General Description
The EVB90109 is an assembled module that allows evaluating the advantages of the MLX90109 transceiver IC. 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.

Introduction
 The PCIB40 is an 8-bit ISA bus add-on board providing 40 channels of digital I/O and three 16 bit counter/timers.
The digital I/O is organised into 5 groups of 8 bits. Each I/O channel may be configured as an input or an output.
The board also includes the facility to define the powerup/reset state of a group of output bits.
This is extremely useful in ensuring the safe start-up of a PC-controlled system.
The 3 counter/timers are implemented using the industry-standard 8254 device.
One timer can be used as a periodic interrupt generator while the other two timers can be connected to external signals for frequency measurement and pulse generation.
The D-50 I/O connector conforms to Arcom’s standard Signal Conditioning System (SCS) and may be used to drive a range of Signal Conditioning Boards (SCB); see Arcom’s PCbus catalogue for more details.

Features
* CE compliant design
* 40-channel digital I/O
* Three 16-bit counter/timers with max count rate (input and output) 1MHz
* Compact I/O addressing scheme (link selectable base address)
* Link-selectable interrupt options (IRQ2,3,4,5,7)
* Each channel has a current sink capability of 24mA @ 0.45V and source current of 500mA @ 2.7V
* Bit programmable for input or output
* Group selection of powerup/reset state.
* Board access LED (for all decoded addresses)
* User controlled LED
* 8-bit bus interface
* I/O connector conforms to Arcom Signal Conditioning System (SCS)
* Operating temperature range, +5°C to +55°C
* Power consumption from the host, max 300mA @ +5V
* MTBF: 477,000 hours (using generic figures from MIL-HDBK-217F at ground benign)
