Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the revolutionary wave of software-defined vehicles (SDVS) and central computing architectures, automotive-grade functional safety has become the core lifeline of intelligent mobility. Renesas' RH850 series 32-bit MCU, with its ASIL-D lock-step core, gigabit-level real-time communication and a ten-year long life cycle, has become the "safety brain" for over 100 million vehicles worldwide. However, the inventory redundancy and the upgrade of electronic and electrical architectures following the chip shortage are turning a large number of brand-new original RH850 MCUS into "frozen assets", facing an average annual value depreciation of 25%. Shenzhen Mingjiada Electronics Co., LTD., relying on its ten years of expertise in automotive-grade chip recycling, has specially launched a high-price recycling service for the entire RH850 series of MCUS. With military-grade testing, dynamic premium models, and 72-hour global payment collection, it helps Tier 1 and Oems revitalize their inventories worth tens of millions and reconstruct the green and circular ecosystem of automotive electronics.

I. RH850 Technology Benchmark: Defining the Safety Boundary of Automotive Electronics

The ultimate fortress of functional safety

Lock-step dual-core architecture: Cortex-R52 dual-core redundant execution + 300MHz main frequency, fault detection coverage >99.99% (such as RH850/P1x-C), meeting the ASIL-D requirements of the steering/braking system;

Comprehensive security protection: ECC memory + voltage and frequency monitoring + built-in self-check (LBIST), single-point failure rate <10 FIT;

Cyber attack immunity: The Hardware Security Module (HSM) supports the EVITA Full standard, with an encryption performance of up to 5000 signatures per second.

2. Gigabit-level real-time communication capability

In-vehicle Ethernet hub: Integrated TSN switch + 4 channels of 1000BASE-T1 PHY (such as RH850/U2x), achieving μ S-level data synchronization between ADAS domain and cockpit domain;

Multi-domain control bridge: Dual-channel CAN FD + FlexRay + LIN, supporting OTA over-the-air upgrade of gateway firmware.

3. Exclusive optimization for new energy

High-voltage system control: RH850/E2x supports 800V battery management, and a 24-bit high-precision ADC achieves a 0.01% SOC accuracy.

SiC drive integration: Built-in dead zone control and desaturation detection (DESAT), directly driving 1200V silicon carbide modules.

Mingjiada high-price purchase of key models

The premium rate of the intelligent driving safety flagship: RH850/P1H-C (ASIL-D) has reached 35% due to the sharp increase in the penetration rate of the L3+ system.

Domain controller core: RH850/U2A8 (Gigabit Ethernet) with a 30% premium;

The three-electricity system solution: RH850/E2M (800V BMS) has a 25% premium due to the urgent need for maintenance and repair in the new energy sector.

Ii. Mingjiada Recycling System: A "Zero-risk" Closed Loop for Automotive-grade Chips

1. ASIL-D level detection process

Wafer traceability verification: X-ray comparison with Renesas wafer batch codes, and lid open analysis (Decap) verification for 40nm process nodes.

Extreme environment test: The temperature box operates the lockstep self-check program at -55℃ to 175℃, and the fault injection response qualification rate is 100%.

Communication stress test: Dedicated carrier board verifies the stability of CAN FD 8Mbps/CAN XL 20Mbps, with a frame error rate of less than 1E-9.

2. Data security clearance mechanism

HSM key burnout: Physical melting of efuse storage area, certified by ISO 21434;

Firmware deep erase: Perform 32 overwrite writes to Flash, meeting the NIST SP 800-88 Rev.1 standard.

3. Dynamic Supply and Demand pricing model

Based on the global automotive aftermarket database:

The U2x series supporting Ethernet TSN is in short supply for intelligent driving, with a 40% premium.

Packaging status bonus: For unremoved pallet materials (original factory vacuum + nitrogen filling), the price is increased by 8%.

Batch stepped reward: If the single recycling exceeds 3,000 pieces, the unit price will increase by another 5%.

Three and four-step rapid monetization: Global funds arrive within 5 days

Encrypted list submission: model (e.g. RH850/P1H-CMA)/quantity/package photo to sales@hkmjd.com, pre-price within 20 minutes;

High-definition video verification: 48-hour remote inspection of Renesas laser codes and BGA solder balls;

Safe delivery: Optional delivery at Shenzhen/Stuttgart/Nagoya inspection centers, or FedEx tamper-proof armored boxes for global cash on delivery.

Payment upon inspection: Full payment will be made by telegraphic transfer within 24 hours of arrival. Settlement is supported in US dollars/euros.

Iv. Industry Practice: The Value Rebirth of Security Assets

Tier 1 of a certain braking system: Dispose of the backlog of P1H-C chips (8,000 pieces), activate 32 million yuan of funds, and invest in the research and development of by-wire braking.

New energy vehicle manufacturers: Recover E2M inventory (12,000 pieces), reducing warehousing costs by 1.8 million yuan per year;

Intelligent gateway supplier: Converted discontinued models (such as RH850/F1x) into cash flow, avoiding depreciation losses of over 15 million yuan.

Conclusion: Reshaping the automotive chip ecosystem through strategic recycling

Mingjiada Electronics builds a "golden outlet" for high-value MCU inventories for automakers by integrating automotive-grade testing capabilities, a global maintenance network, and zero-risk data clearance.

Unleash the value of your safe assets immediately!
