Geehy Introduces Its First Dual-Mode Bluetooth® 5.2 Wireless MCU GW3323


Geehy announced its first low-power dual-mode Bluetooth 5.2® chip GW3323, which is based on a 32-bit high-performance RISC-V core, supports DSP instructions and external memory expansion and is compatible with 5.2 Bluetooth low energy protocol and classic Bluetooth SPP. It is also suitable for a wide range of IoT applications with Bluetooth wireless connectivity, such as thermal printers, smart watches, Bluetooth headsets, vacuum cleaners, audio equipment, etc.



Dual-mode Communication Protocol with Wide Applications

Support SPP+BLE Bluetooth dual-mode communication protocol, the measured BLE rate is 30KB/s, and the SPP rate is 80KB/s, which enables strong anti-interference ability. The 160MHz high frequency can handle a large number of high-performance computing. Equipped with 1MB Flash and 256KB SRAM large-capacity memory, it meets more product development needs.


Rich Peripherals with High Integration

Designed to reduce the size of the whole device, it integrates a high-performance 2.4GHz RF transceiver, 24 I/Os, 16 10-bit ADCs, 2 12-bit DACs, and rich communication interfaces such as USART, I2C, USB, SPI, etc., which can save BOM cost and PCB area to the greatest extent, and help customers reduce product production costs.


Built-in PMU with Low Power Consumption and High Sensitivity

Built-in power management unit PMU with Charger/Buck/LDO can charge the battery on the Vbat pin through the Vusb pin, the charging current up to 0.2A, which can maximize the battery life. The receiver sensitivity under 2Mbit/s EDR is -94dBm, the maximum TX output power is 9dBm, and the operating temperature range is -40  ~ +85 .


The new GW3323 is now in mass production and is equipped with complete development tools and technical materials such as datasheets, development boards, programmers, SDK routines, and a free open platform to support customers in rapid, efficient, and convenient production in the mass production process.
