MT48LC4M16A2P-6A AAT:J

The MT48LC4M16A2P-6A AAT:J is a 64 Mbit volatile SDRAM organized as 4M × 16 with a parallel memory interface. It is specified for high-frequency operation up to 167 MHz and provides transient access performance with a 5.4 ns access time and 12 ns write cycle time for word/page operations.

Designed and manufactured by Micron Technology Inc., this device targets applications that require automotive-grade qualification and extended temperature operation, offering a compact 54‑TSOP II package for board-level integration.

Key Features

• Memory Architecture 64 Mbit SDRAM organized as 4M × 16 with a parallel interface suitable for direct memory mapping and buffering tasks.
• Performance Clock frequency up to 167 MHz, typical access time of 5.4 ns and a write cycle time (word/page) of 12 ns to support responsive data access.
• Power Operates from a 3.0 V to 3.6 V supply range, allowing compatibility with systems using standard 3 V SDRAM power rails.
• Package Supplied in a 54‑TSOP II package (0.400", 10.16 mm width) for compact PCB footprint and automated surface-mount assembly.
• Environmental and Qualification Rated for an operating ambient temperature range of −40°C to 105°C and qualified to AEC‑Q100, indicating suitability for regulated automotive applications.

Typical Applications

• Automotive Systems AEC‑Q100 qualification and extended temperature range make this SDRAM suitable for electronic control units and other automotive modules requiring qualified volatile memory.
• Industrial Equipment −40°C to 105°C operating range supports industrial control and instrumentation operating in wide-temperature environments.
• Embedded Memory for Controllers Parallel SDRAM organization and 4M × 16 density provide temporary data storage and buffering for embedded processors and digital logic subsystems.

Unique Advantages

• AEC‑Q100 Qualified: Explicit automotive qualification provides a documented baseline for use in regulated vehicle electronics.
