Shenzhen Mingjiada Electronics Co., LTD., as a globally leading electronic component recycler, has long been dedicated to the recycling business of microcontroller (MCU) chips, especially providing professional and high-price recycling services for the (Renesas) RL78 series low-power 8-bit / 16-bit microcontrollers. With a mature evaluation system and a global network, Mingjiada provides efficient and compliant inventory liquidation solutions for customers in the industrial chain, helping manufacturing enterprises, traders and end factories optimize their supply chains and accelerate capital recovery.

I. RL78 Series MCU: A core technical pillar in the low-power market

The RL78 series is Renesas' flagship low-power MCU product line, featuring both high performance and ultra-low energy consumption, and is widely applied in automotive electronics, industrial control, and consumer electronics fields. Its core advantages include:

Ultimate energy efficiency design

The operating power consumption is as low as 37.5μA/MHz (RL78/G22), and the power consumption in standby mode (STOP) is only 200nA, supporting battery-powered devices to work continuously for several years.

The working voltage range is as wide as 1.6V to 5.5V, which can fully drain the remaining battery power and significantly extend the lifespan of terminal products.

Diversified sub-series meet segmented demands

RL78/F24: Automotive-grade MCU, supporting ISO 26262 ASIL-B functional safety standard and CAN FD interface, resistant to high temperature up to 150°C, specially designed for intelligent actuators and sensors;

RL78/G15: The industry's smallest package (3×3mm 8-pin), suitable for space-constrained scenarios such as compact motor control and lighting systems;

RL78/G22: Integrated capacitive touch channel (CTSU2L), supporting up to 32 touch keys, designed for home appliances and HMI interfaces.

Ii. Why Recycle the RL78 Series?

Drivers of recycling value

Strong terminal demand: The RL78 series has cumulatively shipped over 7.1 billion units, with a monthly shipment volume of 100 million units. It is widely embedded in automotive BCM (Body Control Module), variable frequency motors, and Internet of Things devices, forming a huge second-hand circulation market.

Supply chain fluctuation response: In recent years, the shortage of chips has prompted enterprises to hoard inventories. Models such as RL78/F24, which comply with automotive-grade certifications (ISO 26262), have become high-risk categories for redundant inventory.

Environmental compliance pressure: The control of electronic waste is becoming stricter, and professional recycling can avoid the risk of illegal disposal.

Three and four-step efficient recycling processes

List submission: The customer provides the RL78 model (such as RL78/G14, RL78/F15), quantity, batch and packaging information;

1-hour quotation: Professional team assesses based on real-time market data and quickly provides high-price solutions.

Global logistics inspection: Supports door-to-door pickup or DHL/UPS international logistics to complete authenticity detection and quality grading.

24-hour settlement: Cash payment (USD/RMB supported) will be made within 24 hours after inspection. The maximum recycling value of a single batch can reach 60-80% of the new material price.

Iv. Service Advantages of Mingjiada: Dual Engines of Professionalization and Globalization

Mingjiada has been deeply engaged in electronic recycling for nearly 30 years and has built a unique competitive edge in the RL78 series recycling field

Precise assessment capability: The technical team is proficient in the Renesas product line and can identify the value of rare models such as RL78/F13/F14/F15 compatible models and automotive-grade RL78/F24.

Compliance traceability system: Only accepts regular sources from agents, factories and traders, and strictly prohibits counterfeit and illegal disassembled products.

Global service network: Set up points in Japan, the United States, Germany, Hong Kong and other places, supporting integrated processing of cross-border inventory;

Flexible trading model: We offer three solutions - consignment sales, consignment sales, and clearance sales - to meet the cash flow needs of our clients.
