MT48LC4M16A2B4-7E:J

The MT48LC4M16A2B4-7E:J is a 64 Mbit volatile SDRAM organized as 4M × 16 with a parallel memory interface in a 54-ball VFBGA (8×8) package. It implements fully synchronous SDRAM architecture with internal banks and pipelined operation for predictable, clocked memory access.

Designed for commercial-grade systems, the device operates at a 133 MHz clock frequency, supports a 3.0–3.6 V supply range, and is specified for an ambient operating temperature of 0°C to 70°C, making it suitable for board-level designs that require compact, parallel SDRAM memory.

Key Features

• Memory Architecture 64 Mbit SDRAM organized as 4M × 16 with multiple internal banks to hide row access/precharge and enable pipelined operation.
• Synchronous Operation Fully synchronous SDRAM with all signals registered on the positive edge of the system clock; column address can be changed every clock cycle.
• Performance 133 MHz clock frequency with an access time of 5.4 ns (product data) and a write cycle time (word page) of 14 ns.
• Burst and Refresh Features Programmable burst lengths (1, 2, 4, 8 or full page), auto precharge and auto refresh, plus self-refresh modes as documented in the datasheet.
• Standards Compliance PC100- and PC133-compliant timing options are listed in the product datasheet to support common SDRAM timing profiles.
• Power Single 3.0–3.6 V supply (3.3 V ±0.3 V per datasheet) for integration into standard 3.3 V systems.
• Package and Mounting 54-ball VFBGA (8×8) package for compact, board-level mounting with a parallel interface.
• Temperature Range Commercial operating ambient range 0°C to 70°C.

Typical Applications

• Commercial Electronics — System memory in commercial-grade products that require a compact parallel SDRAM solution within the 0°C to 70°C operating range.
• Embedded Systems — Board-level memory for embedded designs that use synchronous parallel DRAM and require 64 Mbit density at 133 MHz operation.
• Legacy Parallel-Memory Designs — Replacement or upgrade memory for systems designed around parallel SDRAM architectures.
• Space-Constrained PCBs — Compact 54-ball VFBGA (8×8) package suited to high-density layouts.

Unique Advantages

• Compact VFBGA package: 54-ball 8×8 VFBGA minimizes board footprint while providing parallel memory connectivity.
• Synchronous, pipelined architecture: Internal banks and pipelined operation allow column address updates every clock cycle for efficient memory throughput.
• Flexible timing and burst control: Programmable burst lengths and PC100/PC133 timing options enable designers to balance throughput and latency.
• Robust power tolerance: 3.0–3.6 V supply range (3.3 V ±0.3 V) supports typical 3.3 V system margins.
• Commercial-grade specification: Specified for 0°C to 70°C operation for deployments in commercial environments.
