MT48LC16M16A2P-75:D TR

The MT48LC16M16A2P-75:D TR is a 256 Mbit SDR SDRAM organized as 16M × 16 with four internal banks and a parallel memory interface. It is supplied in a 54-pin TSOP II (400 mil / 10.16 mm) package and targets designs requiring synchronous DRAM with programmable burst operation and standard refresh modes.

Key attributes include PC100/PC133 compliance, fully synchronous registered signaling, a 133 MHz clock frequency, and a commercial operating temperature range of 0 °C to 70 °C. The device operates from a single 3.3 V ±0.3 V supply and supports a range of internal timing and power-management features for system integration.

Key Features

• Memory Organization  The device is a 256 Mbit SDRAM configured as 16M × 16 with four internal banks, providing parallel data access suited to bus-based memory systems.
• Performance & Timing  PC100- and PC133-compliant with a clock frequency of 133 MHz and an access time of 5.4 ns; timing targets for the -75 speed grade include 3-3-3 RCD-RP-CL (CL = 20 ns).
• Operation & Modes  Fully synchronous operation with all signals registered on the positive clock edge; internal pipelined architecture allows column address changes every clock cycle. Supports programmable burst lengths of 1, 2, 4, 8, or full page, auto precharge, auto refresh and self-refresh modes.
• Refresh  Implements standard refresh sequences with 8K refresh cycles; commercial devices use a 64 ms, 8192-cycle refresh interval.
• Power  Single 3.3 V ±0.3 V supply (listed as 3.0 V to 3.6 V) with LVTTL-compatible inputs and outputs.
• Package & Temperature  Available in a 54-pin TSOP II (0.400", 10.16 mm width) plastic package; specified commercial operating temperature range 0 °C to +70 °C.
• Write & Cycle Timing  Write cycle time for word/page operations is specified at 15 ns for supported modes.

Unique Advantages

• Standard SDRAM compatibility: Conforms to PC100/PC133 timing and signaling, enabling integration with systems designed around these SDRAM standards.
• Synchronous, pipelined architecture: Registered inputs on the rising clock edge and internal pipelining allow predictable timing and column-address changes every clock cycle.
• Flexible burst operation: Programmable burst lengths (1, 2, 4, 8, full page) let designers tune throughput and latency to match system access patterns.
• Compact package footprint: 54-pin TSOP II (400 mil) package provides a space-efficient surface-mount option for board-level memory integration.
• Commercial temperature support: Specified for 0 °C to +70 °C, suitable for a wide range of commercial electronic applications.
• Single-supply operation: Operates from a single 3.3 V ±0.3 V supply, simplifying power-rail design.

Why Choose IC DRAM 256MBIT PAR 54TSOP II?

The MT48LC16M16A2P-75:D TR provides a straightforward SDR SDRAM solution when a 256 Mbit, 16-bit wide, parallel memory is required. Its synchronous, pipelined operation, PC100/PC133 compliance, and programmable burst modes make it suitable for designs that require deterministic timing and flexible burst transfers within a commercial temperature range.

This device is a practical choice for engineers needing a compact 54-pin TSOP II package, single 3.3 V supply operation, and standard refresh and power-management features. It is appropriate for systems where established SDRAM signaling and interface behavior are required and where the specified timing and thermal ranges meet design constraints.
