Atmel e5551 Building Blocks

4.2.1 Analog Front End (AFE)

The AFE includes all circuits which are directly connected to the coil. It generates the IC’s power supply and handles the

bidirectional data communication with the reader unit. It consists of the following blocks:

●

Rectifier to generate a dc supply voltage from the ac coil voltage

Clock extractor

Switchable load between Coil1/ Coil2 for data transmission from the IC to the reader unit (read)

Field gap detector for data transmission from the reader unit into the IC (write)

4.2.2 Controller

The main controller has following functions:

●

Load mode register with configuration data from EEPROM block 0 after power-on and also during reading

Control memory access (read, write)

Handle write data transmission and the write error modes

The first two bits of the write data stream are the OPcode. There are two valid OP-codes (standard and stop) which

are decoded by the controller.

●

In password mode, the 32 bits received after the OPcode are compared with the stored password in block 7.

4.2.3 Bitrate Generator

The bitrate generator can deliver the following bitrates: RF/8 - RF/16 - RF/32 - RF/40 - RF/50 - RF/64 - RF/100 - RF/128

4.2.4 Write Decoder

Decode the detected gaps during writing. Check if write data stream is valid.

4.2.5 Test Logic

Test circuitry allows rapid programming and verification of the IC during test.

4.2.6 HV Generator

Voltage pump which generates ≈ 18V for programming of the EEPROM.
