MT48LC4M16A2TG-6:G

The MT48LC4M16A2TG-6:G is a 64 Mbit synchronous DRAM (SDRAM) organized as 4M × 16 with a parallel memory interface in a 54-pin TSOP II (0.400", 10.16 mm width) package. It operates from a single 3.3 V supply range and is specified for commercial ambient temperatures (0 °C to +70 °C).

Designed for systems that require synchronous, pipelined DRAM operation, it supports programmable burst lengths, internal bank management and standard/self refresh modes. Note: the datasheet includes a notation that this device is not recommended for new designs.

Key Features

• Core & Architecture Fully synchronous SDRAM with internal pipelined operation and internal banks for hiding row access/precharge, enabling column address changes every clock cycle.
• Memory Organization 64 Mbit capacity configured as 4M × 16 with four internal banks.
• Performance & Timing Supports up to 167 MHz clock frequency with an access time of 5.5 ns and a write cycle time (word/page) of 12 ns; programmable CAS and burst operation.
• Refresh & Power Modes Auto Refresh and Auto Precharge modes, plus standard and low-power Self Refresh; 64 ms / 4,096-cycle refresh supported.
• Voltage & I/O Single supply operation at 3.3 V nominal (3.0 V to 3.6 V range) with LVTTL-compatible inputs and outputs.
• Package & Temperature 54-pin TSOP II (400 mil) plastic package, 10.16 mm width; commercial operating temperature range 0 °C to +70 °C.
• Standards Compatibility Documented PC66-, PC100- and PC133-compliant timing options in the datasheet.

Typical Applications

• PC memory subsystems — Suitable for designs that require PC66/PC100/PC133-compliant synchronous DRAM timing.
• Embedded and commercial systems — Works in systems running from a 3.3 V supply with a commercial 0 °C to +70 °C ambient range where parallel SDRAM is specified.
• Parallel SDRAM modules and buffers — Used where a compact 54-pin TSOP II package and a 4M × 16 organization are appropriate for board-level memory implementations.

Unique Advantages

• Synchronous pipelined operation: Enables column address changes every clock cycle for predictable, clocked memory behavior.
• Flexible burst control: Programmable burst lengths (1, 2, 4, 8 or full page) to match different data-transfer patterns.
• Integrated refresh management: Auto Refresh and Self Refresh modes reduce external refresh handling and support low-power retention modes.
• Single-supply LVTTL I/O: Operates from a single +3.3 V supply with LVTTL-compatible inputs/outputs for straightforward interfacing.
• Compact board footprint: 54-pin TSOP II (400 mil) package provides a small profile for space-constrained designs.
• Vendor-specified timing options: Datasheet lists PC66/PC100/PC133 timing variants to support established synchronous memory timing families.

Why Choose MT48LC4M16A2TG-6:G?

The MT48LC4M16A2TG-6:G offers a documented SDRAM solution with a 4M × 16 organization, supported timing variants and standard refresh/power modes, packaged in a compact 54-pin TSOP II. Its single 3.3 V supply, LVTTL I/O compatibility and commercial temperature rating make it suitable for existing designs and modules that require synchronous parallel DRAM behavior.

Because the datasheet specifies compliance with PC66/PC100/PC133 timing options and provides detailed timing and refresh characteristics, this device is well suited for engineers maintaining or supporting systems that rely on these synchronous DRAM conventions.
