MTI M200-RS Overview, 100% RS2000 Compatible
The MTI M200-RS module is pin-to-pin, 100% compatible with
Impinj®Indy® RS2000, a surface mount module that comprises a
completely integrated reader solution for EPC Gen2 / ISO18000-63
(formerly 18000-6C) applications. The module was developed to
make embedding a high performance reader easy. The MTI M200-
RS module based on Impinj’s Indy and R2000 builds on market-
leading Indy reader chip technology and integrates all of the
necessary components into a small package. Just provide power,
UART connection from a host, an antenna, and start reading tags.
It is fully tested and is certified for modular operation under FCC
and IC regulations. The M200-RS comes in a surface mount
package designed towork as aSMT (surfacemount technology) component in astandard
PCB manufacturing process.
This document provides hardware developers technical guidance to ensure optimal
performance when using the M200-RS.

2M200-RS Hardware Interface
An example M200-RS system-level block diagram for an embedded system is shown in
Figure 1. This figure shows the electrical connections that may and must be made to
control the M200-RS. Inthe figure, the required connections are illustrated with solid lines.
Recommended and optional connections are illustrated with different dotted and dashed
line patterns. They are also listed below.
More details for each connection are listed in the following subsections.
Figure 1 –Example M200-RS Block Diagram
Required connections:
•VDC_IN and GND are required to power the M200-RS.
•ANT1, ANT2, UFL1, or UFL2 are required to connect to UHF RFID antennas. Only
one is required for RFID activity, but all four may be used.
•UART1 Tx and Rx are required to communicate with the system host.
•ENABLE is used to enable or disable operation of the part. If this pin is driven low, the
power supplies in the part will be disabled. M200-RS may be reset by toggling this pin.
This pin must be driven high to enable the part.
Recommended connections:
•UART2 Tx and Rx may be used to examine debug information.
•HEALTH toggles to indicate successful operation of the M200-RS. Connection to an
LED provides a visual indication of whether or not an error condition exists.

Revision 1.4, Copyright © 2020, Microelectronics Technology, Inc. 5
•STATUS toggles to provide an indication when the M200-RS is in active mode (for
example, inventorying tags). Connection to an LED provides a visual indicator of the
device’s activity.
Optional connections:
•GPIOs allow interaction with the M200-RS as both digital inputs and outputs. They
may be used to trigger inventory, generate events based on inventory activity, or
provide general-purpose user-controlled digital I/O.
•WKUP provides a mechanism to wake up the M200-RS from the low power modes.
WKUP is also used to force entry into the Impinj firmware bootstrap. If unused, this
pin should be tied to logic low.
No connect:
•CLK_OUT, DTEST0 and DTEST1 connections are reserved for MTI use only.

2.2 Power Supply
M200-RS is powered by a voltage applied to the VDC_IN pins (pins 1 and 11) relative to
the GND pins. The supply voltage operating range is 3.2 V to 5.25 V. Average current
consumption varies from about 1600 mA (8 W) to about 1 µA (5 µW) depending on the
operating mode. Peak current consumption can exceed this by up to 50% depending on
the operating mode. The power supply is internally bypassed and regulated, and no
external bypass or bulk storage capacitance is required, as long as the input voltage is
stable.
If M200-RS activity is not required at all times, and power reduction is desired, the
ENABLE input can be driven low to place the part in “shutdown” mode, where the internal
power supplies are disabled, and no activity takes place. Otherwise, ENABLE should be
driven high.
2.3 RF Connections
The M200-RS has four RF antenna ports, which may be connected to 50 Ω antennas via
50 Ω controlled impedance connections. These connections could simply be microstrip
transmission lines to PCB antennas or SMT antennas, or they could include connectors
and coaxial cable. The RF connections are single ended, referenced to ground.
For more information about impedance matching, see section 3.1 - PCB Layout for RF.
Among the four ports, there are two SMT connections on the edge of the M200-RS
module, and two UFL connectors on the top side of the M200-RS module. All four may
be used in a design, allowing up to four antennas with no external switching. The
connectors are numbered in increasing order moving towards the corner of the module
with the cutout in theshield. This isshown in Figure 3. The antenna numbering convention
used in the IRI libraries is shown in Table 2-2.
If more antenna connections are required, external RF switches may be used to increase
the number of connections.

2.4 UART Communication
The M200-RS has two full-duplex UART interfaces at the pins, accessible using pins
UART1-RX, UART1-TX, UART2-RX, and UART2-TX. UART1 implements the host
communication interface via IRI, and UART2 implements thedebug interface. The Tx pins
are outputs from the M200-RS, and the Rx pins are inputs to the M200-RS. Both UART
interfaces are 115,200 baud, with 8 data bits, 1 stop bit, and no parity bit (8-n-1
configuration).
Each of the UART interfaces signals at 3.3V relative to GND. The TX pins are driven
strong high and low with a sink/source current of about 2 mA. If the load on a pin draws
more than the 2 mA sink and source current, the pin is not guaranteed to meet the VOH
and VOL specs. Excessive current sunk or sourced on the GPIO pins can also cause
electrical damage to the device.
Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not
be applied to the UART pins. This can cause permanent damage to the device.
Note Tag read rates can be limited by host communication interface baud rate. The
default baud rate of 115,200 Baud will limit the tag read rate to approximately 300 tags
per second.
2.5 Enable Pin
The M200-RS has an ENABLE pin (pin 9) allows an external signal to put the module in
Shutdown mode, which offers the lowest possible current consumption. The Enable pin
can also be used to restart the module.

MTI M200-RS Hardware User’s Guide
Revision 1.3, Copyright © 2020, Impinj, Inc.
Revision 1.4, Copyright © 2020, Microelectronics Technology, Inc. 10
The Enable pin has an internal 100 kOhm pull-down resistor. If the signal is above 1.2 V,
the module will be enabled, and if it is below 0.4 V, it will be disabled. This means that
the driving signal needs only source ~12 µA to enable the module. If the host device has
a pull-up drive mode, or a series resistor is used with a strong drive mode, the resistor
value should be selected such that the Enable voltage is above 1.2 V. This arrangement
is shown in Figure 4, and the resistor size requirement is shown in Equation 2-1.
Note Using a series resistor or resistive pull-up drive mode allows the same circuit to be
used to drive the RS500 NRST pin and the M200-RS ENABLE pin.
The module can be reset by toggling the Enable pin low and then back high.

2.6 Health and Status Pins
The M200-RS has two pins that indicate the state of the device through their voltages:
HEALTH (pin 23) and STATUS (pin 22).
Both pins are outputs operating at a logical voltage level of 3.3 V, and can sinkand source
2 mA each. If the load on one of these pins draws more than the 2 mA sink and source
current, the pin is not guaranteed to meet the VOH and VOL specs. Excessive current
sunk or sourced on the pins can also cause electrical damage to the device.
For recommendations on LEDs for observing the Health and Status pins, see section 3.3
-LEDs for Health, Status, GPIOs.
2.6.1 Health Pin Behavior
The HEALTH pin indicates whether the M200-RS is operating in its normal mode, or if
some other condition exists. The pin is cycled high and low in specific patterns to indicate
the state of the M200-RS. Those patterns are as follows:
M200-RS
