1 Product Overview

BT7L-IPEX is an embedded Bluetooth low energy (BLE) module that Tuya has developed.

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

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

library functions. BT7L-IPEX also contains a low-power 32-bit multipoint control unit

(MCU), BLE 5.0 component, 2.4 GHz radio component, 4 MB flash memory, 48 KB static

random-access memory (SRAM), and nine multiplexing I/O interfaces.

1.1 Features

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

processor

⚫ Dominant frequency: 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: nine pulse width modulation (PWM) interfaces

 BLE RF features

⚫ Compatible with BLE 5.0

⚫ Up to 1 Mbit/s RF data rate

⚫ TX power: +10 dBm

⚫ RX sensitivity: –94.5 dBm at BLE 1 Mbit/s

⚫ Embedded advanced encryption standard (AES) hardware encryption

⚫ External IPEX antenna with 2.5 dBi gain

⚫ Working temperature: –20°C to +85°C

BT7L-IPEX Datasheet 5.2 Antenna Interference Reduction To ensure optimal RF performance, it is recommended that the antenna be at least 15 mm away from other metal parts. If metal materials are wrapped around the antenna, the wireless signals will be reduced greatly, deteriorating the RF performance. Because BT7L-IPEX is inserted to the PCB, sufficient space needs to be reserved for the antenna. 6 Packaging Information and Production Instructions 6.
