MT48LC16M16A2BG-75 IT:D TR

The MT48LC16M16A2BG-75 IT:D TR is a 256 Mbit volatile SDRAM organized as 16M × 16 with a parallel memory interface. It implements a fully synchronous, pipelined SDRAM architecture targeting PC100/PC133-compliant systems and board-level designs that require a 3.3 V single-supply, high-speed parallel memory solution.

Key attributes include a 133 MHz clock frequency, a compact 54-ball VFBGA package (8 × 14 mm), industrial operating temperature range (−40°C to +85°C), and timing suited for burst and pipelined memory transactions.

Key Features

• Core / Memory Organization — 256 Mbit SDRAM organized as 16M × 16 with four internal banks for row access and precharge management.
• Performance — PC100- and PC133-compliant operation with a 133 MHz clock frequency and an access time listed as 5.4 ns; supports pipelined operation and column address changes every clock cycle.
• Timing & Burst — Programmable burst lengths (1, 2, 4, 8, or full page) and support for auto precharge and auto refresh modes to simplify burst read/write sequencing.
• Refresh & Low-Power Modes — Auto refresh and self refresh capability (not available on AT devices per datasheet options); 8192-cycle refresh supported.
• Interface & I/O — Parallel SDRAM interface with LVTTL-compatible inputs and outputs and a write cycle time (word/page) of 15 ns.
• Power — Single supply voltage range of 3.0 V to 3.6 V (3.3 V nominal).
• Package — 54-ball VFBGA (54-VFBGA, 8 × 14 mm) in a compact BGA footprint for board-level integration.
• Operating Range — Industrial temperature specification from −40°C to +85°C (TA).

Typical Applications

• PC100/PC133-compatible memory subsystems — Use as synchronous DRAM in systems designed around PC100/PC133 timing.
• Board-level parallel memory — Dense 54-ball VFBGA package suited for compact PCBs requiring parallel SDRAM with 16M × 16 organization.
• Industrial embedded systems — Suitable for designs operating across an industrial temperature range (−40°C to +85°C) where a 3.3 V SDRAM is required.

Unique Advantages

• Industry-standard timing compliance: PC100/PC133 compliance simplifies integration into existing PC100/PC133 system architectures.
• Pipelined, synchronous operation: Fully synchronous design with pipelined internal operation allows column addresses to change every clock cycle for predictable throughput.
• Flexible burst and refresh modes: Programmable burst lengths plus auto refresh and self refresh options enable efficient sequential transfers and low-power retention modes.
• Compact BGA footprint: The 54-ball VFBGA (8 × 14 mm) package reduces board area compared with larger packages while delivering a parallel SDRAM interface.
• Industrial temperature rating: −40°C to +85°C operating range supports deployment in temperature-demanding environments.
• Standard 3.3 V supply: Single-supply operation (3.0 V to 3.6 V) aligns with common system power rails for straightforward power design.
