BM77SPP05双模蓝牙模块规格说明 V1.0.doc

Introduction

The ISSC BM77SPP05 Bluetooth module is design for Bluetooth standard SPP/ BLE electronic accessories via Bluetooth connectivity.

It is available in the 2.4GHz ISM band Class 2 Radio, compatible with Bluetooth Core Specification Version 3.0/ 4.0 + EDR.

ISSC IS1677NM single chip solution combines transceiver and baseband function to decrease the external components.

It narrows down the module size and minimizes its cost.

The optimized power design minimize power consumption to keep low battery.

 

Feature

- Bluetooth 3.0/ 4.0+ EDR compliant

- Low power 1.8V RF operation

- RF transmitter output power Class 2

- RF receiver GFSK typical -90dBm, π/4 PSK typical -90dBm, 8DPSK typical -83dBm, BLE typical -92dBm

- Internal ROM and 4Mibts of flash

- I2C for external EEPROM

- 1 LED driver
