BT5S Module Datasheet 1 PRODUCT OVERVIEW

1 Product Overview

BT5S is an embedded Bluetooth low energy (BLE) module that Tuya has developed.

It consists of a highly integrated Bluetooth chip (TLSR8250F512ET32) and several

peripheral circuits, with an embedded Bluetooth network protocol stack and robust

library functions. BT5S also contains a low-power 32-bit microcontroller unit (MCU),

BLE 5.0 or 2.4 GHz radio, 512 KB ﬂash memory, 48 KB static random-access memory

(SRAM), and six multiplexing I/O pins.

1.1 Features

• Embedded low-power 32-bit MCU, which can also function as an application

processor - Clock rate: 48 MHz

• Working voltage: 1.8 V to 3.6 V (Under 1.8 V to 2.7 V, the module can start

but the RF performance is not guaranteed. Under 2.8 V to 3.6 V, the module

performance is normal.)

• Peripherals: one Inter-Integrated Circuit (I2C) bus, four pulse width modulation

(PWM) pins, and one universal asynchronous receiver/transmitter (UART)

• BLE RF features - Compatible with BLE 5.0 - RF data rate: 1 Mbit/s or 2 Mbit/s

- TX power: +10 dBm - RX sensitivity: –94.5 dBm at BLE 1 Mbit/s - Embed-

ded Advanced Encryption Standard (AES) hardware encryption - Onboard PCB

antenna - Working temperature: –20°C to +85°C

1.2 Application Scenarios

• Smart households

• Smart low-power sensors
