MT48LC16M8A2P-7E:L

The MT48LC16M8A2P-7E:L is a 128 Mbit synchronous DRAM device organized as 16M × 8 with a parallel memory interface in a 54-pin TSOP II (0.400", 10.16 mm width) package. It implements SDR SDRAM architecture with internal pipelined operation, internal banks, and programmable burst lengths for synchronous data transfers.

Designed for PC100/PC133-compliant systems, the device targets applications requiring a 3.3 V single-supply SDRAM solution with a 133 MHz clock frequency and commercial operating range (0 °C to +70 °C).

Key Features

• Memory Architecture 128 Mbit density organized as 16M × 8 with four internal banks to support concurrent row access and precharge hiding.
• SDR SDRAM Performance PC100- and PC133-compliant SDR SDRAM. Specified clock frequency of 133 MHz and timing grade -7E supporting 2-2-2 CAS latency (CL = 15 ns) per the datasheet.
• Flexible Burst and Refresh Programmable burst lengths (1, 2, 4, 8, or full page), auto-precharge, and auto-refresh (64 ms, 4096-cycle refresh for commercial/industrial options detailed in the datasheet).
• Interface and Timing Fully synchronous operation with all signals registered on the positive clock edge; internal pipelined operation allows column-address changes every clock cycle.
• Power Single-supply operation with VCC = 3.3 V ±0.3 V (specified voltage range 3.0 V to 3.6 V).
• Package and Mounting 54-pin TSOP II package (0.400" / 10.16 mm width) intended for surface mounting in space-constrained board designs.
• Operating Conditions Commercial operating temperature range of 0 °C to +70 °C and write cycle time (word page) of 14 ns as listed in product specifications.

Typical Applications

• PC100/PC133 Memory Subsystems Use in systems targeting PC100/PC133-compliant SDRAM configurations where synchronous parallel DRAM is required.
• Embedded Systems with Parallel SDRAM Board-level memory and buffering for embedded designs that require a 128 Mbit parallel SDRAM device in a TSOP II package.
• High-Throughput Data Buffers Applications needing pipelined SDRAM operation and programmable burst lengths for sustained data transfer bursts.

Unique Advantages

• Standards Compatibility: PC100 and PC133 compliance ensures the device aligns with established SDR SDRAM timing profiles referenced in the datasheet.
• Synchronous, Pipelined Operation: Positive-edge clocked signaling and internal pipelining permit column address updates every clock cycle for predictable synchronous behavior.
• Single 3.3 V Supply: Operates from a single 3.0 V to 3.6 V supply, simplifying power rail design and integration into 3.3 V systems.
• Compact TSOP II Package: 54-pin TSOP II (0.400") footprint enables surface-mount deployment in space-constrained boards.
• Advanced Memory Controls: Auto precharge, auto refresh, and selectable burst lengths reduce host controller complexity for common SDRAM operations.
• Commercial Temperature Range: Specified for 0 °C to +70 °C operation to match standard commercial system environments.
