According to IDC data, the global penetration rate of smart vehicles will exceed 50% in 2025, and the storage demand per smart vehicle will reach 3–5 times that of consumer electronic devices. As an optimal solution balancing cost and performance, automotive-grade eMMC is experiencing an explosive surge in demand.
When we talk about smart vehicles, our attention is always drawn to the precision of autonomous driving, the smoothness of central control screens, and the convenience of vehicle connectivity. Yet few notice the unsung hero quietly powering these experiences: Automotive-Grade Embedded Multi-Media Card (eMMC). As a core storage component in automotive electronic systems, it not only stores critical data such as navigation maps, in-vehicle system firmware, and driver assistance algorithms but also maintains stability in extreme environments—truly acting as the data security guardian of smart vehicles. Today, let us comprehensively dissect the core value of the China Chips Star PG Brand Automotive-Grade eMMC, from technical details to practical applications.
Core Advantages of PG Brand Automotive-Grade eMMC
1. Extreme Environment Resistance
Vehicles operate across a wide range of scenarios, from the frigid polar regions to scorching desert areas, and even endure extreme conditions such as interior overheating under summer sunlight and outdoor freezing in winter.
PG Brand Automotive-Grade eMMC has obtained AEC-Q100 automotive component reliability certification, with an operating temperature range of -40°C to 85°C; certain high-spec models can withstand temperatures from -45°C to 105°C. It maintains stable read/write performance amid drastic temperature fluctuations, preventing data loss caused by low-temperature lag or high-temperature power failure.
Additionally, it has passed the ISO 16750-3 mechanical vibration test, capable of withstanding shocks from engine vibrations and road bumps during vehicle operation (vibration frequency range: 10Hz–2000Hz).
2. Long Service Life & High Reliability
PG Brand Automotive-Grade eMMC supports over 3,000 Program/Erase (P/E) Cycles, balancing storage capacity and lifespan. It is ideal for storing large-volume data like navigation maps and multimedia files, as well as high-frequency read/write data such as in-vehicle system firmware and ADAS core algorithms.
Equipped with a hardware-level Wear Leveling algorithm, it evenly distributes the erasure/write stress across storage cells, preventing premature damage to local cells and ensuring zero storage failures over an extended service period.
3. Advanced Security Protection
Stored data in smart vehicles is not only critical to user experience but also closely linked to driving safety. For example, tampering with ADAS system algorithm data may lead to misjudgments in driver assistance functions; intrusion into in-vehicle system firmware could cause vehicle malfunctions.
To address these risks, PG Brand Automotive-Grade eMMC has built a multi-layered security defense system:
- Hardware Encryption: Integrated with an AES-256 encryption module, it provides real-time encryption for sensitive stored data (e.g., user privacy information, vehicle control programs). Even if the chip is physically disassembled, the data remains unbreakable.
- Secure Boot: Supports bottom-up verification of system firmware integrity. Only firmware authenticated by digital signatures can be booted, preventing malicious program injection.
- Electromagnetic Compatibility (EMC): Passed the ISO 11452-2 electromagnetic radiation immunity test, it resists strong electromagnetic interference from components such as engines, motors, and on-board radars, avoiding data transmission errors and packet loss.
Indispensable Component for 4 Core In-Vehicle Systems
1. In-Vehicle Infotainment (IVI) System
Functions such as central control displays, navigation, music, and video playback rely on stable storage support. PG Brand Automotive-Grade eMMC stores navigation map data, multimedia files, and system firmware, ensuring smooth operation of the central control system—free from lag or crashes—even during vehicle vibrations and temperature changes.
2. Advanced Driver Assistance System (ADAS)
ADAS (e.g., adaptive cruise control, lane departure warning, automatic emergency braking) requires real-time collection of data from cameras, radars, and other sensors, as well as rapid retrieval of preloaded algorithm models.
With its high-speed read/write capability (up to 330MB/s read speed) and superior reliability, PG Brand Automotive-Grade eMMC guarantees timely and accurate data transmission, providing stable support for driver assistance decision-making.
3. Body Control Module (BCM)
Control programs for body functions such as window lifting, lighting control, and air conditioning adjustment are also stored in automotive-grade eMMC. PG Brand Automotive-Grade eMMC maintains stable performance in the complex electrical environment of vehicles, preventing body function failures caused by storage malfunctions and safeguarding the safety of basic vehicle operations.
4. Battery Management System (BMS) for New Energy Vehicles
For new energy vehicles, the BMS serves as the "brain of the battery", responsible for monitoring battery parameters such as voltage, temperature, and state of charge to prevent overcharging and over-discharging.
PG Brand Automotive-Grade eMMC stores critical information including battery historical data and charge-discharge curves, providing data support for battery health management and safety protection, and extending battery service life.
In the era of rapid smart vehicle development, though compact in size, the China Chips Star PG Brand Automotive-Grade eMMC undertakes the crucial mission of ensuring vehicle safety and system stability. It is more than just a storage medium—it is the first line of defense for smart vehicle data security.
With continuous technological upgrades, PG Brand Automotive-Grade eMMC will evolve toward higher speed, larger capacity, and enhanced security levels, continuing to safeguard the advancement of smart vehicles.
