🔑 Key Specifications & Features
Device Type: LPDDR5 SDRAM (Low Power DDR5) – Automotive Grade
Density: 64Gb (Gigabits) / 8GB (Gigabytes)
Organization: 2Gb x32
The "2G32" indicates a memory depth of 2 Gigabits with a 32-bit data bus width.
Note: This density typically utilizes Micron's advanced 16Gb die technology (4 internal dies of 2Gb each).
Speed / Data Rate: The suffix "026" indicates a data rate of 6400 MT/s (Megatransfers per second).
Note: This is a standard high-performance speed bin for LPDDR5, offering significantly faster bandwidth than LPDDR4X memory.
Temperature Range: Full Automotive temperature range (typically -40°C to +105°C).
Note: The "AAT" designation indicates full AEC-Q100 Grade 1 qualification, ensuring stability in the harshest automotive environments.
Compliance:
AEC-Q100 Grade 1: Fully compliant with the most stringent automotive stress test requirements.
JEDEC Standard: Compliant with industry-standard LPDDR5 specifications.
Package: FBGA (Fine Pitch Ball Grid Array)
The "DS" package code indicates a specific package type (likely 315-ball) designed to accommodate the internal stacking required for this density while maintaining the x32 interface.
Key Technologies:
On-die ECC: Internal error correction, crucial for maintaining data integrity and functional safety (ISO 26262) in high-density chips.
DFE (Decision Feedback Equalization): Ensures signal integrity at high data rates (6400 MT/s).
Self-Refresh Modes: Optimized for low power consumption to support vehicle battery efficiency.
💡 Typical Applications
Autonomous Driving Systems: High-performance computing platforms processing LIDAR and radar data.
ADAS (Advanced Driver Assistance Systems): Safety-critical modules requiring zero-failure operation.
Digital Cockpits: Advanced instrument clusters combining multiple displays and AI assistants.
Automotive Infotainment: High-end navigation and entertainment systems requiring large memory capacity.
Note: The "AAT:B" refers to the Automotive Trace or Revision code (Revision B). This identifies the specific manufacturing lot or silicon revision qualified for full automotive use, which is critical for traceability and safety compliance in automotive supply chains.
