1 Introduction 1.1 Overview The OEM050 is designed to offer iCLASS technology to a wide variety of service providers in applications such as vending machines, biometric readers, card printers, time and attendance terminals, alarm panels etc. A compact mechanical design with the power to drive antennas for read ranges up to 6.0” are the hallmarks of the OEM050. With only a two-wire serial interface and a regulated power supply, an OEM can have the power of iClass at their fingertips.
Specifications 1.3 Form Factor The OEM050 consists of 3 separate PCB’s; A reader PCB, a 80mm square antenna PCB with a 50Ω matching network, and a 34mm x 48mm antenna PCB with a 50Ω matching network. Both antenna PCB’s are sold separately. Figure 2.1 shows the dimensional outline of the reader PCB. 0.050 0.100 Connector P1 Pin 1 Connector P2 Pin 1 0.100 0.250 1.000 1.100 0.100 TYP MCX Style Coax Connector 1.100 1.200 Figure 2.
I/O Functionality Connector Pin # Pin Name Function P1 3 Serial Transmit Transmit pin for serial communications. May connect to an off-board RS-232 driver or directly to a uprocessor UART. P1 4 Serial Receive Receive pin for serial communications. May connect to an off-board RS-232 driver or directly to a uprocessor UART. P1 5 +5VDC Return Return for the +5VDC supply. P1 6 +5VDC Separate supply for uprocessor and other 5V circuitry.
I/O Electrical Specifications Pin Name Nominal Values Voltage Notes Current Power On Reset The minimum VDD rise time for the processor is 0.050V/ms. In the event that VDD ramps up at a slower rate a delay circuit has been provided based on the Microchip application note that consists of a diode, capacitor, and 2 resistors. Due to limitations in space and component size this protection may prove to be inadequate in some applications.
