TUYA TYZS3 - User Manual

Tuya Inc. V2.0.0
1 Product Overview
TYZS3 is a low-power embedded Zigbee module that Hangzhou Tuya Inc. has developed.
It consists of a highly integrated wireless radio processor chip
(EFR32MG13P732F512GM48) and several peripheral components, with an embedded
802.15.4 PHY/MAC Zigbee network protocol stack and robust library functions. TYZS3 is
embedded with a low-power 32-bit ARM Cortex-M4 core, 512 KB flash memory, and 64
KB random-access memory (RAM), and has extensive peripherals.
TYZS3 is a FreeRTOS platform that integrates all the function libraries of the Zigbee MAC
and TCP/IP protocols. You can develop built-in Zigbee products as required.
Figure 1-1 shows the TYZS3 architecture.
