1 Product Overview
BT7L-G 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-G 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 2 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
⚫ Onboard PCB antenna with 2.5 dBi gain
⚫ Working temperature: –20°C to +105°C
