RFID Functional Overview

Built on a PSoC (Programmable System-on-Chip)

platform, the RFID Chip and ChipModule eliminate the

need for external components such as filters, amplifiers

and microcontrollers. Approximately 4k of Flash is

available for customization to allow designers to

personalize operations.

The RFID chip and ChipModule generate a 100-150 kHz

RFID field, decode the transponder return signal, and

store data to be processed or sent. The RFID chip and

ChipModule are pre-programmed. In cases where users

desire a custom decoding algorithm or to decode the

signal with other modulations (e.g., bi-phase), the un-

decoded signals are available on pins of the RFID chip.

Byte Tracking

Development Tools

The decoding algorithm supports programmable byte

tracking. A read can start after the tracking byte(s) has

been detected. This feature can be used with read-only

transponders (most T5530 transponders start with a

0xE6 header). It can also be used for security because

another reader may not read correct data from a

transponder if it does not know which tracking system is

being used.

Evaluation Kit

The RFID Evaluation Kit (CY3220SMRFID-RD) is a

complete short-range 125 kHz RFID reader. The RFID

Evaluation Kit includes a ChipModule (CY8C0105)

equipped with an RS232 serial communication chip to

perform all RFID functions including reading and writing

to tags, calibration, and communication to a user

interface (PC).

Flash Programmability

The RFID Chip and ChipModule are programmable with

SMRFID (SonMicro RFID) software through the UART

pins. A user can program assembly code to the available

Flash memory providing access to control APIs and

hardware. This eliminates the need for an external

microcontroller. Because of the programmability of Flash

in the RFID Chip and ChipModule, new features and

modifications are easily implemented in user-specific

applications.

SMRFID (SonMicro RFID) Software

The SMRFID Software included in the RFID Evaluation

Kit is a Microsoft Windows-based interface for testing,

programming, and calibrating a ChipModule with the

Evaluation Board. Complete software instructions and

programming steps are described in the Getting Started

Guide and Programming Guide on the Evaluation Kit

CD.

Additional Features

ꢂ

Parameters such as RFID tag programming

period, internal amplifier gain, and carrier

frequency are programmable through the UART

and SMRFID software. This allows the user to

adjust the carrier frequency and baud rate for

specific applications.

ꢂ

Calibration of the RFID Chip and ChipModule is

performed through the UART interface.

General Purpose Input Output (GPIO) pins are

available to expand the functionality of the

devices and to control custom design elements.

2. Communication Protocol

2.1 UART

This chapter describes the UART communication protocol for communication between the CY8C0104/05 and an interface. Other

communication methods can be implemented upon customer request. Please visit www.sonmicro.com for support in adding a

different communication protocol.

The RFID ChipModule communicates with peripheral devices via 8-byte data packets at 19200 bps. This baud rate can be

increased or decreased through firmware modification. Most commands consist of 8-byte packets but there are also 16-byte data

packets.

The RFID ChipModule sends the received data back to an external device upon receipt of the UART signal. The external device

checks that the data is the same as the previously sent data. If the data is the same, it sends an acknowledgement. If not, it sends

a non-acknowledgement string message.

2.1.1 Read Tag Command

This command is used to start a read.

‘reTWWXYZ’

ASCII letters ‘re’ start the read command. The following table lists the appropriate values for the other characters. It is not

2.1.4 Calibration Commands

2.1.4.1 Programming Transponder Parameters

Transponder delay parameters P0, P1 and P2 determine the length of time for writing 0, 1 and a gap value to the transponder

(T55XX) when the transponder is programmed. In the SMRFID software these parameters are entered in microsecond format. The

software then automatically calculates the parameters that are necessary to be sent to the chip. Parameters are determined

according to type of transponder used (T55xx) and the inductor. See individual transponder datasheets for more information.

These parameters determine the delays. The built-in delay function for each parameter is determined by the to following formula:

12KL + 20K + 8

= Delay

(1)

24000000

For a 100 µs delay, values of K = 26 and L = 6 work. First use the ‘progrdly’ command string to begin. Next use the following

command to send parameter values to the RFID chip.

‘TUWXYZfr’

2.1.4.3 General System Parameters

There are four general system parameters for the RFID Chip and transponders:

•

R-ADF

P-ADF

WDR

FPAT.

They are listed and described below.

R-ADF : This value determines the frequency when antenna is being driven and attempting to read a transponder. The frequency

is determined by a PWM. The input clock for the PWM is 24 MHz. For a desired output frequency, the following formulae should

be applied.

24MHz

OutputFrequency

OutputFrequency =

−1

(2)

(3)

Period

PulseWidth =

(integer part)

2

If a 125 KHz output frequency is desired, the period should be 191 and pulse width 96. These values are then converted into

hexadecimal numbers and sent to the RFID chip.

P-ADF : This value determines the frequency when the antenna is being driven and attempting to write to a transponder. The

frequency is determined by a PWM. The input clock for the PWM is 24MHz. For a desired output frequency, the following formulae

should be applied.

CY8C0104 and CY8C0105

Preliminary Data Sheet

WDR: This value determines the period for a Watchdog reset. This value can be set to between 2 and 240 seconds. A hardware

reset occurs after each period. Note, the accuracy of the WDR period is low.

FPAT: This values determines the period for driving time of antenna when low power read mode is used. There is an internal

sleep timer adjusted to 1 second. When low power mode is selected, the reader is active. The antenna is driven in full power

mode for the value of the FPAT parameter times 7.5 ms, then enters sleep again.

For example, if FPAT is 20, the reader will wake up for 150 ms then re-enter sleep if a transponder is not detected. This process

occurs once per second. Current consumption is between 50 and 100 mA for the 150 ms period and between 20 and 70 uA during

sleep.

The following command string should be sent to the RFID chip to program the four parameters listed above:

‘TUWXYZfr.’

Table 4-17 lists the values for each parameter.

2.1.4.3.1 General Parameters Example

To program the RFID chip with a R-ADF of 122448Hz, a P-ADF of 125654Hz, a 2-second WDR, and an FPAT of 60, first send the

‘systmset’ command, then the following data:

char(0xC3) + char(0x62) + char(0xBE) + char(0x5F) + char(0x02) + char(0x3C) + ‘fr’

= ‘Ãb□<¾_fr’ (This is what the designer sees in the text box).
