NCD1015-50RO
HDX Robust 50mm Transponder
INTEGRATED CIRCUITS DIVISION
Description
NCD1015-50RO is a contact-less Read-Only RFID
device for single transponder applications in the area
of electronic identification operating in the low
frequency (134.2 kHz) range, and supporting ISO
11784/85 standards.
The passive transponder uses the supplied RF signal
to obtain the energy needed to send the 64-bit ID code
to the reader. Return data transmission from the
transponder to the reader utilizes FSK encoded
modulation.
The NCD1015-50RO contains a 64-bit identification
data page 1 which is secured by an associated 16 bit
CRC.

2. Functional Overview and Description
2.1 Power Transfer
Power transfer to the tag is accomplished by magnetic
coupling of the transponder and reader antenna. The
reader and the transponder operate in a sequential
mode with time-separated power and data
transmission cycles. The RF operating field supplies
power at the beginning of the request from the reader
to the HDX transponder. During the charge (or
powering phase) of between 15 and typically 50 ms
the reader generates an electromagnetic field using a
frequency of 134.2 kHz. The resonant circuit of the
transponder is energized, and the induced voltage is
rectified by the integrated circuit to charge the
capacitor CL. The transponder detects the end of the
charge burst (EOB) and transmits its data using
Frequency Shift Keying (FSK), utilizing the energy
stored in the capacitor CL. The charge phase is
followed directly by the read phase.
Figure 1: Charge and Read Phase - Voltage at the
Reader’s Exciter and Transponder Coil
2.2 Communication Signal Interface - Tag to
Reader
2.2.1 Frequency
The tag shall be capable of communicating with the
reader via an inductive coupling, whereby the power is
switched off and the data are FSK modulated using
the frequencies:
• f0 = 134.2kHz for the Data “Low Bit” Encoding
(ISO 11785 tolerance)
• f1 = 124.2kHz for the Data “High Bit” Encoding
(ISO 11785 tolerance)
f1 represents the frequency for data bit '1' (td1=16/f1)
and f0 for the data bit '0' (td0 = 16/fc).
The low and high bits have different duration, because
each bit takes 16 RF cycles to transmit. The high bit
has a typical duration of ~130s, the low bit of ~120s.
Figure 2 shows the FSK encoding principle used.
Figure 2: FSK Transmission Used During the
Read Phase
2.2.2 Transponder Data Rate and Data Coding
The data coding is based on the NRZ method thus
achieving an average data rate of ~8kbit/s based on
an equal distribution of '0' and '1' data bits.

2.3.2 CRC - CCITT Error Checking
The CRC error checking circuitry generates a 16 bits
CRC to ensure the integrity of transmitted and
received data packets. The reader and transponder
use the CRC-CCITT (Consultative Committee for
International Telegraph and Telephone) for error
detection.
The 16-bit Write Frame BCC is generated by the
transponder on reception of the complete write data
stream to validate the correct data transmission.

The 16-bit cyclic redundancy code is calculated using
the following polynomial with an initial value of
0000hex:
P(X) = x16 + x12 + x5 + x0
The implemented version of the CRC check has the
following characteristics:
• Reverse CRC-CCITT 16 as described in
ISO/IEC 13239 and used in ISO/IEC
11784/11785.

PRELIMINARY
• The CRC 16-bit shift register is initialized to all
zeros at the beginning of a request.
• The incoming data bits are XOR-ed with the
MSB of the CRC register and is shifted into the
register's LSB.
• After all data bits have been processed, the
CRC register contains the CRC-16 code.
• Reversibility - The original data, together with
associated CRC, when fed back into the same
CRC generator will regenerate the initial value
(all zero's).
