MT48LC2M32B2B5-6A AAT:J

The MT48LC2M32B2B5-6A AAT:J is a 64 Mbit, parallel SDRAM organized as 2M × 32 with internal 4-bank architecture. It is a fully synchronous SDR SDRAM device designed for systems that require compact, board-level DRAM storage with programmable burst modes and standard LVTTL-compatible I/O.

This device targets applications that need robust temperature performance and automotive qualification, offering a 3.0–3.6 V supply range, a 90-ball VFBGA (8 mm × 13 mm) package, and an operating temperature range from –40°C to 105°C (TA).

Key Features

• Memory Architecture — 64 Mbit organized as 2M × 32 (512K × 32 × 4 banks) providing parallel data paths for high-throughput system designs.
• SDR SDRAM Core — Fully synchronous operation with internal pipelined operation and internal banks to hide row access/precharge latency.
• Performance & Timing — Designed for a 167 MHz clock frequency (–6A speed grade) with an access time of 5.4 ns and support for CAS latencies (CL) of 1, 2, and 3.
• Programmable Burst & Refresh — Programmable burst lengths (1, 2, 4, 8, or full-page), auto precharge and auto refresh modes, and self-refresh support noted in the datasheet.
• Electrical & I/O — Single 3.3 V ±0.3 V power supply (3.0 V–3.6 V) with LVTTL-compatible inputs and outputs.
• Package & Mounting — 90-ball VFBGA (8 mm × 13 mm) package suitable for compact board layouts; supplier device package listed as 90-VFBGA (8×13).
• Temperature & Qualification — Operating temperature range –40°C to 105°C (TA) and AEC-Q100 qualification for automotive-grade applications.

Typical Applications

• Automotive systems — Suited for automotive electronics that require AEC-Q100 qualification and extended temperature operation.
• Embedded memory subsystems — Compact parallel SDRAM storage for embedded controllers and processing modules requiring deterministic synchronous memory access.
• Industrial electronics — Memory for control and monitoring equipment operating across a wide temperature range.

Unique Advantages

• Automotive-qualified robustness: AEC-Q100 qualification and –40°C to 105°C operating range enable use in temperature-stressed environments.
• Flexible performance options: Support for multiple CAS latencies and programmable burst lengths lets designers tune throughput and latency to system needs.
• Compact BGA footprint: 90-ball VFBGA (8 mm × 13 mm) minimizes PCB area while providing a full 32-bit parallel data path.
• Standard 3.3 V supply and LVTTL I/O: Simplifies power and I/O interface design with widely used voltage and signaling standards.
• Built-in refresh and power modes: Auto refresh and self-refresh (per datasheet notes) reduce external refresh management and support low-activity states.
