It will facilitate the starts of RFID applications and can be implemented in a compact way, with minimum development time, and minimum final system cost. All pins of the MLX90109 reader are available on a DIL socket for easy control with an external microcontroller. Two extra pins have been added for extended control options on the voltage on the MODU pin.The EVB90109 can be used as a 125 kHz reader, to read out the load modulation from a transponder. It can also be used to send information to a transponder using On/Off keying modulation. For fast protocol which required fast fall time on the reader’s antenna, the EVB90109 includes a “Fast decay” circuit composed of an external transistor and diode in parallel on the antenna. This circuit is accessible through a digital pin on the DIL-10 connector.Table of Contents1 EVB90109 ELECTRICAL SPECIFICATIONS (3)2 DESCRIPTION (3)2.1G ENERAL EXPLANATION (3)2.2P ARALLEL ANTENNA (4)2.3M ODULATION NETWORK (4)2.4A NTENNA VOLTAGE IN READ OPERATION (4)2.5N OISE CANCELLATION IN READ OPERATION (5)2.6A NTENNA VOLTAGE IN 100% MODULATION OPERATION (5)2.7F AST DECAY CIRCUIT (6)3 SCHEMATIC (7)4 PHYSICAL OUTLINE (8)5 PINNING OF THE EVB90109 (9)6 COMPONENTS (9)7 DISCLAIMER (10)1 EVB90109 Electrical Specificationsreduce the fall time of the antenna. For more information, please refer to the application note “100% Modulation (On/Off keying)”. An additional footprint of “Modulation network” is available on the board and is accessible through the MODUR3 digital connection. All others digital connections as SPEED, MODE, MODU, CLOCK and DATA, are available on the DIL-10 connector.Figure 1: EVB90109Note: The EVB90109 does not include any pull-up resistors on the digital connections DATA and CLOCK. This must be done externally, by configuring the IO ports of a microcontroller in pull-up mode, or by adding two external resistors connected between the digital pins and Vdd.Parallel resonant antenna (L, C4, C5) Fast decay circuit (Q1, MLX90109Modulation Network (R1, R2)Connector DIL-102.2 Parallel antennaThe parallel antenna of the EVB90109 consists of the inductance (L) based on the MLX90125 reader coil and the tune capacitor (C4), which form a resonant system at 125 kHz with a total (inductance and capacitance) antenna impedance of about 1.3kOhms. The MLX90109 is specified to drive a minimal antennabe smaller margin in theof the antenna to work with a high quality factor and then to get the maximum of operating distance.2.3 Modulation networkThe modulation network is used to set the voltage on the MODU pin of the MLX90109. As shown in the following formula, the voltage on the antenna can be adjusted according to this voltage. This features can be used to reduce the power consumption of the chip by setting a lower voltage on the antenna. Under no circumstances it can be used to make proportionnal modulaiton, due to internal feedback loop which doesn’t allow this use.overshoot MODU DD ant V V V V −−=The EVB90109 is provided with two resistors R1 and R2 as the modulation netwok controlled through the pin MODUR2 to set the voltage on the antenna respectively On (Vmodu to 0.8 Volts) and Off (Vmodu to 5 Volts). Others footprint C1, C3 and R3 and an extra pin MODUR3 are available on the board and can be used for specific applications.2.4 Antenna voltage in read operationThe resistors R1 and R2 set VMODU to 0.8V (1V for full temperature range [–40, 85] C) which is the lowest possible voltage to guarantee that the antenna driver of the MLX90109 stays out of its linear operating zone. The field is set On (VMODU to 0.8V) and Off (VMODU to VDD) when applying 0V and VDD on pin MODUR2.2.5 Noise cancellation in read operationThe resonant antenna is a natural band-pass filter, which becomes more effective as Q ant increases.The MLX90109 has an internal first order filtering of the envelope that changes according to the setting of the SPEED pin to fit to the biphase and Manchester data spectrum:Note:mode.The modulation network R1 and R2 can be used to set the voltage amplitude on the antenna On and Off by applying 0 Volts and Vdd on the pin MODUR2.Switching ON the magnetic field depends on the internal driver of MLX90109 and takes less than 5 carrier periods. Switching OFF the magnetic field depend on the quality factor (Qant) of the parallel antenna connected to the reader (about 24 periods with the EVB90109). To reduce this fall time, the “fast decay” circuit can be used.2.7 Fast decay circuitVery small fall time may be required in fast protocol, to be understood by the transponder in the field. This is why, the EVB90109 include a “fast decay” circuit controlled through the pin FAST_DECAY and composed of the transitstor Q1 and the diode D1. The following picture shows how to implement the “fast decay” system.Picture 1: Fast Decay module control, (1) Antenna, (2) MODUR2, (3) FAST_DECAY3 SchematicThe following diagram shows the schematic of the EVB90109.

6、在将主板与电源连接前，请确认电源电压值。

7、请将电源线置于不会被践踏的地方，且不要在电源线上堆置任何物件。

8、当您需连接或拔除任何设备前，须确定所有的电源线事先已被拔掉。

9、为避免人体被电击或产品被损坏，在每次对整机、板卡进行拔插或重新配置时，须先关闭交流电源或将交流电源线从电源插座中拔掉。

10、请留意手册上提到的所有注意和警告事项。

11、为避免频繁开关机对产品造成不必要的损伤，关机后，应至少等待30秒后再开机。

12、设备在使用过程中出现异常情况，请找专业人员处理。

13、请不要将本设备置于或保存在环境温度高于70℃上，否则会对设备造成伤害。
