1.1 INTRODUCTION

This section provides the user a quick step-by-step instruction guide on how to set-up the MCP2030 Bidirectional Communication Demo Kit.

1.1.1 Transponder Unit

Connect power to the Transponder unit by inserting a 3V NiHM (CR2032) battery to the battery holder in the bottom side of the Transponder. When the Transponder is powered on, it is waiting for a 125 kHz low frequency (LF) command from the Base Station unit. On the PCB, there are three LF antenna coils: One large air-core coil on the bottom side and two ferrite-core coils on the top side. These three coils detect 125 kHz low frequency (LF) signals from x, y, and z directions. The Transponder also has a SAW (Surface Acoustic Wave) based UHF transmitter. A rectangular loop trace on the PCB is the UHF antenna. The Transponder has two LED diodes. A green LED (D6) will blink when the Transponder receives a valid LF command, and a red LED (D7) will blink when it transmitting an UHF response.

Supply power to the Base Station unit with a 9V - 18V power supply. As soon as the power is supplied, the LED D2 will light on, and the unit starts transmitting an LF command.The unit also waits for the responses from the Transponder at any time, except during the transmission of the LF command. When the unit receives a valid response from the Transponder, the LED D3 will blink and the received Transponder ID and RSSI (Received Signal Strength Indicator) value will be displayed on the LCD.

1.1.3 When both the Base Station and Transponder units are powered-on:

When the two units are powered-on, they will communicate by themselves. The Base Station sends a 125 kHz LF command and the Transponder responds to the command. When the Transponder is placed within about 2 meters to the Base Station unit, the two units may have a successful communication with each other and the Base Station unit will display the received Transponder ID and RSSI value on the LCD. This is called a bidirectional communication. User can test the RSSI by moving the Transponder within the Base Station’s LF field. The RSSI value will increase as the Transponder comes closer to the Base Station antenna and decrease as moves away from it. The two units are communicating with each other as long as the boards are powered. You can also test one directional communication from the Transponder to the Base Station unit by pressing button switch (SW3 or SW4) on the Transponder. The range of the one directional communication is about 20 meters.

This MCP2030 Bidirectional Communication Demo Kit shows you how to create a smart hands-free bidirectional communication system using the stand-alone MCP2030 and microcontroller. All MCU firmware used for both the Transponder and Base Station units are included in the CD ROM provided with the MCP2030 Bidirectional Communication Demo Kit. The user can easily modify the firmware for their own applications.

2.1 OVERVIEW

This section describes how to use the MCP2030 Bidirectional Communication Demo Kit.

The MCP2030 Bidirectional Communication Demo Kit consists of two Transponders and a Base Station unit. The Transponder consists of an MCP2030 (stand-alone three-axis analog front-end device), a PIC16F636, and an MCP3421(18-bit delta-sigma analog-to-digital converter). Unlike the existing PKE Reference Design System (P/N: APGRD001) from Microchip Technology Inc., this Transponder uses stand-alone devices for the bidirectional passive keyless entry (PKE) operation. This system also demonstrates the received signal strength indicator (RSSI) function using the MCP3421 delta-sigma ADC. When the Transponder receives a Base Station command, it transmits its ID and sampled RSSI value. By monitoring or mapping the RSSI values, the user can estimate location or motion of the transponder with respect to the Base Station unit. For example, for the automotive passive keyless entry (PKE) applications, the Base Station mounted inside the vehicle can determine whether the transponder is located inside or outside of the vehicle, or in the front or back seat in the vehicle.

The Base Station unit consists of a PIC18F4680, a low frequency (LF) power amplifier, an LF receiver section, a 434 MHz UHF receiver module, an LCD display, and CAN/LIN transceiver sections. The components in the LF receiver section and the CAN/LIN transceiver sections are populated on the PCB for future use, but their functions are not utilized for this demo version. Any user who needs these features can contact Microchip Technology Inc. for further information.

The MCP2030 Bidirectional Communication Demo Kit has been designed for easy modification by customers. The firmware of both the Transponder and Base Station units can be easily modified using the MPLAB

2.2 OPERATIONAL OVERVIEW

When the MCP2030 Base Station unit is powered on using a 9 V power supply and the MCP2030 transponder demo board is powered-on using a 3V lithium battery, the system works as follows:

(a) The Base Station unit transmits an LF command. Requesting the Transponder’s ID and RSSI data.

(b) When the Transponder receives the LF command, it transmits its 32-bit ID and RSSI data via the UHF (434 MHz) link.

(c) When the Base Station unit receives the response from the Transponder, it displays the Transponder ID and RSSI value on the LCD.

(d) The system repeats steps (a) through (c) as long as the power is supplied.

(e) If the button switch SW3 or SW4 on the Transponder is pressed, the Transponder transmits the button data (SW3: Unlock door, SW4: Lock door). The Base Station unit displays the button message on the LCD.

Figure 2-2 shows the communication sequence between the Base Station and the

Transponder units. Figure 2-3 shows the Base Station’s LF command and the demodulated data by the MCP2030.

3.2.2 Microcontroller (PIC18F4680)

The PIC18F4680 is used in this unit. The MCU provides an 125 kHz PWM for LF command and decodes incoming Transponder responses. If the response is valid, it displays the received data on the LCD and also blinks the LED D3. The PIC18F4680 has both a CAN controller and a LIN compatible EUSART features. The CAN and LIN transceiver components are populated on the Base Station Demo Board, but their functions are not implemented for this demo version.

3.2.3 433.92 MHz UHF Receiver Module

The Base Station Demo Board uses a 433.92 MHz AM super-regenerative compact hybrid receiver module. The AM UHF receiver receives the responses from the Transponder. The receiver has very high frequency stability over a wide operating temperature and tolerance of mechanical vibrations or manual handling. The AM receiver module has about -90 dBm of input sensitivity. The user can use their own receiver module of any frequency of interest as long as the frequency and modulation/demodulation method matches with those of the transmitter on the Transponder.

3.2.4 LCD

A standard 16 pin 2x16 monochromes LCD is used to display the response from the Transponder.

MCP2030 Bidirectional Communication Demo Kit User’s Guide

3.2.5 125 kHz Low Frequency Command Initiator

The 125 kHz PWM from the PIC18F4680 is power boosted by the MOS FET driver (TC4422). The PWM square pulse becomes a sine wave as the current passes through the LC series resonant circuit formed by L1 and C2, C3, and C4 on the Base Station Demo Board. The current that is passing through the L1 generates a magnetic field. When this magnetic field transmitted from the Base Station Demo Board is passing through the Transponder Demo Board’s antenna coil, it produces a voltage. This voltage is detected by the MCP2030 LF front-end device and the information carried on the voltage is processed by the PIC16F636 microcontroller on the transponder. See Recommended Reading for more details of the near-field magnetic coupling principles.

3.2.6 Power

Power can be supplied through J1 power jack. The voltage should be in the range of 9 - 18 VDC with a current rating greater than 500 mA.

3.2.7 MCU FIRMWARE ALGORITHM

The bidirectional communication method between the Base Station Demo Board and Transponder Demo Board is shown in Figure 2-2. The Base Station Demo Board sends an LF command, receives the responses from the Transponder Demo Board, and displays the received responses on the LCD. The Base Station Demo Board repeats the transmitting and receiving functions as long as its power supply is connected.

Figure 3-1 shows the LF command data format and waveform. The receiving data for-

mat is shown in Figure 3-5. The MCU firmware for the communication algorithm is included on the MCP2030 Bidirectional Communication Demo Kit CD ROM.

of the MCP3421ADC is 2.7V. For

The Transponder Demo Board uses a PIC16F636 microcontroller. This MCU is the same device that is used inside the PIC16F639 which is a dual die package device (PIC16F639 = PIC16F636 die + MCP2030 die in a single 20-pin package). The MCU interfaces with the MCP2030 stand-alone analog front-end device for LF communications and the MCP3421 delta-sigma analog-to-digital converter for RSSI data conversion. When the MCU is first powered-up, it writes the MCP2030 configuration registers and also writes the configuration register of the MCP3421 ADC (for 16 bit and one-shot mode).The MCP3421 stays in a low power standby mode after one conversion. The MCU also stays in a low power sleep mode while the MCP2030 is looking for a valid LF command.

The MCU is waken up by the demodulated output from the MCP2030 or by a button switch event (SW3 and SW4). The MCU decodes the demodulated output data from the MCP2030. If the data is a valid command, it blinks the green LED (D6) and reads the RSSI value by controlling the MCP3421 ADC. Once the RSSI value is acquired, the MCU feeds the transponder ID and the RSSI data into the 433.92 MHz UHF transmitter. The transmitted data from the UHF transmitter is detected by the RF receiver in the Base Station Demo Board and the data is displayed on the LCD.

When a button switch is pressed, the MCU feeds a corresponding data into the UHF transmitter. The red LED (D7) blinks each time the transponder transmits the UHF response. The red LED also blinks when the transponder receives invalid data.

3.3.3 Three-Input LF (125 kHz) Front-End (MCP2030)

The MCP2030 detects the Base Station Demo Board’s LF command using three LF antenna coils that are mounted on the Transponder Demo Board PCB. The Configuration registers of the MCP2030 are configured by the MCU when the Transponder Demo Board is powered up the first time, and are re-configured during operation. The MCU controls the MCP2030 for two different outputs: (a) Demodulated data and (b) Received Signal Strength Indicator output (RSSI). When it is detecting input signals, the device is configured for the demodulated data output. Once the MCU finds a valid LF command, then the MCU re-configures the MCP2030 for the RSSI output. In this case, the MCP2030 outputs the RSSI current that is proportional to the LF input signal

MCP2030 Bidirectional Communication Demo Kit User’s Guide

strength. This current output is fed into a resistor and the voltage across the resistor is fed into the MCP3421 ADC input pin. The converted16-bit ADC output is then fed into the MCU.

The function of the MCP2030 is controlled by its configuration register settings. Highly intelligent signal detection and response (bidirectional communications) is possible by utilizing the MCP2030 configuration register settings. The user can easily change or modify the included firmware for different settings of the MCP2030 configuration registers for their own applications.

3.3.4 UHF Transmitter (433.92 MHz)

A 433.92 MHz UHF transmitter is used to transmit the Transponder Demo Board data to the Base Station Demo Board. The UHF transmitter is based on a surface acoustic wave (SAW) resonator. The transmitter is turned on during the high duration of the data and off during the low duration of the bit data.

Note: The design and layout of this transmitter is not sufficient to ensure

compliance with EC or FCC regulations.

3.3.5 Analog-to-Digital Converter (MCP3421)

The Transponder Demo Board uses an MCP3421 ADC to convert the analog RSSI output of the MCP2030 to digital data. The MCP3421 is a delta-sigma analog-to-digital converter with 12, 14, 16, and 18 bit mode options. In this demo board, the converter is configured for the 16 bit and one-shot mode. When the transponder is powered-up, the MCU sends an I conversion. After one conversion, the device stays in a low power standby mode. During this mode, the device draws only about 1 µA. When the MCP2030 analog front-end device receives a valid Base Station command, then the MCU sends an I read command to the MCP3421 ADC for the analog-to-digital data conversion. At this moment, the Base Station Demo Board transmits a continuous LF signal for about 50 ms allowing the MCP2030 to collect the RSSI values. The RSSI voltage across the RSSI load resistor is fed into the MCP3421 input pin. After the MCU sends the I command, it is waiting for the MCP3421 to complete the conversion by checking the RDY

bit of the MCP3421 output. In typical operation, it takes about 50 ms to complete a 16 bit conversion. See Figure 2-2 and Figure 2-3 for more information on the ADC operation.

3.3.6 Programming of the Transponder

The Transponder Demo Board has a Programming Connector (J1) for In-Circuit Serial Programming™ (ICSP™). See Figure 3-3 for the J1 Programming Connector. The transmitter can therefore be re-programmed using the PICkit removing the microcontroller from the board.

3.3.7 Power

The Transponder Demo Board is powered by a standard Lithium 3V coin cell battery.

3.3.8 Microcontroller Firmware Algorithm

When the Transponder Demo Board is powered on, the PIC16F636 (MCU) programs the configuration registers of the MCP2030 and also the configuration register of the MCP3421 (ADC). After these set-up procedures, the MCU enters a low-power sleep mode while the MCP2030 is looking for a valid LF command. The MCU is waken-up by the demodulated output from the MCP2030 or button switch event. If the MCU receives a valid demodulated data from the MCP2030, then it transmits its 32 bit transponder ID followed by the 16 bit received signal strength indicator (RSSI) data. If the MCU is waken-up by a switch event (SW3 and SW4), it transmits the corresponding switch event data. The data is always attached to the header (See Figure 3-5). The Transponder ID is set to “04234567” and programmed in the EEPROM. The RSSI data is proportional to the LF signal strength. Therefore, the RSSI data increases as the Transponder Demo Board comes closer to the Base Station Demo Board. The Transponder Demo Board transmits each byte LSB first and also transmits a parity bit at end of each byte. See Figure 3-5 for more details of the Transponder Demo Board data stream. Figure 3-4 shows the firmware flow chart.

The MCU firmware is included in the MCP2030 Bidirectional Communication Demo Kit CD ROM.

Ex: For the transponder ID = 04234567 and acquired RSSI value = C6CF

Transponder ID = 04-23-45-67 = 00000100-00100011-01000101-01100111 Acquired RSSI Data = C6-CF = 11000110-11001111

Ex: Transmitting data with LSB first:

0010000P-11000100P-10100010P-11100110P-01100011P-1110011P

Where P = Odd Parity bit of the byte
