IS42S32800L-7TLI

The IS42S32800L-7TLI is a 256 Mbit volatile SDRAM organized as 8M × 32, designed to provide synchronous dynamic memory in systems requiring external DRAM. It operates from a 3.0 V to 3.6 V supply and supports a 143 MHz clock frequency with a 5.4 ns access time, making it suitable where defined SDRAM performance and a compact TSOP-II package are required.

Key Features

• Memory Architecture 256 Mbit SDRAM organized as 8M × 32 bits (DRAM format) for synchronous dynamic memory requirements.
• Performance Supports a 143 MHz clock frequency and a 5.4 ns access time for timing-sensitive memory access within specified parameters.
• Voltage Range Operates from 3.0 V to 3.6 V, enabling compatibility with conventional 3.3 V system supplies.
• Interface LVTTL memory interface signaling for integration with LVTTL-compatible memory controllers and logic.
• Package Supplied in an 86-TSOP II (86-TFSOP, 0.400", 10.16 mm width) package for compact board-level implementation.
• Operating Temperature Specified for −40 °C to 85 °C (TA), supporting deployment across a wide ambient temperature range.

Typical Applications

• Embedded systems — Use as external SDRAM for systems that require a 256 Mbit synchronous memory device with LVTTL interface.
• Board-level memory expansion — Suitable for designs needing a compact TSOP-II packaged DRAM to increase system memory capacity.
• Industrial equipment — Can be applied in equipment requiring components rated for −40 °C to 85 °C operating temperature.

Unique Advantages

• High-density memory — 256 Mbit capacity (8M × 32) provides significant on-board storage in a single device.
• Defined timing performance — 143 MHz clock frequency and 5.4 ns access time give measurable SDRAM timing characteristics for system timing budgets.
• Standard 3.3 V compatibility — Operates across a 3.0 V to 3.6 V range for use with common 3.3 V designs.
• Compact package — 86-TSOP II / 86-TFSOP package (0.400", 10.16 mm width) supports space-constrained PCB layouts.
• Wide temperature rating — −40 °C to 85 °C operating range supports a variety of ambient environments.
• Established manufacturer — Produced by Integrated Silicon Solution Inc (ISSI), providing a known supply source for the part.

Why Choose 256M, 3.3V, SDRAM, 8MX32, 143MHZ?
