MT48LC4M32B2B5-6A AIT:L TR

The MT48LC4M32B2B5-6A AIT:L TR is a 128 Mbit synchronous DRAM organized as 4M x 32 with a parallel memory interface. It provides synchronous, pipelined SDRAM functionality with programmable burst lengths and CAS latency options for systems that require predictable, high-throughput volatile storage.

This device targets applications that need a compact, automotive-grade memory solution with a 90-ball VFBGA package, AEC-Q100 qualification, and an extended operating temperature range of -40°C to 85°C.

Key Features

• Core & memory architecture  128 Mbit organized as 4M x 32 with four internal banks for efficient row access and hidden precharge.
• Synchronous SDRAM operation  Fully synchronous design with all signals registered on the positive clock edge and internal pipelined operation for column-address changes every clock cycle.
• Performance & timing  Up to 167 MHz clock frequency with an access time around 5.4–5.5 ns and write cycle time (word page) of 12 ns; supports CAS latencies 1, 2, and 3.
• Burst and refresh modes  Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge (including concurrent auto precharge), auto refresh, and self refresh modes.
• Voltage & I/O  Single-supply operation from 3.0 V to 3.6 V with LVTTL-compatible inputs and outputs for standard parallel interfacing.
• Reliability & qualification  AEC-Q100 qualified and specified for an operating ambient temperature range of -40°C to 85°C.
• Package  Compact 90-ball VFBGA package (8 mm × 13 mm) optimized for space-constrained system designs.

Typical Applications

• Automotive electronic control units (ECUs)  Automotive-grade qualification and extended temperature rating make it suitable for memory buffers and working storage in vehicle systems.
• Industrial control and instrumentation  Extended operating temperature and reliable refresh modes support deterministic storage needs in industrial environments.
• Embedded systems with parallel SDRAM interfaces  Use as system DRAM for embedded controllers, buffering, and data staging where parallel access and programmable burst behavior are required.

Unique Advantages

• Automotive-grade qualification: AEC-Q100 qualification provides documented device-level qualification for automotive applications.
• Predictable synchronous performance: Fully synchronous operation with pipelined access and selectable CAS latencies supports predictable timing for system designers.
• Flexible burst configuration: Programmable burst lengths and auto precharge/auto refresh modes simplify memory control for variable throughput needs.
• Compact form factor: 90-ball VFBGA (8×13 mm) package minimizes PCB area while delivering 128 Mbit density.
• Standard 3.3 V supply: Single +3.3 V ±0.3 V supply simplifies power domain design and integration with common system voltages.
