IS42S86400F-7TL

The IS42S86400F-7TL is a 512 Mbit volatile SDRAM organized as 64M × 8 with a parallel memory interface. Designed for systems that require compact, synchronous dynamic RAM, it delivers predictable timing and a defined operating range for integration into board-level designs.

Key attributes include a 143 MHz clock frequency, 5.4 ns access time, a 3.0–3.6 V supply window, and a 54‑lead TSOP II package (0.400" / 10.16 mm width), making it suitable where board space and standard SDRAM interfacing are primary considerations.

Key Features

• Memory Type Volatile SDRAM organized as 64M × 8 (512 Mbit) for use as parallel dynamic memory storage.
• Performance Specified for operation at a 143 MHz clock frequency with a 5.4 ns access time for synchronous memory transactions.
• Interface Parallel memory interface compatible with standard DRAM bus architectures.
• Power Operates from a 3.0 V to 3.6 V supply range, enabling use in 3.3 V class systems.
• Package Supplied in a 54‑TSOP II package (0.400" / 10.16 mm width) for compact board-level mounting.
• Temperature Range Specified operating ambient temperature of 0 °C to 70 °C (TA).

Typical Applications

• Parallel memory subsystems — Acts as system DRAM where a 64M × 8 parallel SDRAM device is required for temporary data storage.
• Board-level memory expansion — Adds 512 Mbit of SDRAM capacity in designs that accept a 54‑TSOP II footprint and parallel interface.
• Intermediate buffering and frame storage — Provides synchronous volatile storage for applications needing defined access timing and throughput at the specified clock frequency.

Unique Advantages

• 512 Mbit density: Provides a 64M × 8 organization to meet moderate-capacity memory requirements without multiple devices.
• Defined timing performance: 143 MHz clock frequency and 5.4 ns access time enable predictable SDRAM transaction timing.
• 3.0–3.6 V supply compatibility: Matches common 3.3 V system rails for straightforward power integration.
• Compact TSOP II package: 54‑lead TSOP (10.16 mm width) conserves board area while supporting standard surface-mount assembly.
• Parallel interface: Straightforward integration into designs that use conventional DRAM bus signaling.
