Introduction to ZigBee Module--TYZS1

ZigBee module introduction–TYZS1

1. Product overview

​ TYZS1 is a low-power embedded Zigbee module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of one EFR32MG13P632 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 stack and rich library functions. The TYZS1 embeds a low-power 32-bit ARM Cortex-M4 core, 512KByte Flash program memory, 64KB RAM data memory, and a wealth of peripheral resources.

​ TYZS1 dimensions: 16mm (W) x 24mm (L) x 3.5mm (H). The TYZS1’s dimensions are shown in Figure 2:

2.2 Pin definition

​ Interface pins are defined as shown in Table 1:

​ Table 1, TYZS1 interface pins description

Pin number Symbol IO type Function
1 nRST I Hardware reset pin, the chip is reset when the pin is LOW; The module comes with a power-on reset and the user can use this pin as needed
2 ADC AI ADC port (1), 12-bit precision SAR analog-to-digital converter
3 NC - NC pin, external handling is not required
4 GPIO0 I/O GPIO pin usage.
5 SWO I/O GPIO pin usage/can be used as an output pin under JLINK communication.
6 PWM3 I/O GPIO pin usage.
7 PWM1 I/O GPIO pin usage.
8 VCC P Module power supply pin (common supply voltage : 3.3V)
9 GND P The reference ground of the module.
10 GPIO2 I/O GPIO pin usage.
11 SWDIO I/O JLINK SWDIO programming pin. Can be used as a GPIO pin in normal applications.
12 SWCLK I/O JLINK SWCLK programming pin. Can be used as a GPIO pin in normal applications.
13 PWM2 I/O GPIO pin usage.
14 GPIO3 I/O GPIO pin usage.
15 RXD I/O UART0_RXD
16 TXD O UART0_TXD

Description: P indicates the power pin, I/O indicates the input/output pin, and AI indicates analog input pin.

​ RST is only the module hardware reset pin; it cannot clear Zigbee net-pairing information.

​ (1) : 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.

2.2 Test point definition

​ Test pins are defined in Table 2:

5. Antenna signal

5.1 Antenna type

​ The default PCB onboard antenna access/reserved Ipex connector is used to extend the high gain external antenna in complex installation environments.

5.2 Antenna interference reduction

​ To optimize Zigbee performance of the wireless module in combination with the PCB onboard antenna, it is recommended to keep the antenna at least 15mm from other metal parts. It is recommended that the corresponding antenna area of the adapter board be hollowed out for the best effect.

​ The user PCB board should not be routed around the antenna area and should not be covered with copper to avoid affecting the antenna radiation performance. For the module PCB onboard antenna area, refer to Figure 3 below, “TYZS1 mechanical dimensional drawing”.
