MT48LC16M16A2BG-7E:D TR

The MT48LC16M16A2BG-7E:D TR is a 256 Mbit parallel SDRAM device organized as 16M × 16. It is a fully synchronous SDR SDRAM device designed for systems requiring PC100/PC133-compliant parallel memory with programmable burst operation.

Typical use cases include systems that require a compact, high-frequency parallel memory solution with standard SDRAM features such as auto refresh, programmable burst lengths, and support for single 3.3 V supply operation.

Key Features

• Core / Architecture  SDR SDRAM; fully synchronous operation with all signals registered on the positive edge of the system clock and internal pipelined operation.
• Memory Organization  256 Mbit capacity organized as 16M × 16 with internal banks (4 banks as shown in datasheet tables).
• Performance  Clock frequency up to 133 MHz (PC133-compliant) with a specified access time of 5.4 ns and a write cycle time (word/page) of 14 ns.
• Burst and Access Modes  Programmable burst lengths (1, 2, 4, 8, or full page), internal banks for hiding row access/precharge, auto precharge and auto refresh modes, and self-refresh support (note: self-refresh not available on AT-marked devices per datasheet).
• Timing / Refresh  Supports 8,192-cycle refresh; datasheet lists 64 ms/8192-cycle refresh for commercial devices and timing options for PC100/PC133 speed grades.
• Power  Single-supply operation at 3.0 V to 3.6 V (datasheet reference: single 3.3 V ±0.3 V power supply).
• Package  54-ball VFBGA package, 8 mm × 14 mm (54-VFBGA, 8×14) for compact board footprint and high-density mounting.
• Operating Temperature  Commercial operating range 0°C to +70°C (TA).

Typical Applications

• PC100/PC133 memory subsystems  Use as parallel SDRAM memory in systems designed to support PC100 or PC133 timing and interface requirements.
• High-frequency buffering  Local data buffering and temporary storage in systems that require 133 MHz clock operation and low access latency.
• Compact board-level memory  Small-footprint designs that need a 54-ball VFBGA packaged parallel DRAM for space-constrained assemblies.
• Standard volatile storage  General-purpose parallel DRAM for designs that require 256 Mbit of volatile memory with programmable burst and refresh capabilities.

Unique Advantages

• PC100/PC133 compliance:  Designed to meet PC100 and PC133 timing profiles for straightforward integration into compatible memory subsystems.
• Flexible burst control:  Programmable burst lengths (1, 2, 4, 8, full page) allow tuning of throughput and latency to match system access patterns.
• High-frequency operation:  133 MHz clock support and a 5.4 ns access time provide responsive memory access for time-sensitive applications.
• Compact VFBGA package:  54-ball VFBGA (8×14) minimizes PCB area while delivering a parallel interface suitable for board-level memory expansion.
• Standard single-supply power:  Operates from a 3.0 V to 3.6 V supply (3.3 V nominal), simplifying power-rail requirements in conventional designs.
• Built-in refresh and self-refresh support:  Auto refresh and auto precharge features with self-refresh capability (per datasheet) reduce system-level refresh management overhead.
