Key Features

• Memory Organization & Capacity 67,108,864 bits total, organized as 4 × 1,048,576 words × 16 bits for compact, word-addressable storage.
• SDRAM Architecture & Interface Synchronous DRAM with parallel interface; all inputs sampled on the positive edge of the system clock and four-bank operation for interleaved access.
• Performance Maximum specified clock frequency 143 MHz with 5 ns access time and 14 ns write cycle time (word/page). Supports CAS latency options of 2 and 3.
• Burst Control & Flexibility Programmable burst lengths (1, 2, 4, 8 and full page) and burst types (sequential and interleave) to match diverse transfer patterns.
• Power & I/O JEDEC standard 3.3V power supply and separate VDDQ/VSSQ for isolated data output power and improved noise immunity.
• Refresh & Reliability Auto and self-refresh supported with a 64 ms refresh period (4K cycles) and 15.6 µs refresh interval for data integrity over time.
• Package & Mounting Available in 54 TSOP II and 54 VBGA packages; surface-mount mounting type suited for modern PCB assembly processes.
• Industrial Grade Temperature Qualified for operation from −40 °C to 85 °C for use in temperature-demanding applications.
• Standards & Compliance JEDEC-compliant SDRAM with LVTTL-compatible inputs and DQM data masking support for controlled I/O behavior.

Typical Applications

• Industrial Control Systems High-bandwidth buffer memory for embedded controllers and industrial automation where wide operating temperature is required.
• Networking & Communication Equipment Packet buffering and temporary storage for high-performance networking modules that require synchronous, low-latency memory.
• Video and Graphics Buffers Frame buffering and streaming applications that benefit from burst-mode transfers and programmable latencies.
• Embedded Storage Controllers Working memory for controllers and intermediate data staging in solid-state and storage-related designs.

Unique Advantages

• Industrial Temperature Range: Rated for −40 °C to 85 °C, enabling deployment in harsh and temperature-variable environments.
• Flexible Performance Modes: Support for CAS latency 2 and 3 plus multiple burst lengths provides designers with tuning options to match system timing and throughput needs.
• JEDEC-Compatible Design: JEDEC-standard supply and timing features simplify integration into existing SDRAM memory subsystems and design flows.
• Separate I/O Power Domain: VDDQ/VSSQ isolation for output buffers improves noise immunity and signal integrity in mixed-signal and high-speed designs.
• Multiple Package Options: Choice of 54 TSOP II or 54 VBGA packages supports form-factor flexibility and PCB assembly preferences.
• Built-In Refresh Mechanisms: Auto and self-refresh capabilities with defined refresh timing reduce system-level refresh management complexity.
