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
