  • Page 10: Micro-Reader Module

    www.ti.com General General The Micro-reader is an intelligent module providing RF and Control functions to read and program TIRIS transponders. It is equipped with a Serial Communications Interface (SCI) which may be directly connected to commonly used system controllers. The Micro-reader works together with a 47 µH, low-Q antenna, and therefore the system does not need tuning.

  • Page 11: Power Supply

    www.ti.com Product Description 1.2.1 Power Supply There are two separate 5V supplies to the Micro-reader, one for the output stage (VSP) and the other for the logic (VSL). On power up VSL should rise faster than 0.1 V/ms to ensure a reliable operation. The Micro-reader has an on-board reset circuit which will reset it should the supply fall below 4 V (±...

  • Page 12: Trigger Mode

    www.ti.com Product Description 1.2.4 Trigger Mode When the Micro-reader is in idle mode it is possible to trigger a single charge-only read with a power burst duration of 50 ms by taking the RDEN- pin to logic high for 100 µs. The single read will start on the falling edge of the 100 µs pulse.

  • Page 13: Micro-Reader Pin Connections

    www.ti.com Connector Pins Connector Pins The Micro-reader module has 30 pin connections which are shown in Figure 1-2 and listed in Table 1-1. Figure 1-2. Micro-reader Pin Connections Table 1-1. Pin Connections Signal Name Function SYNC Output for wired synchronization RDEN- Input for wired synchronization and single read trigger –...

  • Page 14: Pin Connection Description

    www.ti.com Connector Pins 1.3.1 Pin Connection Description SYNC (1) Output for wired synchronization. This output is at GND level until the Micro-reader starts its read cycle, at which time it goes to VSL until the complete reading, programming or locking cycle is finished. RDEN- (2) Input for wired synchronization.

  • Page 15: Block Diagram Of The Micro-Reader

    www.ti.com Connector Pins OKT (29) This output is set to logic high for approx. 60 ms if a valid transponder was read. It can be connected to an LED externally to indicate the result of the read cycle. STAT(30) Pin 30 is set to logic low when the RF-transmitter is activated. Supplying an external LED with this signal makes the status of the Micro-reader visible.

It also provides information about calculating the Q factor and adapting the inductance range. The antenna properties should be: Q factor less than 20 Inductance between 46 µH and 48 µH...

  • Page 46: C.3 Q Factor

    www.ti.com Q Factor Q Factor If the antenna’s Q factor exceeds 20: 1. The output capacitors will be overloaded and long term damage could result. 2. The antenna may still be resonating when the response from the transponder is received. Without built-in damping the data will not be correctly received.
