company blog about EM9304V01LF28B Now Available in Large Quantities: A High-Performance SoC Designed Specifically for IoT and Bluetooth 5.0 Low Energy Applications

Shenzhen Mingjiada Electronics Co., Ltd. offers a long-term, large-volume supply of the EM9304V01LF28B—a highly integrated, low-power Bluetooth 5.0 RF SoC chip developed by EM Microelectronic. With its ultra-low power consumption, high integration, and powerful processing capabilities, this device is an ideal choice for battery-powered wireless connectivity applications such as Internet of Things (IoT) devices, smart home systems, industrial automation, and wearable devices.

Product Overview

The EM9304V01LF28B is a combined TxRx + MCU RF transceiver chip operating in the 2.4 GHz band that supports the Bluetooth v5.0 Low Energy (BLE) protocol. Its flexible architecture allows it to function either as a companion IC for any ASIC- or MCU-based product or as a complete system-on-chip (SoC) operating independently. By integrating the RF front-end, microcontroller, and power management system into a single compact package, it significantly reduces the number of external components, optimizes PCB space, and lowers material costs.
