HDX RFID Integrated Circuit
INTEGRATED CIRCUITS DIVISION
Description
The NCD1015-LGA is a read/write module to be used in HDX contact-less RFID devices for single transponder
applications in the area of electronic animal identification, operating in the low frequency (134.2 kHz) range, and
supporting ISO 11784/85 standards.
The NCD1015-LGA contains an ASIC and 2 internal capacitors: one, a resonant capacitor, and the other a storage
capacitor. The ASIC contains 4 memory blocks of 33 bits each, based on field programmable, non-volatile EEPROM.
Each block contains 32 data bits (bit 1 ... bit 32). Each of the blocks can be write-protected through an associated lock
bit, which is bit 0 of the corresponding block. Blocks 1 and 2 are referred to as the 64-bit identification data page 1
which is secured by an associated 16-bit CRC. Blocks 0 and 7 contain configuration parameters, as well as the option
to irreversibly lock the RFID device.
The HDX transponder IC receives Write-Block requests from the reader as a pulse interval encoded, 100% amplitude
modulated data signal.
Return data transmission from the transponder to the reader utilizes FSK encoded modulation. This is achieved by a
serial data stream controlled Frequency Shift Keying (FSK) of the transponder's resonant circuit oscillation with an
additional on-chip modulation capacitor between the two transponder terminals HF and GND. The passive
transponder uses the supplied RF signal to obtain the energy needed to send the 64-bit ID code to the reader.

4. Functional Overview and Description
4.1 Power Transfer
Power transfer to the tag is accomplished by radio frequency through coupling antennas in the transponder and the
reader. The reader and 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 with 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 data using Frequency Shift Keying (FSK), utilizing the energy stored in the capacitor CL. The
charge phase is followed directly by the read phase.

4.2 Communication Signal Interface - Tag to Reader
4.2.1 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 a data bit '1' (td1=16/f1) and f0 for the data bit '0' (td0 = 16/f0).
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 3 shows the FSK encoding principle used.
Figure 3: FSK Transmission Used During the Read Phase
4.2.2 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.
4.3 Communication Signal Interface - Reader to Tag
4.3.1 Modulation
Communication between reader and transponder takes place using ASK modulation of the RF field with a modulation
index of ~100%. The carrier frequency of the RF operating field is fC = 134.2 kHz.
4.3.2 Reader Data Rate and Data Coding
The reader to transponder communication uses Pulse Interval Coding (PIC). The reader creates pulses by switching
the carrier on and off as described below. The modulation index of this amplitude modulation is 90% to 100%. The
time between the falling edges of the pulses determines either the value of the data bit, "0" or "1", a Code violation, or
a Stop (EOF) condition. t1 separates the single intervals. Its duration is t1 < 40· tC.

The default PIC threshold is configured for a medium data rate of 2.35 kbit/s, realized for example with a low bit period
of td0 = 350 s and a high bit period of td1 = 500 s. The regenerated clock is available continuously during t1.
4.3.3 Modulation
Communication between reader and transponder takes place using ASK modulation of the RF field with a modulation
index of ~100%. The carrier frequency of the RF operating field is fC = 134.2kHz.
Figure 5: Reader to Tag - Encoding of Start of Frame
The End of Frame (EOF) condition of any reader request is defined as the rising edge of the RF field followed by an
RF field activation time (Teoff) longer than the maximum Td1 value (72 clock cycles).

4.4 Write Phase and the Programming of Data
A new identification number can be programmed into the OTP transponder in the following manner: After the charge
phase, the transponder enters the write mode provided that the reader starts to modulate the field by switching the
transmitter on and off. Writing means that the transponder shifts the received bits into an internal shift register. After
the write phase the reader's transmitter is switched on for the EEPROM programming time in order to energize the
process of programming the shift register's data into the EEPROM. Each 33 data bits of a block, including the lock bit,
are programmed simultaneously into the EEPROM.

5. Transmission Protocol
The transmission protocol defines the mechanism to exchange requests and data between the reader and the
transponder. The reader always starts the transmission, and the transponder does not start transmitting its response
until the reader's RF field is turned off.
The different data exchanges that can happen between reader and transponder are summarized in the lines below:
The requests that can be performed by the transponder built using the NCD1015-IC are as follows:
Charge-Only Read
The content of page 1 is read without any specific page address by just charging (powering-up) the transponder for up
to 50 ms.(ISO 11785 compatibility mode).
Write Block
Following the command and the block address, the lock bit(s) and the 32 data bits to be programmed with the
associated 16 CRC bits are sent to the transponder. The 32 data bits together with the associated lock bit are written
into the specified block simultaneously. Transponder response starts after the RF field is turned off.
Note: Each data block can be locked by setting the associated lock bit in order to create a read-only access and to
disable further re-programming of this block.
Note: After writing block 1 and block 2, it is recommended to send a Charge Only Read command to verify successful
writing.
5.1 Data Format Definitions
5.1.1 Reader Command - Request Format
A Charge-Read Only request is generated by just charging the transponder: The demodulator must start working
once the reader stops generating the electromagnetic field. It counts the number of cycles while the electromagnetic
field is low, if that number t1 is larger than 40· tC, the tag will respond to a Charge-Read Only request.
If the t1 duration is not larger than 40· tC, the system has to wait for a Reader Request Frame (RRF).
The Reader Request Frame Format as sent by the reader is shown in Figure 8.

5.2 CRC-CCITT ERROR CHECKING
The CRC error checking circuitry generates a 16-bit 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.

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)
6. Memory
6.1 Memory Block
The memory is structured into 8 Blocks of 32 bits each. In addition a Lock Bit is provided as Bit 0 corresponding to
each Block. Two Blocks form one Page, of which 2 exist. The following table shows the memory organization.

6.1.1 Page 1 - Identification Data
Page 1 is used for the Identification Data as specified in ISO/ IEC 11784. This page is locked if the Lock Bits of the
corresponding Blocks are set to "1". If the Page is locked, the stored value can not be overwritten.
6.1.2 Page 4 - Configuration Register + Management Register
Page 4 consists of Block 0, which is the Management Register, as the Most Significant Bits and the Block 7, which is
the Configuration Register as the Least Significant Bits of it. This Page is locked if the Lock Bits of the corresponding
Blocks are set to "1". If the Page is locked, the stored value can not be overwritten.
