TYZS7 Module

Scope of application

This topic describes relevant information about the TYZS7 module during MCU connection development.

TYZS7 is a low power embedded Zigbee module developed by Tuya Smart. The module consists of a highly integrated radio-frequency identification (RFID) chip EFR32MG13P732 and a few peripheral components, with a built-in 802.15.4 PHY/MAC Zigbee network protocol stack and various library functions. TYZS7 also has a low power 32-bit ARM Cortex-M4 processor, 512 KB flash, 64 KB RAM, and rich peripheral resources.

As a FreeRTOS platform, TYZS7 integrates all function libraries of Zigbee MAC and TCP/IP protocols. You can develop your own embedded Zigbee products.

Design specification

• Module power supply:

  • The maximum transmitting power consumption of the module reaches 118 mA. It is recommended that the supply current of the module should exceed 200 mA, and the total capacity of the external filter capacitor should exceed 10 uF.
  • In the PCB layout, the filter capacitor at the power input pin shall be arranged near the power supply pin.

• Module pin:

  • The nRST pin only resets the module hardware, but cannot clear Zigbee pairing information.
  • The ADC port cannot be used as an ordinary I/O port. When not in use, the pin can float. As the ADC input port, the input voltage ranges from 0 V to AVDD, which is configured in the software.

• Radio frequency (RF) of the module:

  When an IPEX external antenna is used, it is recommended that the distance between the antenna and other metal parts should be at least 15 mm, in order to optimize the wireless performance. Do not wrap metal parts around the antenna, in order not to affect antenna performance. It is recommended to hollow out the adapter board in the antenna area.
