IS42S32400J-7TL-TR

The IS42S32400J-7TL-TR is a 128 Mbit SDRAM organized as 4M × 32, designed as volatile DRAM memory for digital systems. It offers a 143 MHz clock capability and a 5.4 ns access time in an 86-pin TSOP II package.

This device is suitable for designs requiring mid-density SDRAM with a LVTTL interface and a 3.0 V to 3.6 V supply range, operating across a commercial temperature range (0°C to 70°C). The compact 86-TFSOP package supports board-space constrained applications.

Key Features

• Memory Technology SDRAM volatile memory with a total capacity of 128 Mbit (4M × 32 organization), provided as DRAM format.
• Performance Operates up to a 143 MHz clock frequency with an access time of 5.4 ns for responsive data access.
• Interface LVTTL memory interface for standard logic-level signaling.
• Power Nominal supply range of 3.0 V to 3.6 V to support common 3 V system rails.
• Package Supplied in an 86-pin TSOP II / 86-TFSOP package (0.400", 10.16 mm width) for compact PCB implementation.
• Operating Range Commercial ambient operating temperature specified from 0°C to 70°C (TA).

Typical Applications

• System Memory Use as external SDRAM in designs requiring 128 Mbit capacity with 4M × 32 organization and LVTTL signaling.
• Buffering and Frame Storage Suitable for buffer or temporary frame storage where a 143 MHz clock and 5.4 ns access time meet system timing requirements.
• Memory Expansion Integration as a mid-density DRAM option for expanding working memory in compact, board-level implementations using an 86-TSOP II footprint.

Unique Advantages

• Right-sized Capacity: 128 Mbit density (4M × 32) provides a balance between capacity and footprint for mid-range memory needs.
• Competitive Access Performance: 5.4 ns access time combined with support for a 143 MHz clock enables responsive read/write cycles.
• Standard LVTTL Interface: Simplifies integration with systems using common logic-level signaling.
• 3.0–3.6 V Supply Flexibility: Compatible with common 3 V system rails, easing power supply design choices.
• Compact TSOP II Package: The 86-TFSOP (0.400", 10.16 mm width) package reduces PCB area while providing a standard mounting footprint.
• Commercial Temperature Range: Specified for 0°C to 70°C ambient operation to match typical commercial applications.
