1. Product Overview

ZS3L is a low-power embedded Zigbee module that Tuya has developed. It consists of a
highly integrated RF processor chip (EFR32MG21A020F768IM32-B) and several
peripheral components, with an embedded 802.15.4 PHY/MAC Zigbee network protocol
stack and robust library functions. ZS3L is embedded with a 32-bit low-power Arm
Cortex-M33 core, 768 KB flash memory, and 64 KB random-access memory (RAM), and
has extensive peripherals.
ZS3L is a FreeRTOS platform that integrates all the function libraries of the Zigbee MAC
and TCP/IP protocols. You can develop embedded Zigbee products as required.
