IS45S32400F-7TLA2

The IS45S32400F-7TLA2 is a 128 Mbit SDRAM device organized as 4M × 32 with a parallel memory interface. It provides volatile DRAM storage with defined timing and power characteristics for systems that require synchronous parallel memory.

Designed for applications that need mid-density parallel SDRAM, the device combines 143 MHz clocking and a 5.4 ns access time with a compact 86‑TSOP II package and an operating range suited for extended-temperature environments.

Key Features

• Memory Type & Organization 128 Mbit SDRAM organized as 4M × 32, formatted as volatile DRAM for synchronous parallel access.
• Performance Supports a 143 MHz clock frequency with a listed access time of 5.4 ns.
• Interface Parallel memory interface for direct integration into systems requiring synchronous parallel DRAM.
• Power Operates from a 3.0 V to 3.6 V supply range.
• Package Supplied in an 86‑TSOP II package (86‑TFSOP, 0.400", 10.16 mm width) suitable for surface-mount PCB assembly.
• Temperature Range Rated for operation from −40°C to 105°C (TA).

Typical Applications

• Embedded systems — Use as parallel SDRAM storage where 128 Mbit capacity and synchronous access are required.
• Industrial electronics — Extended −40°C to 105°C operating range supports deployment in temperature-challenged environments.
• System memory expansion — Parallel interface and 4M × 32 organization enable integration into designs requiring mid-density DRAM.

Unique Advantages

• Mid-density SDRAM capacity: 128 Mbit organization (4M × 32) provides a balance between capacity and board-level cost for systems needing synchronous DRAM.
• Defined performance: 143 MHz clock frequency and 5.4 ns access time supply measurable timing characteristics for system timing budgets.
• Wide supply tolerance: 3.0–3.6 V operating range accommodates standard 3 V memory power rails.
• Extended temperature rating: −40°C to 105°C operation supports deployment in industrial and other temperature-demanding environments.
• Compact TSOP II package: 86‑TSOP II (0.400", 10.16 mm width) provides a surface-mount footprint for space-constrained PCBs.
