- SDRAM Technology Synchronous DRAM core providing standard DRAM interface behavior and timing.
- Performance 143 MHz clock frequency with a 5.4 ns access time to meet timing requirements for systems using external SDRAM.
- Voltage Operates from 3.0 V to 3.6 V, supporting 3.3 V system rails.
- Interface LVTTL-compatible memory interface signaling for integration with compatible system logic levels.
- Package Supplied in an 86-TFSOP (86-TSOP II) package (0.400", 10.16 mm width) for board-level SMT assembly.
- Operating Temperature Rated for -40°C to 85°C (TA), suitable for applications requiring extended temperature operation.
- Memory Type Volatile DRAM storage for temporary system data and buffering.
Typical Applications
- Systems requiring 256 Mbit SDRAM — Use where an 8M × 32 organization and 256 Mbit density match the system memory requirements.
- High-frequency memory interfaces — Applicable to designs that require operation at or near a 143 MHz SDRAM clock and 5.4 ns access timing.
- Extended temperature systems — Appropriate for equipment that operates across -40°C to 85°C and needs external SDRAM in a TSOP II package.
Unique Advantages
- 256 Mbit density: Provides substantial external DRAM capacity in a single 8M × 32 device, reducing the number of DRAM devices required.
- 32-bit data path: Wide data organization supports efficient 32-bit bus transactions and bandwidth utilization.
- 143 MHz clock and 5.4 ns access time: Delivers predictable timing performance for systems designed around specified SDRAM clock rates and access latencies.
- Wide supply range: 3.0 V to 3.6 V operation ensures compatibility with standard 3.3 V system power rails.
- Industry-standard TSOP II package: 86-TFSOP (86-TSOP II) package enables common SMT assembly and board-level integration.
- Extended temperature rating: -40°C to 85°C operation supports designs exposed to a broad ambient temperature span.
