Product introduction
The UHF high-power module SIM7200 is a high-performance UHF RFID read-write module developed by the technology team of Xinliangzhan based on the new generation of IMPINJ RF chip E710. It is specially designed to meet the requirements of high-performance RFID handheld devices, mobile or portable RFID devices. The SIM7200 module provides one MMCX antenna interface, supporting up to 33 dBm RF output. This module has the characteristics of low power consumption, small size and high sensitivity. Combined with the advanced multi tag algorithm of Xinliangzhan, it is a priority for RFID mobile devices.
Product features
New generation E710 RF chip
Impinj new generation E710 UHF RF reader chip is adopted, which has high
sensitivity, wide reading range, low power consumption and strong performance.
Super tag reading performance
The tag reading speed is fast, the reading is stable, the multi tag anti-
collision ability is strong, and the reading distance is long. When using the
4dBi four wall spiral antenna, the reading distance is more than 9 meters, and
the multi tag reading speed is fast, up to 900 pieces/second.
Lower power consumption
It can work normally in the 3.6V low voltage mode. The maximum power output
power consumption is 6.5W, and the standby power consumption is only 0.25W.
The excellent low power consumption design makes the product have a longer
service life.
Multiple monitoring functions and excellent stability
The module supports label RSSI detection, antenna connection status detection,
and working temperature detection. Multiple data detection is more convenient
for users to use efficiently; The module can work stably in the ambient
temperature of -20℃ to+65℃, and supports stable operation in the ambient
humidity of 5% – 95%. It has high efficiency and stable performance and can be
applied to a variety of harsh working environments.

The application of information
The input power
It is recommended to filter the VCC port with a capacitance of 100~470uF to
reduce the traction to the power supply caused by the quick opening and
closing of the power amplifier during RF tran smission. 0.1uF/100pF capacitors
filter out power supply ripple in different frequency bands. Since the current
is high when the module is working at full power, the module may not work sta
bly when the battery is low when the handheld device is powered directly by
the battery, so it is r ecommended to boost the VCC to 5V.
Enable or reset EN is enabled, with built-in pull-up resistance (100k) to VCC.
When the module is powered on at high level or suspended, the module will be
powered off when it is connected to low level (low leve l should be less than
0.4V, high level should be greater than 0.9V and less than VCC).
Rst reset, built-in pull-up resistance to 3.3V, reset when connected to low
level.
GPIO interface
Input:
Logic low ＜ 0.8V minimum 0V
Logic high ＞2 V Maximum 3.3 V
Output:
Logic Low maximum 0.4V
Logic High has a minimum of 2.9V and a maximum of 3.3V
The maximum output current of the I/o port is 5mA.
The antenna connection
The output impedance of the antenna port is 50 ohms, and the antenna standing
wave ratio is rec ommended to be less than 1.5. A better antenna standing wave
ratio can get better card reading effect.
Communication interface (rxd/txd)
The communication interfaces RXD and TXD are at TTL level, and the default
baud rate is 115200b ps
