MT48LC4M16A2TG-75 IT:G TR

The MT48LC4M16A2TG-75 IT:G TR is a 64 Mbit synchronous DRAM device configured as 4M x 16 with 4 internal banks. It implements a fully synchronous, parallel SDRAM architecture with support for programmable burst lengths, internal pipelined operation, and standard auto-refresh/self-refresh modes.

This industrial-temperature SDRAM is targeted at systems requiring a compact 54‑pin TSOP II package, 3.3 V operation, and PC‑class SDRAM timing (PC66/PC100/PC133 compatibility). It is suited for embedded and industrial designs that need a parallel SDRAM memory interface with hardware-managed refresh and low-power options.

Key Features

• Core / Memory Organization 64 Mbit SDRAM organized as 4M x 16 with 4 internal banks, providing standard SDRAM row/column bank architecture for pipelined operation.
• Performance PC66-, PC100-, and PC133-compliant timing with a 133 MHz clock frequency and an access time of 5.4 ns; supports programmable burst lengths (1, 2, 4, 8, or full page).
• System Features Fully synchronous operation with all signals registered on the positive clock edge, internal pipelined operation, internal banks to hide row access/precharge, Auto Precharge (including concurrent Auto Precharge) and Auto Refresh modes.
• Power and Refresh Single +3.3 V supply (3.0 V to 3.6 V) with standard and low-power self-refresh modes; 64 ms, 4,096-cycle refresh supported for data retention.
• Interface and I/Os Parallel memory interface with LVTTL-compatible inputs and outputs; write-cycle time (word/page) specified at 15 ns.
• Package and Temperature 54‑pin TSOP II package (0.400", 10.16 mm width) and industrial operating temperature range of −40 °C to +85 °C.

Typical Applications

• PC and legacy systems Supports PC66/PC100/PC133 timing for integration into platforms that require standard SDRAM timing compatibility.
• Industrial embedded equipment Industrial temperature range (−40 °C to +85 °C) and 3.3 V supply make it suitable for embedded controllers and instrumentation operating in harsh environments.
• Compact memory modules 54‑pin TSOP II package enables space-constrained board-level memory implementations where a 64 Mbit SDRAM is required.

Unique Advantages

• Standard SDRAM timing compliance: PC66/PC100/PC133 compatibility simplifies integration with systems designed for these timing classes.
• Industrial temperature rating: Operates from −40 °C to +85 °C, allowing deployment in temperature-challenging environments.
• Single 3.3 V supply: 3.0 V–3.6 V supply range aligns with common system rails for simplified power design.
• Compact TSOP II package: 54‑pin 0.400" TSOP II footprint supports high-density board layouts.
• Power-management modes: Standard and low-power self-refresh options reduce power during idle periods and maintain data integrity.
• Hardware-managed refresh and pipelining: Internal banks, auto-refresh, and pipelined operation reduce controller complexity and improve effective throughput.
