MT48LC8M16A2B4-6A XIT:L

The MT48LC8M16A2B4-6A XIT:L is a 128 Mbit synchronous DRAM (SDRAM) device organized as 8M × 16 with a parallel memory interface in a 54‑VFBGA (8×8) package. It implements fully synchronous, pipelined SDRAM architecture with internal banks and programmable burst operation for system memory buffering and high‑throughput data transfer.

Targeted at designs that require a 3.3 V supply range and industrial temperature operation, the device delivers up to 167 MHz clock operation with a 5.4 ns access time (–6A timing grade), while offering built‑in refresh and low‑power modes for reliable data retention.

Key Features

• Memory Core & Organization 128 Mbit SDRAM organized as 8M × 16 with internal bank architecture to hide row access and precharge latency.
• Performance & Timing –6A speed grade supports a 167 MHz clock and a 5.4 ns access time (CL = 3 timing), with a 12 ns write cycle time for word‑page writes.
• Interface & Operation Fully synchronous parallel SDRAM with programmable burst lengths (1, 2, 4, 8, or full page), internal pipelined operation, and LVTTL‑compatible inputs/outputs.
• Refresh & Low‑Power Modes Supports Auto Refresh, Concurrent Auto Precharge, and Self Refresh modes with a 64 ms / 4,096‑cycle refresh scheme; low‑power self refresh option available.
• Power Single supply operation at +3.3 V nominal (specified range 3.0 V to 3.6 V).
• Package & Temperature Supplied in a 54‑VFBGA (8×8) package and specified for industrial ambient operation from −40°C to +85°C.
• Standards Compatibility Documented PC100 and PC133 timing options in the product family and documented timing grades for system design.

Unique Advantages

• Parallel SDRAM Interface: Provides a conventional parallel memory bus suitable for systems that require direct SDRAM integration and predictable timing.
• High‑frequency Operation: 167 MHz clock capability and 5.4 ns access time (–6A) enable higher data throughput within the device's specified timing grades.
• Robust Thermal Range: Industrial temperature rating (−40°C to +85°C) supports deployment in environments where extended temperature tolerance is required.
• Integrated Power Modes: Auto Refresh and Self Refresh modes, including low‑power self refresh, reduce external refresh management and support energy‑sensitive designs.
• Compact BGA Package: 54‑VFBGA (8×8) footprint balances board area efficiency with the pinout required for parallel SDRAM applications.
• Single‑Supply Convenience: +3.3 V nominal operation (3.0 V to 3.6 V) simplifies supply rail requirements in legacy and contemporary systems.
