• Performance Specified for 200 MHz operation with CAS latency options 2 and 3; access time 4.5 ns and write cycle time (word/page) 10 ns.
• Burst and Transfer Control Programmable burst lengths (1, 2, 4, 8 & full page) and burst types (sequential & interleave) for flexible data-transfer patterns.
• Synchronous Interface & Timing All inputs sampled on the positive edge of the system clock; LVTTL compatible with multiplexed address lines and support for burst read / single write operations.
• Refresh and Power Management Auto and self-refresh support with a 64 ms refresh period (8K cycle). Operates from 3.0 V to 3.6 V (JEDEC standard 3.3 V).
• Signal Masking and Configuration DQM pins for data masking and MRS cycle for mode programming and address-key configuration.
• Package & Mounting 54-lead TSOP II surface-mount package (TSOPII supplier device package), suitable for compact board-level integration.
• Operating Range & Compliance Commercial grade operation from 0 °C to 70 °C; JEDEC qualification and Pb‑free / RoHS-compliant manufacturing.

Typical Applications

• High-bandwidth memory subsystems — Supports systems that require synchronous DRAM with programmable burst and latency to match varied data throughput requirements.
• Performance-driven embedded platforms — Provides predictable, clocked memory access for designs that depend on tight timing and deterministic transfers.
• Systems requiring JEDEC-standard 3.3V SDRAM — Fits designs that mandate standard-voltage DRAM with refresh and power-management features.

Unique Advantages

• Flexible timing and burst control: Multiple CAS latency options and programmable burst lengths allow tuning for different throughput and latency trade-offs.
• Four-bank architecture: Enables bank interleaving and improved effective throughput for burst-oriented access patterns.
• Robust refresh and power modes: Auto/self-refresh and standard refresh timing (64 ms / 8K) simplify memory maintenance and power management.
• Industry-standard voltage and interface: JEDEC 3.3V compatibility and LVTTL-compatible inputs facilitate integration into standard SDRAM systems.
• Compact surface-mount package: 54-TSOP II footprint provides a space-efficient solution for board-level memory deployment.
• Regulatory and environmental compliance: Pb-free construction and RoHS compliance align with environmental and manufacturing requirements.
