MT48LC4M16A2B4-7E:J TR

The MT48LC4M16A2B4-7E:J TR is a 64 Mbit volatile SDRAM organized as 4M × 16 with a parallel memory interface. It implements synchronous SDRAM architecture with internal pipelined operation and banked memory for efficient row/column access.

Targeted at designs that require a compact, parallel SDRAM device, this part offers PC100/PC133-compliant operation, a 133 MHz clock capability, and a 54-ball VFBGA (8 × 8 mm) package for board-level memory integration.

Key Features

• Memory Architecture 64 Mbit SDRAM organized as 4M × 16 with internal banks to optimize row access and precharge sequencing.
• SDR SDRAM Core Fully synchronous operation with all signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes every clock cycle.
• Performance 133 MHz clock frequency with an access time of 5.4 ns and a word page write cycle time of 14 ns for timing-sensitive designs.
• Timing Options PC100- and PC133-compliant timing; datasheet lists programmable CAS/read latency and burst lengths (BL = 1, 2, 4, 8, or full page).
• Refresh and Power Modes Auto refresh and self refresh modes are supported (standard and low-power modes noted in the datasheet; low-power not available on AT devices).
• Interface and I/O Parallel memory interface with LVTTL-compatible inputs and outputs for system-level signaling compatibility.
• Power Single-supply operation from 3.0 V to 3.6 V (3.3 V ±0.3 V as specified in the datasheet).
• Package and Temperature 54-ball VFBGA (8 × 8 mm) package; commercial operating temperature range of 0°C to +70°C (TA).

Typical Applications

• Parallel Memory Systems — Fits board-level designs that require a compact, parallel SDRAM device with 64 Mbit capacity and PC100/PC133 timing.
• Embedded Boards — Provides synchronous DRAM storage for embedded systems needing a 4M × 16 memory organization in a small VFBGA footprint.
• Timing-Critical Designs — Suited for applications that require defined access time and write cycle timing (5.4 ns access time, 14 ns word-page write cycle).

Unique Advantages

• Compact VFBGA Package: 54-ball VFBGA (8 × 8 mm) minimizes PCB area for space-constrained designs.
• Industry Timing Compliance: PC100 and PC133 timing compatibility simplifies integration with systems designed to those clock standards.
• Flexible Burst and Bank Management: Programmable burst lengths and internal banks enable efficient data transfer patterns and hidden row access.
• Standard Voltage Range: Operates from 3.0 V to 3.6 V, matching common 3.3 V system rails for straightforward power integration.
• Deterministic Performance: Documented access time (5.4 ns) and write-cycle timing (14 ns) support predictable memory timing analysis.
