HT6720

Code Package

A total of 96 bits information can be stored in the

HT6720, from which 64 bits are customer programma-

ble.

Agent ID: This 8-bit wide code is not customer program-

mable and is supplied together with the data writer after

registering to Holtek. The writer generates the code au-

tomatically.

Customer ID: This area is for the Agent, for example

used to store current number of customer.

Category ID: Can be used to store the application field

information code.

Product ID: Storing the contents of the user ID number

or data.

Data CRC: A 16 bits of CRC code is generated automat-

ically by the writer.

Note:

The value of the antenna inductance is 11mH, however the optimum value will be changed slightly due to the

variation of the internal resonance capacitor (10pF typically) during process.
