TYZS1L User manual
Version1.0.0 1
1. Product Overview
 The TYZS1L is a low-power embedded Zigbee module developed by Hangzhou Tuya 
Information Technology Co., Ltd. The module consists of a EFR32MG13P732HI highly 
integrated wireless RF processor chip and a small number of peripheral devices. It has a built-in 
802.15.4 PHY/MAC Zigbee network protocol and a large number of library functions. The 
TYZS1L embeds a low-power 32-bit ARM Cortex-M4 core, 512KByte Flash program memory, 
64KB RAM data memory, and a wealth of peripheral resources. 
The TYZS1L is a FreeRTOS platform that gathers all Zigbee MAC and TCP/IP libraries into 
one place. It enables users to build on the product and develop embedded Zigbee products that suit 
their individual needs.

2.2 Pin definition 
Interface pins are defined as shown in Table 1: 
Table 1, TYZS1L interface pins description 
Description: P indicates the power pin; I/O indicates the input/output pin; AI indicates 
analog input 
pin. 
nRST is only the module hardware reset pin; it cannot clear Zigbee net-pairing 
information. 
AI: This pin can only be used as an ADC port. It cannot be used as a normal IO port. If it 
is not used, it needs to be left floating. 
 As an ADC input, the input voltage range is limited to 0-AVDD and can be configured by 
software.
