MT48LC4M16A2TG-75 L:G TR

The MT48LC4M16A2TG-75 L:G TR is a 64 Mbit synchronous DRAM organized as 4M × 16 with four internal banks. It implements fully synchronous SDRAM architecture with pipelined operation and programmable burst lengths to support high-throughput parallel memory access.

Designed for systems requiring PC66/PC100/PC133-compliant synchronous DRAM operation, the device provides standard SDRAM functions including auto/precharge, auto refresh and self-refresh modes while operating from a single +3.3 V ±0.3 V supply.

Key Features

• Core & Architecture Fully synchronous SDRAM with internal pipelined operation and four internal banks for hidden row access and precharge.
• Memory Organization 64 Mbit density organized as 4M × 16 with bank addressing via BA0 and BA1.
• Timing & Performance PC66/PC100/PC133-compliant operation with 133 MHz clock capability and cycle-time options including the -75 timing (7.5 ns @ CL = 3). Specified access time 5.4 ns and write cycle time (word/page) 15 ns.
• Programmable Burst & Refresh Programmable burst lengths of 1, 2, 4, 8 or full-page plus Auto Precharge (including concurrent) and Auto Refresh. 64 ms, 4,096-cycle refresh support.
• Power & I/O Single +3.3 V ±0.3 V supply with LVTTL-compatible inputs and outputs; self-refresh modes available in standard and low-power options.
• Package & Temperature 54-pin TSOP II (0.400", 10.16 mm width) plastic package; commercial operating temperature 0°C to +70°C (TA).
• Interface Parallel SDRAM interface suitable for systems using synchronous parallel memory buses.

Typical Applications

• PC system memory (PC66/PC100/PC133) — Supports synchronous DRAM timing and burst modes for systems targeting PC66/PC100/PC133-compatible memory designs.
• Embedded systems with parallel SDRAM — 4M × 16 organization and parallel interface provide deterministic block and burst transfers for embedded designs requiring synchronous DRAM.
• Systems requiring self-refresh — Built-in self-refresh (standard and low-power) and auto-refresh support for designs that need retention during idle or low-power intervals.

Unique Advantages

• Standard SDRAM timing compatibility — PC66/PC100/PC133 compliance and -75 timing option enable straightforward integration into systems using standard SDRAM clocking and latency profiles.
• Flexible burst operation — Programmable burst lengths (1, 2, 4, 8 or full page) allow designers to optimize throughput and bus efficiency for varied access patterns.
• Robust refresh management — Auto Refresh and 4,096-cycle refresh support simplify memory retention management and reduce host overhead.
• Compact, industry-standard package — 54-pin TSOP II (400 mil) package offers a small-footprint solution for board-level integration with defined mechanical dimensions.
• Single-supply LVTTL I/O — +3.3 V supply and LVTTL-compatible inputs/outputs enable compatibility with common logic voltage domains.
• Low-power options — Self-refresh modes include low-power variants for designs that need reduced standby power.
