MT48LC32M8A2P-7E:D TR

The MT48LC32M8A2P-7E:D TR is a 256 Mbit SDRAM organized as 32M × 8 with a parallel memory interface in a 54-pin TSOP II package. It implements fully synchronous SDRAM architecture with internal pipelined operation and internal bank management for high-efficiency row/column access.

Designed for commercial applications, the device is PC100- and PC133-compliant and operates over a 3.0 V to 3.6 V supply range with a commercial temperature rating of 0°C to 70°C, making it suitable for synchronous system memory in a variety of embedded and computing platforms.

Key Features

• Core / Memory Architecture 256 Mbit SDRAM organized as 32M × 8 with four internal banks to improve throughput and hide row access/precharge.
• Synchronous, Pipelined Operation Fully synchronous design with all signals registered on the positive edge of the system clock and internal pipelining to allow column address changes every clock cycle.
• Performance & Timing PC100- and PC133-compliant with a clock frequency up to 133 MHz; access time and timing options include the -7E speed grade (133 MHz, 2-2-2 timing) and an access time listed at 5.4 ns in product data.
• Burst & Refresh Modes Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge, auto refresh and self-refresh mode options indicated in the product documentation.
• Interface & I/O Parallel memory interface with LVTTL-compatible inputs and outputs for synchronous system integration.
• Power Single-supply operation at 3.3 V nominal (3.0 V to 3.6 V specified).
• Package & Temperature 54-pin TSOP II (0.400", 10.16 mm width) package; commercial operating temperature range 0°C to 70°C.
• Write Timing Write cycle timing includes a word/page write cycle time of 14 ns as specified in the product data.

Typical Applications

• PC100/PC133 Synchronous Systems Use as system memory in platforms requiring PC100 or PC133-compliant SDRAM.
• Embedded Commercial Electronics Integration into commercial embedded designs that require a 256 Mbit synchronous DRAM in a 54-pin TSOP II footprint.
• Legacy and Replacement Modules Ideal for designs or repairs where a 54-pin TSOP II SDRAM footprint and 32M × 8 organization are required.

Unique Advantages

• Synchronous, predictable timing: Fully synchronous operation with registered inputs on the clock edge simplifies timing analysis and integration into synchronous systems.
• Flexible burst operation: Programmable burst lengths (1, 2, 4, 8, full page) enable tuning of transfer granularity for different system throughput needs.
• Compact TSOP II package: 54-pin TSOP II (0.400", 10.16 mm) provides a compact footprint compatible with designs requiring a standardized surface-mount memory package.
• Commercial temperature rating: Specified operation from 0°C to 70°C to match commercial embedded system environments.
• Standard 3.3 V supply: Operates from 3.0 V to 3.6 V, aligning with common 3.3 V system power rails.
• Documented timing grades: Speed-grade information (–7E) and timing tables are provided in the product documentation to support system timing validation.
