Hardware Overview
Introduction 23
WARNING!
The M5e antenna ports may be susceptible to damage from Electrostatic
Discharge (ESD). Equipment failure can result if the antenna or communication
ports are subjected to ESD. Standard ESD precautions should be taken during
installation and operation to avoid static discharge when handling or making
connections to the M5e reader antenna or communication ports. Environmental
analysis should also be performed to ensure static is not building up on and
around the antennas, possibly causing discharges during operation.
Hardware Overview
The following sections explain the M5e and M5e-Compact hardware, and their hardware
revisions.
Note
The M5e and M5e-Compact are the same except where specified that they
are different.
M5e and M5e-Compact Hardware
The M5e and the M5e-Compact are single board modules designed for more space-
constrained applications. The digital and analog electronics are on the same circuit
board. They use a custom RFID reader chip or Application Specific Integrated Circuit
(ASIC).
Microcontroller
The M5e and M5e-Compact have Atmel ARM7 microcontrollers with 256 kB of on-chip
flash memory for storage of all calibration and program data.
Electrostatic Discharge • IEC-61000-4-2 discharge direct to operational antenna port tolerates
max 300 Volt Pulse
• MIL-883 3015.7 discharge direct to operational antenna port tolerates
max 1200 Volt Pulse
Note: Survival level varies with antenna return loss and antenna
characteristics. See Appendix E: Environmental Considerations
for methods to increase ESD tolerances.
