (default) or 9600bps.
K531-485 allows long distance operation.
If you're looking for a nice encasing for K531-485, take a look at IWM-K632 reader ; our wall-mount proximity reader can also be flashed with K531-485 firmware.
Development and integration
- Unified SpringProx API, available in the developer's kit (SDK for K531) ; 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,
- Simplified ASCII command set for instant operation from inexpensive host microcontroller.
Custom design
Need custom functions into your K531 ? We can also develop and embed a dedicated firmware into the K531 in order to gain the highest performances or to free the host from any card-related processing.
