FUNCTIONAL DESCRIPTION
Memory organization
The memory of the transponder consists of 256 bits
EEPROM memory and is organized in 8 pages with 32 bits
each.
Depending on the operating mode the EEPROM is
organized as described in Table 1.

Operating modes
With the configuration byte, the operating mode and the
access rights to the memory can be selected.
During power-up of the transponder the configuration byte
is read from the EEPROM of the transponder.
The HT2DC20S20 can operate in several modes:
Crypto mode
Mode for writing or reading the transponder with
encrypted data transmission.
Password mode
Mode for writing or reading the transponder with plain
data transmission.
Public mode A (Manchester)
Read-only mode. The 64 bits of the user pages 4 and 5
are cyclically transmitted to the read and write device.
Public mode B (biphase)
Read-only mode according to ISO standards 11784
and 11785 for animal identification. The 128 bits of the
user pages 4 to 7 are cyclically transmitted to the read
and write device.
Public mode C (biphase)
Read-only mode emulating the read operation of the
PCF793X (with a slightly different program mode
check). In the public mode C the 128 bits of the user
pages 4 to 7 are cyclically transmitted to the read and
write device.
