1.1 Description
This document describes the features and operational characteristics of the RI-STU-TRDC-01 & -02
S6350 High Frequency Multi-Protocol Readers. The RI-STU-TRDC-02 reader is shown in Figure 1.
The S6350 Reader operates at a frequency of 13.56MHz and is compatible with both standard and
ISO/IEC 15693 Tag-it inlays and tags. This reference guide provides the details that are necessary to
properly interface and use the reader as a part of an integrated system.
In compliance with the ISO/IEC 15693 standard, a global open standard for optimal use under
different regulatory and noise environments around the world, the S6350 Reader allows for the
interoperability of inlays and tags from multiple manufacturers.
Figure 1: S6350 High Frequency Reader
1.1.1 Programming Interface
The S6350 Reader is designed to operate as a part of a host-based reader system, which essentially
relegates the reader to be a slave to the host. Host-to-Tag-it reader serial communications are
accomplished within data packets whereby communications from the host to the reader are known as
requests, and replies from the reader to the host are known as responses. This communication
occurs at RS-232 levels using 57,000 baud, 8 data bits, 1 start bit, 1 stop bit and no parity. By
definition, the host is always the primary station and initiates all communication sequences. These
sequences consist of request/response pairs where the host waits for a response prior to continuing.

2.1 General Specification
This chapter describes the electrical and mechanical specifications of the S6350 RI-STU-TRDC-02
reader. Operating at a frequency of 13.56 MHz, this low profile, low power device is designed to be
easily integrated into many systems as an embedded device. All reader I/O is accomplished through
the use of a 16-pin header connector (labeled as CN1), to include all communication, which is
asynchronous RS232 as controlled by a host system.
2.1.1 Functional Requirements
The following parameters define the functional requirements and operational environment of the
S6350 reader.
Parameter Specifications
Operating temperature -20oC to +70o C
Storage temperature
(500 hours) -40oC to +85oC
Thermal shock -40oC to +85oC, using MIL-STD-810E, Method 503.3,
for 100 cycles duration, 30 minutes per temperature.
Mechanical shock 5 Gs at 10 ms, half sinusoidal waves, 6 axes (MIL STD-
801E, Method 516.3)
Vibration 15 Hz to 500 Hz, 1 g peak, 30 minutes sweep,
logarithmic (MIL-STD-810E, Method 514.4)
Humidity 500 hours at 80% humidity, non-condensing at 70oC
Operating frequencies 13.56 MHz up-link and down-link
Transponder types 13.56 MHz TI Tag-it™ tag (Standard & ISO tag)
Standard compliance FCC Part 15, Subpart C, “Intentional Radiator”
2.1.2 Power Supply
Input Voltage 5 ± .5 VDC
Average quiescent current 90mA
Average current during read 200mA (for TAG-ITtags)
(Dependent on read rate)
Maximum current during read 250mA
2.1.3 Output Power
Output Power 120mW into 50 Ohms (Typical)
CAUTION:
The S 6350 reader is an intentional radiator, and when
integrated, the integrator is subject to meeting FCC Part
15, Subpart C, and similar tenets under European
Standard EN 300330.

2.1.4 Required Antenna Parameters
Impedance 50Ω±5Ωat 13.56 MHz
Loaded Q 10 < Q < 30
Note:
As no standard antenna is provided by Texas Instruments for the
S6350 reader, the noted required antenna parameters must be
closely followed by the integrator for the reader to operate properly.
2.1.5 Input / output pins (CN1 pins 3 and 4)
Pins 3 and 4 on CN1 may be configured by software commands to read a logic level input or to
switch an external load to ground (no pull-up is provided).
Figure 2: Example Circuit Diagram of an IO pin
When used as a switch to ground the following ratings should not be exceeded:
Maximum voltage 20V
Maximum current 50mA
CAUTION:
Exceeding this Voltage and Current limit could cause
permanent damage to the reader.
Note:
That if an output has been set by a software command the state will
always read back as a logic 0.

2.1.6 Baseband receiver
Minimum data pulse width 5uS
Maximum data pulse width 500uS
Typical settling time 50uS from the first transition
Note:
The receiver extracts the mean level of the incoming data stream as
a reference. This takes approximately 50uS; therefore the data
output of the receiver is not valid until after this time.
2.1.7 Connector Details
All reader input and output is provided through a 16-pin header connector that is mounted on the
backside of the reader for the RI-STU-TRDC-02 and on the component side for the RI-STU-
TRDC-01. The details and orientation of each connector pin are provided in the following tables.

3.1 Serial Protocol Definition
The S6350 reader accepts and sends data at RS232 levels, 57600 baud, 8 data bits, 1 start bit,
1 stop bit and no parity. The data packet from the host to the reader is known as the request
and the reply from the reader to the host as the response. The host is always the primary station
and initiates all communication sequences. These consist of request/response pairs where the
host waits for a response before continuing. The S6350 reader does not use the node address.

3.1.3 Command Flags Request
The command flags in the request packet control the actions of the reader. The meanings of the
bits are defined below.
Bits 0-3 Reserved for future use and should be set to ‘0’ for upward
compatibility.
Bit 4 Is the address flag and if set, the command is only performed on
transponders whose address matches the data section of the packet.
Bits 5-7 Reserved for future use and should be set to ‘0’ for upward
compatibility.

September 2001 S6350 Reader Reference Guide
19
3.1.4 Command Flags Response
The command flags in the response packet report the actions of the reader. The meanings of
the bits are defined below.
Bits 0-3 Reserved for future use.
Bit 4 Error flag. If this flag is set the command was unsuccessful and the
data section of the response packet contains the error code. (See
section Appendix B for a list of error codes.)
Bits 5-7 Reserved for future use.
3.1.5 BCC
A Block Check Character (BCC) is used for error detection and is attached to the end of the
packet. The 16 bit BCC is calculated on all the bytes of the packet including the SOF. The BCC
consists of two parts: the LSbyte is a Longitudinal Redundancy Check (LRC) and the MSbyte is
the ones compliment of the LRC. The LRC is calculated by performing a cumulative Exclusive-
OR operation on all the bytes of the packet.
3.1.6 Example Request Packet
01 hex SOF
0A hex LSbyte of length
00hex MSbyte of length
00hex LSbyte of node address
00hex MSbyte of node address

3.2 Command Definitions
3.2.1 Tag-it™ HF Command Definitions
Command Function (Tag-it HF) Command Code
Read Single Non-addressed & Addressed Block 02hex
Write Single Non-addressed & Addressed Block 03hex
Lock Single Non-addressed & Addressed Block 04hex
Read Transponder Details 05hex
Special Read Block Command 0Fhex
Read Block Command (02hex)
Reads a single block of data from a Tag-itTM transponder. If the address flag is set, the
address forms the first part of the data section (LSbyte first), followed by a single byte
containing the block number to be read. If the address flag is clear the data section
only contains the block number.
Example
Read block 3 of a Tag-itTM transponder whose address is 0134A4D5hex
Request packet
01 0E 00 00 00 10 02 D5 A4 34 01 03 5A A5hex
The response packet is similar to the request packet, with the data section containing
the data received from the transponder (LSbyte first) followed by a single byte
indicating the lock status and then another single byte containing the block address.
The two LSB’s of the lock status byte reflect the two lock bits in the transponder.
Example
Response packet
01 0F 00 00 00 00 02 33 22 11 00 00 03 0F F0hex
00112233hex read from unlocked block 3 of a Tag-itTM transponder.
Write Block Command (03hex)
Writes a single block of data to a Tag-itTM transponder. If the address flag is set, the
address forms the first part of the data section, followed by a single byte containing the
block number to be written. The data to be written follows the block number. If the
address flag is clear the data section only contains the block byte and the data to be
written.
Example
Write Block 4 of a Tag-itTM transponder whose address is 000134A4hex with data
01234567hex
Request packet
01 12 00 00 00 10 03 A4 34 01 00 04 67 45 23 01 95 6Ahex
The response packet is similar to the request packet; with the data section containing
00hex for a successful write operation.
