Core acquisition categories

1, Integrated circuit (IC) : signal chain and power management full coverage ‌

Operational amplifiers/data converters such as TI's OPA2182 (precision op amp) and ADI's AD7606 (16-bit ADC) are suitable for industrial sensors and medical devices.

Power Management chips (PMIC) ‌ : includes Infineon's TLE946x series (multi-output vehicle rating PMIC), supporting extreme environments from -40 ° C to +150 ° C.

2. Microcontroller (MCU) : double upgrade of computing power and energy efficiency ‌

Industrial MCU‌ : ST STM32H7 series (dual-core Cortex-M7/M4, main frequency 480MHz), enabling machine vision and real-time control.

Low-power iot MCU‌ : Renesas RA4M3 series (dynamic power down to 100μA/MHz) for smart meters and wearable devices.

3‌, automotive chip: electric and intelligent core devices ‌

In-vehicle control chips ‌ : NXP S32K series (ASIL-D MCU) for BMS and motor drives.

‌ Sensor and communication chip ‌ : Bosch BME688 (vehicle scale gas sensor), Renesas RH850/V2H (Vehicle Ethernet gateway chip).

‌

4. Internet of Things chip: dual engine of connection and edge intelligence ‌

Wireless communication modules ‌ : Nordic nRF9160 (LTE-M/NB-IoT+GNSS), Silicon Labs BG24 (Bluetooth 5.3+Zigbee).

AIoT fusion chip ‌ : Renesas RA8 series (integrated NPU, 2.3TOPS) for localized speech recognition and predictive maintenance.

Acquisition process

Quick evaluation ‌ : provide chip model, package, quantity and batch information, feedback within 24 hours ‌;

Compliance delivery ‌ : only accept formal channels of goods (agents/traders inventory), to ensure the legality and traceability of the transaction ‌;

Fund settlement ‌ : support cash payment, covering factory delisted materials, production line redundant inventory and other scenarios ‌.

Through large-scale chip inventory acquisition and refined operations, Shenzhen Mingjiada Electronics not only builds a supply chain "safety mat" for global customers, but also promotes the efficient transfer of semiconductor industry resources with an innovative model. In the context of stock-out normalization and low-carbon transformation, this strategy may become a key paradigm for the electronics manufacturing industry to deal with uncertainty.
