📝 Product Description
Micron 64Gb Automotive LPDDR5 SDRAM
This component is a 64 Gigabit (8GB) LPDDR5 DRAM chip. It is designed for automotive systems that demand high bandwidth and reliability in extreme temperatures. It features a x32 interface and operates at a high-performance speed of 7500 MT/s, making it suitable for advanced infotainment, ADAS, and digital cockpit applications.
🔑 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 "023" indicates a data rate of 7500 MT/s (Megatransfers per second).
Note: This is a high-performance speed bin, offering significantly faster bandwidth than standard LPDDR4X memory.
Temperature Range: Automotive temperature range (typically -40°C to +105°C).
Note: The "AIT" designation ensures stable operation in harsh automotive environments, bridging the gap between standard industrial and full automotive Grade 1 requirements.
Compliance:
AEC-Q100: Compliant with 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 in high-density chips.
DFE (Decision Feedback Equalization): Ensures signal integrity at high data rates (7500 MT/s).
Self-Refresh Modes: Optimized for low power consumption to support vehicle battery efficiency.
💡 Typical Applications
Automotive Infotainment: High-end navigation and entertainment systems requiring large memory capacity.
Digital Cockpits: Advanced instrument clusters and head-up displays.
ADAS (Advanced Driver Assistance Systems): Systems processing data from cameras and sensors.
Telematics: Connected car modules requiring high-speed data processing.
Note: The "AIT:B" refers to the Automotive Industrial Trace or Revision code (Revision B). This identifies the specific manufacturing lot or silicon revision qualified for automotive use, which is critical for traceability and quality control in automotive supply chains.
