Tuya Inc. V2.0.0

1 Product Overview

TYZS4 is a low-power embedded Zigbee module that Hangzhou Tuya Inc. has developed.

It consists of a highly integrated wireless radio processor chip

(EFR32MG1B232F256GM48-C0) and several peripheral components, with an embedded

802.15.4 PHY/MAC Zigbee network protocol stack and robust library functions. TYZS4 is

embedded with a low-power 32-bit ARM Cortex-M4 core, 256 KB flash memory, and 32

KB random-access memory (RAM), and has extensive peripherals.

TYZS4 is a FreeRTOS platform that integrates all the function libraries of the Zigbee MAC

protocol. You can develop built-in Zigbee products as required.

2 Module Interfaces 2.1 Dimensions and Footprint TYZS4 has two rows of pins with a 2 mm pin spacing. TYZS4 dimensions (H x W x D): 3.5±0.1 mm x 21±0.35 mm x 28±0.35 mm Figure 2-1 shows the TYZS4 front and rear views. Figure 2-1 TYZS4 front and rear views 2.2 Pin Definition Table 2-1 TYZS4 interface pins Pin No. Symbol I/O Type Function 1 nRST I Hardware reset pin. When the pin is at a low level, the chip is reset. TYZS4 is reset upon power-on, and therefore, this pin may not be used.

Pin No. Symbol I/O Type Function as a GPIO in actual application programs. 4 SWCLK I/O J-Link SWCLK programming pin. It can be configured as a GPIO in actual application programs. 5 SWO I/O Used as an output pin in J-Link debugging communication state or a GPIO in actual application programs. 6 PWM3 I/O Used as a GPIO. It supports Packet Traffic Arbitration (PTA). 7 PWM1 I/O Used as a GPIO. It supports PTA. 8 VCC P Power supply pin. The typical power supply voltage is 3.3 V.

5 Antenna Information 5.1 Antenna Type By default, TYZS4 uses an onboard PCB antenna. 5.2 Antenna Interference Reduction To ensure optimal wireless performance when the Zigbee module uses an onboard PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts and that the antenna location on the PCB be hollowed out. To prevent adverse impact on the antenna radiation performance, avoid copper or traces along the antenna area on the PCB, as shown in the following Figure 5-1.
