MT48LC16M16A2P-7E IT:D TR

The MT48LC16M16A2P-7E IT:D TR is a 256 Mbit, parallel SDRAM device organized as 16M × 16 with four internal banks. It implements fully synchronous SDR SDRAM architecture and targets systems requiring PC100/PC133‑compliant parallel DRAM in a 54‑pin TSOP II package with industrial temperature range.

Key Features

• Core / Memory Organization 256 Mbit SDRAM organized as 16M × 16 with four internal banks, enabling banked row access for improved command throughput.
• Performance / Timing PC100- and PC133‑compliant operation with a 133 MHz clock frequency and an Access Time of 5.4 ns; write cycle time (word/page) of 14 ns. Speed grade -7E targets 2-2-2 timing.
• Synchronous, Pipelined Operation Fully synchronous design with signals registered on the positive clock edge and internal pipelined operation that allows column address changes every clock cycle.
• Programmable Burst & Refresh Programmable burst lengths of 1, 2, 4, 8 or full page; supports auto refresh and a 64 ms, 8192‑cycle refresh mode for commercial/industrial use. Self refresh mode is provided (not available on AT devices).
• Power Single 3.3 V power supply (3.0 V to 3.6 V specified), LVTTL‑compatible inputs and outputs.
• Package & Temperature 54‑pin TSOP II (0.400", 10.16 mm width) plastic package; specified operating temperature range of -40 °C to +85 °C (TA).

Typical Applications

• Embedded Systems Provides parallel SDRAM capacity and timing suitable for embedded controllers and memory subsystems requiring standard PC100/PC133 SDRAM.
• Industrial Equipment Industrial temperature rating (-40 °C to +85 °C) supports designs deployed in temperature‑challenging environments.
• Legacy Parallel SDRAM Designs Fits systems using parallel SDRAM interfaces and standard 54‑pin TSOP II footprints for memory expansion or replacement.
• Buffered Data Throughput Internal pipelining and multi‑bank architecture help sustain column operations and burst transfers in data‑buffering applications.

Unique Advantages

• PC100 / PC133 Compatibility: Meets PC100 and PC133 timing targets for straightforward integration into compliant platforms.
• Industrial Temperature Range: Rated from -40 °C to +85 °C (TA), enabling use in industrial assemblies where extended ambient ranges are required.
• Standard 54‑TSOP II Footprint: 0.400" (10.16 mm) width package simplifies board layout for designs using widely adopted TSOP II form factors.
• Synchronous, Pipelined Access: Fully synchronous operation with pipelining and multi‑bank architecture improves effective throughput for burst and column‑oriented transfers.
• Flexible Burst & Refresh Modes: Programmable burst lengths and auto/self refresh support simplify memory timing management and power handling strategies.
• Single 3.3 V Supply: Operates from a single 3.0 V to 3.6 V supply, matching common SDRAM power rails for system simplicity.
