Global Intelligent Platform
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.

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.
2
FRC_DCLK
I/O
Packet trace interface (PTI) clock signal.
3
SWDIO
I/O
J-Link SWDIO programming pin. It can be configured
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
