Mercury6e Introduction
The ThingMagic® Mercury6e® (M6e) embedded module is an RFID engines that you can
integrate with other systems to create RFID-enabled products.
Applications to control the M6e modules and derivative products can be written using the
high level MercuryAPI. The MercuryAPI supports Java, .NET and C programming
environments. The MercuryAPI Software Development Kit (SDK) contains sample
applications and source code to help developers get started demoing and developing
functionality. For more information on the MercuryAPI see the MercuryAPI Programmers Guide and the MercuryAPI SDK, available on the ThingMagic website.
This document is for hardware designers and software developers. It describes the
hardware specifications and firmware functionality and provides guidance on how to
incorporate the M6e module within a third-party host system. The rest of the document is
broken down into the following sections:
Hardware Overview - This section provides detailed specifications of the M6e
hardware. This section should be read in its entirety before designing hardware or
attempting to operate the M6e module in hardware other than the ThingMagic
DevKit.
Firmware Overview - This section describes provides a detailed description of the M6e
firmware components including the bootloader and application firmware.
Communication Protocol - This section provides an overview of the low level serial
communications protocol used by the M6e.
Functionality of the Mercury6e - This section provides detailed descriptions of the M6e
features and functionality that are supported through the use of the MercuryAPI.
Appendix A: Error Messages - This appendix lists and provides causes and suggested
solutions for M6e Error Codes.

The maximum RF power that can be delivered to a 50 ohm load from each port is 1.4
Watts, or +31.5 dBm (regulatory requirements permitting).
The RF ports can only be energized one at a time.
FCC/NA Region max RF power is 30 dBm. For 31.5 dBm operation in the

Antenna Requirements
The performance of the M6e is affected by antenna quality. Antennas that provide good
50 ohm match at the operating frequency band perform best. Specified sensitivity
performance is achieved with antennas providing 17 dB return loss or better across the
operating band. Damage to the module will not occur for any return loss of 1 dB or
greater. Damage may occur if antennas are disconnected during operation or if the
module sees an open or short circuit at its antenna port.
Antenna Detection
To minimize the chance of damage due to antenna disconnection, the M6e supports
antenna detection. Detection can be done automatically or manually, the choice of which
is configured through API calls. Regardless of how itʼs used it is generally recommend
that antenna detection be enabled as it helps protect the module from possible damage
due to return losses less than 1 dB.
In order for antennas to be detected by the M6e the antenna must pass some DC current
across the center pin and ground, i.e. must present between 50 Ohms and 10 kOhms DC
resistance.

Power Consumption specifications apply to control via the TTL UART.
It is not recommended to use the TTL interface when planning to operate the
module in Tag Streaming/Continuous Reading mode. The TTL interface (both the
module side and the host side) cannot detect physical disconnections, as
can the USB Interface, simplifying reconnection.

The baudrate in the Boot Loader mode depends on whether the module
entered the bootloader mode after a power-up or through an assert or “boot
bootloader” user command. Upon power up if the Reset Line is LOW then the
default baud rate of 115200 will be used. If the module returns to the
bootloader from Application Firmware mode, then the current state and
baudrate will be retained.
USB Interface
Supports USB 2.0 full speed device port (12 Megabits per second) using the two USB
pins (USB_DM and USB_DP).
General Purpose Input/Output (GPIO)
The four GPIO connections, provided through the M6e Digital Connector Signal Definition,
may be configured as inputs or outputs using the MercuryAPI. The GPIO pins connect
through 100 ohm resistors to the high current PA0 to PA3 pins of the AT91SAM7X
processor. The processor data sheet can be consulted for additional details.
Pins configured as inputs must not have input voltages that exceed voltage range of -0.3
volts to +5.5 volts. In addition, during reset the input voltages should not exceed 3.3V.
Outputs may source and sink 16 mA. Voltage drop in the series 100 ohm resistor will
reduce the delivered voltage swing for output loads that draw significant current.
Input Mode
– TTL compatible inputs,
– Logic low < 0.8 V,
– Logic high > 2.0V.
– 5V tolerant
Output Mode
– 3.3 Volt CMOS Logic Output with 100 ohms in series.

– Less than 0.2 Volts when sinking 0.3 mA.
Module power consumption can be adversely affected by incorrect GPIO configuration.
Similarly, the power consumption of external equipment connected to the GPIOs can also

be adversely affected. The following instructions will yield specification compliant
operation.
On power up, the M6E module configures its GPIOs as inputs to avoid contention from
user equipment that may be driving those lines. The input configuration is as a 3.3 volt
logic CMOS input and will have a leakage current not in excess of 400 nA. The input is in
an undetermined logic level unless pulled externally to a logic high or low. Module power consumption for floating inputs is unspecified. With the GPIOs configured as inputs
and individually pulled externally to either high or low logic level, module power
consumption is as listed in the M6e Power Consumption
GPIOs may be reconfigured individually after power up to become outputs. This
configuration takes effect either at API execution or a few tens of milliseconds after power
up if the configuration is stored in nonvolatile memory. The configuration to outputs is
defeated if the module is held in the boot loader by Reset Line
configured as outputs consume no excess power if the output is left open. Specified
module power consumption is achieved for one or more GPIO lines set as output and left
open. Users who are not able to provide external pull ups or pull downs on any given
input, and who do not need that GPIO line, may configure it as an output and leave it
open to achieve specified module power consumption.

Configuring GPIO Settings
The GPIO lines are configured as inputs or outputs through the MercuryAPI by setting the

and gpoSet() methods, respectively. See the language specific reference guide for more

After that action is completed, this line is configured as an output line. While the unit
continues to be in bootloader the line is driven high.
Once in application mode, the RESET line is driven low. if the module returns to the
bootloader mode, either due to an assert or “boot bootloader”, the RESET line will again
be driven high.
To minimize power consumption in the application, the RESET line should be either left
open or pulled weakly low (1.5k Ohm to ground).

Power Requirements
RF Power Output
The M6e supports separate read and write power level which are command adjustable
via the MercuryAPI. Power levels must be between:
– Minimum RF Power = +5 dBm
– Maximum RF Power = +31.5 dBm (+/- 0.5 dB accuracy above +15 dBm)
Maximum power may have to be reduced to meet regulatory limits, which
specify the combined effect of the module, antenna, cable and enclosure
shielding of the integrated product.
Power Requirements
FCC regulations limit the maximum RF Power to 30 dBm in NA Region. For
31.5 dBm operation in the NA Region the M6e-A must be purchased.
Special RF Power Output Requirements for the M6e-A
Operation requires professional installation to correctly set the TX
power for the RF cable and antenna selected.
Power Settings for Authorized Antennas and Cables
The M6e-A has been designed to operate with the antennas listed in Authorized Antennas
list using the cables in the M6e-A Authorized Cables
and cable the maximum RF power is determined from antenna gain (Max Linear Gain
value from antenna list) and antenna cable loss (Insertion Loss value from cable list)
using the formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For example, for the Laird S8658WPL and the ThingMagic CBL-P6 6ft cable the following
calculation can be performed:

Minimum cable insertion loss = 0.8 dB
Pmax = 36 - 6 + 0.8 = 30.8 dBm
The maximum RF power that may be set using this configuration is 30.8 dBm (see
Warning above).
Power Supply Ripple
The following are the minimum requirements to avoid module damage and to insure
performance and regulatory specifications are met. Certain local regulatory specifications
may require tighter specifications.
5 Volt +/- 5%,
Less than 25 mV pk-pk ripple all frequencies,
Less than 11 mV pk-pk ripple for frequencies less than 100 kHz,
No spectral spike greater than 5 mV pk-pk in any 1 kHz band.
Operation in the EU Region (under ETSI regulatory specs) may need
tighter ripple specifications to meet ETSI mask requirements.
