1 General description
SLRC610, the low-cost RFID frontend.
The SLRC610 multi-protocol NFC frontend IC supports the following operating modes:
• Read/write mode supporting ISO/IEC 15693
• Read/write mode supporting ICODE EPC UID/ EPC OTP
• Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
The SLRC610 supports the vicinity protocol according to ISO/IEC15693, EPC UID and ISO/IEC 18000-3 mode
3/ EPC Class-1 HF.
The following host interfaces are supported:
• Serial Peripheral Interface (SPI)
• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)
• I2C-bus interface (two versions are implemented: I2C and I2CL)
The SLRC610 supports the connection of a secure access module (SAM). A dedicated separate I2C interface is implemented for a connection of the SAM. The SAM can be used for high secure key storage and acts as a very performant crypto coprocessor. A dedicated SAM is available for connection to the SLRC610.
2 Features and benefits
• RFID frontend
• Supports ISO/IEC15693, ICODE EPC UID and ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
• Low-power card detection
• Antenna connection with minimum number of external components
• Supported host interfaces:
– SPI up to 10 Mbit/s
– I2C-bus interfaces up to 400 kBd in Fast mode, up to 1000 kBd in Fast mode plus
– RS232 Serial UART up to 1228.8 kBd, with voltage levels dependent on pin voltage supply
• Separate I2C-bus interface for connection of a secure access module (SAM)
• FIFO buffer with size of 512 byte for highest transaction performance
• Flexible and efficient power saving modes including hard power down, standby and low-power card detection
• Cost saving by integrated PLL to derive system clock from 27.12 MHz RF quartz crystal
• 3 V to 5.5 V power supply (SLRC61002)
2.5 V to 5.5 V power supply (SLRC61003)
• Up to 8 free programmable input/output pins
• The version SLRC61003 offers a more flexible configuration for Low-Power Card detection compared to the SLRC6102 with the new register LPCD_OPTIONS. In addition, the SLRC61003 offers new additional settings for the Load Protocol which fit very well to smaller antennas. The SLRC61003 is therefore the recommended version for new designs
