3.2

Data-rate Generator

The data rate is binary programmable to operate at any data rate between RF/2 and RF/128 or

equal to any of the fixed e5550/e5551 and T5554 bit rates (RF/8, RF/16, RF/32, RF/40, RF/50,

RF/64, RF/100, and RF/128).

Write Decoder

HV Generator

DC Supply

This function decodes the write gaps and verifies the validity of the data stream according to the

Atmel e555x write method (pulse interval encoding).

This on-chip charge pump circuit generates the high voltage required for programming of the

EEPROM.

Power is externally supplied to the IDIC via the two coil connections. The IC rectifies and regu-

lates this RF source and uses it to generate its supply voltage.

3.8

Power-On Reset (POR)

This circuit delays the IDIC functionality until an acceptable voltage threshold has been reached.

Clock Extraction

The clock extraction circuit uses the external RF signal as its internal clock source.

Controller

The control-logic module executes the following functions:

• Loads mode register with configuration data from EEPROM block 0 after power-on and also

during reading

• Controls memory access (read, write)

• Handles write data transmission and write error modes

The first two bits of the reader to tag data stream are the opcode, for example, write, direct

access, or reset.

In password mode, the 32 bits received after the opcode are compared with the password stored

in memory block 7.

3.9

Mode Register

The mode register stores the configuration data from the EEPROM block 0. It is continually

refreshed at the start of every block read and (re-)loaded after any POR event or reset com-

mand. On delivery, the mode register is preprogrammed with the value 0014 8000h which

corresponds to continuous read of block 0, Manchester coded, RF/64.
