IS42S32400F-7BLI

The IS42S32400F-7BLI is a 128 Mbit volatile SDRAM organized as 4M × 32, delivered in a 90‑TFBGA (8×13) package. It provides a parallel memory interface with a rated clock frequency of 143 MHz and an access time of 5.4 ns.

This device is intended for systems that require external parallel SDRAM storage within a 3.0 V to 3.6 V supply range and operation across an extended ambient temperature range of −40°C to 85°C (TA).

Key Features

• Memory Type: Volatile SDRAM — standard dynamic RAM architecture for external system memory.
• Density & Organization: 128 Mbit, organized as 4M × 32 — supports 32‑bit wide data paths for parallel memory systems.
• Performance: 143 MHz clock frequency with 5.4 ns access time — suitable for designs targeting this timing envelope.
• Interface: Parallel memory interface — designed for direct connection to parallel SDRAM controllers.
• Voltage Supply: 3.0 V to 3.6 V operation — compatible with standard 3 V SDRAM power rails.
• Package: 90‑TFBGA (8×13) — compact ball grid array footprint for surface mounting.
• Operating Temperature: −40°C to 85°C (TA) — supports extended ambient temperature operation.

Typical Applications

• Parallel SDRAM memory subsystems — used where a 128 Mbit parallel SDRAM block with 4M × 32 organization is required.
• Board-level external system memory — suitable for designs that integrate an external SDRAM device operating at 143 MHz clock rates.
• Temperature-sensitive deployments — applicable to systems requiring operation across −40°C to 85°C ambient temperatures.

Unique Advantages

• Clear density and organization: 128 Mbit arranged as 4M × 32 simplifies integration into 32‑bit parallel memory buses.
• Defined performance envelope: 143 MHz clock and 5.4 ns access time provide explicit timing targets for system design and validation.
• Standard 3 V supply compatibility: Operates from 3.0 V to 3.6 V, matching common SDRAM power rails and simplifying power-supply design.
• Compact BGA package: 90‑TFBGA (8×13) offers a space-efficient mounting option for high-density boards.
• Extended temperature range: −40°C to 85°C (TA) supports deployments across a broad ambient range without additional qualification notes in the product data.
