IS42S32400J-6BL

The IS42S32400J-6BL is a 128 Mbit synchronous DRAM (SDRAM) device organized as 4M × 32. It implements a standard SDRAM architecture in a compact 90-TFBGA (8×13) package for board-level memory integration.

Designed for systems that require moderate-speed synchronous DRAM, the device provides a 166 MHz clock capability, LVTTL interface signaling, and a 3.0 V to 3.6 V supply window to simplify power design and integration into existing memory subsystems.

Key Features

• Memory Architecture Organized as 4M × 32 to provide 128 Mbit of SDRAM capacity suitable for 32-bit bus configurations.
• SDRAM Technology Volatile SDRAM memory format supporting synchronous operation for predictable timing.
• Performance 166 MHz clock frequency and a specified access time of 5.4 ns for moderate-speed memory access.
• Interface LVTTL memory interface for logic-level signaling compatibility with common system designs.
• Power Operates from a 3.0 V to 3.6 V supply range to match common 3 V memory power rails.
• Package 90-TFBGA (8×13) package case for compact board mounting and high pin density.
• Operating Temperature Specified for 0°C to 70°C (TA) ambient operating range.

Typical Applications

• Embedded Systems — Provides on-board SDRAM for processors and controllers that require 128 Mbit of external memory in a compact package.
