MT48LC4M16A2B4-6A:J TR

The MT48LC4M16A2B4-6A:J TR is a 64 Mbit volatile SDRAM organized as 4M x 16 in a 54-ball VFBGA package. It provides a fully synchronous parallel memory interface for systems that require compact, board-level DRAM in a commercial temperature range.

Targeted at designs that need synchronous SDRAM performance and a small BGA footprint, this device offers 167 MHz clock operation, low access latency, and a single 3.3 V power domain for straightforward integration into legacy and embedded platforms supporting PC100/PC133 family features.

Key Features

• Memory Architecture — 64 Mbit DRAM organized as 4M × 16 with internal bank architecture to support pipelined, synchronous operation.
• SDR SDRAM Operation — Fully synchronous SDRAM with programmable burst lengths and internal pipelined operation as documented for the MT48LCxMxA2 family.
• Speed and Timing — Rated for 167 MHz clock frequency; documented -6A timing shows 3-3-3 RCD-RP-CL targeting 18 ns for RCD, RP and CL. Specification lists an access time of 5.4 ns and a write cycle time (word/page) of 12 ns.
• Voltage Supply — Single supply operation from 3.0 V to 3.6 V (nominal 3.3 V) for compatibility with standard 3.3 V systems.
• Package — 54-ball VFBGA (8 mm × 8 mm) package for compact board-level integration and reduced footprint.
• Refresh and Power Modes — Supports auto refresh and self-refresh modes described for the family, including 4K refresh cycles; single-supply LVTTL-compatible I/Os as defined in the family specification.
• Operating Range — Commercial temperature range: 0°C to +70°C (TA), suitable for commercial-grade applications.

Typical Applications

• Legacy and PC-compatible systems — Use as synchronous DRAM in applications that require PC100/PC133 family compatibility and parallel SDRAM interfaces.
• Embedded systems — Compact board-level DRAM for embedded controllers and modules where a 54-ball VFBGA footprint and single 3.3 V supply are required.
• Consumer electronics — On-board memory for devices operating in commercial temperature ranges that need synchronous, burst-capable DRAM.

Unique Advantages

• Compact VFBGA package: 54-ball, 8 mm × 8 mm footprint reduces PCB area for space-constrained designs.
• Synchronous parallel interface: Fully synchronous SDRAM architecture enables pipelined column operations and programmable burst lengths for predictable timing behavior.
• High-frequency operation: 167 MHz clock rating (–6A) supports systems needing higher throughput within the family’s documented timing options.
• Single 3.3 V supply: 3.0 V to 3.6 V operation simplifies power rail requirements and integration with standard 3.3 V logic.
• Commercial temperature support: Specified 0°C to +70°C operating range for commercial-grade deployments.
