Description



Description

The EM4298 is a single chip decoder which enables fast and cost-effective RFID UHF reader designs. EM4298 can be used in mixed populations of RW and RO RFID tags.
Data encoding and decoding options are configurable by an external uC. PIE or PPE encoding can be used for the forward link. The return data link can be in FM0, PPE or Miller coding with data bitrate is variable up to 640 kbit/s. The EM4298 is able to track up to ±10% in tag clock frequency variation.
The EM4298 is expected to work as a memory mapped peripheral. The chip verifies the received data against CRC but the CRC is also passed to the uC. The configuration can be changed by the uC at any time, but might result in the loss of one word. The EM4298 chip can be reset by the uC when necessary e.g. when synchronization is lost. In this case the chip configuration is kept.
One word of up to 552 bits is buffered.
The chip implements status and statistic words which contain information like overflow, error, channel, edge counter, CRC error counter, etc.
