MT48LC4M16A2B4-6A:J

The MT48LC4M16A2B4-6A:J is a 64 Mbit synchronous DRAM (SDRAM) device organized as 4M × 16 with a parallel memory interface. It is a volatile memory component offered in a 54-ball VFBGA (8 mm × 8 mm) package and operates from a 3.0 V to 3.6 V supply.

Designed for systems that use SDR SDRAM, this device supports high-speed synchronous operation at a 167 MHz clock frequency (–6A speed grade) and provides standard SDRAM features such as programmable burst lengths, auto precharge and auto refresh modes.

Key Features

• Memory Architecture — 64 Mbit capacity organized as 4M × 16 with internal bank architecture for concurrent row access and precharge.
• SDR SDRAM Technology — Fully synchronous operation with signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes every clock cycle.
• Performance — 167 MHz clock frequency (–6A speed grade); timing table lists 3-3-3 RCD-RP-CL targets at this grade.
• Access and Cycle Timing — Access time specified in product data; write cycle time (word/page) of 12 ns supports burst transfers.
• Refresh and Self-Refresh — Auto refresh support with 4K refresh cycles and both standard and low-power self-refresh modes (low-power option noted in datasheet options).
• Voltage and I/O — Single-supply operation at 3.3 V nominal (3.0 V to 3.6 V range) with LVTTL-compatible inputs and outputs as described in the datasheet.
• Package and Temperature — 54-ball VFBGA (8×8 mm) package; commercial operating temperature range of 0°C to +70°C (TA).
• SDR Compliance and Options — Datasheet lists PC100- and PC133-compliant options and programmable burst lengths of 1, 2, 4, 8 or full page.

Typical Applications

• PC100/PC133 memory subsystems — Suitable for systems targeting PC100/PC133-compliant SDRAM implementations at the listed speed grades.
• Parallel-memory embedded designs — Used where a parallel SDRAM interface and 3.3 V supply are required.
• Board-level DRAM expansion — Compact VFBGA package provides a small-footprint option for adding SDRAM capacity on circuit boards.

Unique Advantages

• Proven SDRAM architecture: Fully synchronous, pipelined operation with internal banks for predictable burst and column behavior.
• Speed-grade clarity: –6A speed grade with 167 MHz clock frequency and 3-3-3 timing targets documented in the datasheet for design planning.
• Compact package: 54-ball VFBGA (8×8 mm) package minimizes PCB area while providing a parallel memory interface.
• Single-supply operation: 3.0 V to 3.6 V supply range (3.3 V nominal) aligns with common system power rails.
• Refresh and low-power options: Supports 4K refresh cycles and offers self-refresh modes described in the datasheet for power management.
• Commercial temperature rating: Rated for 0°C to +70°C operational environments.
