IS42S16800J-7TLI-TR

The IS42S16800J-7TLI-TR is a 128 Mbit SDRAM device organized as 8M × 16, supplied in a 54-TSOP II package (0.400", 10.16 mm width). It implements a parallel DRAM architecture with an LVTTL memory interface and a supply voltage range of 3.0 V to 3.6 V.

Targeted for systems that require external SDRAM storage, the device offers a 143 MHz clock frequency and a 5.4 ns access time, and is specified for operation from −40°C to 85°C (TA).

Key Features

• Memory Core 128 Mbit DRAM organized as 8M × 16, providing parallel DRAM storage in a compact footprint.
• Performance Supports a clock frequency of 143 MHz with an access time of 5.4 ns to meet moderate-speed memory requirements.
• Interface LVTTL memory interface for compatibility with TTL signaling domains.
• Power Operates from a 3.0 V to 3.6 V supply range, suitable for standard 3 V DRAM power rails.
• Package 54-TSOP II (0.400", 10.16 mm width) supplier device package for board-level integration where this footprint is required.
• Operating Range Specified for −40°C to 85°C ambient temperature (TA) for use in environments within this range.
• Memory Format Volatile SDRAM memory format intended for temporary system memory and buffering applications.

Typical Applications

• Embedded systems — External SDRAM storage for embedded designs that require a 128 Mbit parallel memory interface.
• Buffer memory — Frame or data buffering where 8M × 16 organization and 143 MHz clocking meet throughput needs.
• Board-level memory expansion — Drop-in DRAM option for designs using the 54-TSOP II package footprint and LVTTL signaling.

Unique Advantages

• Compact TSOP II footprint: The 54-TSOP II package (0.400", 10.16 mm) enables dense board-level placement while maintaining a standard supplier package.
• Measured performance: 143 MHz clocking combined with a 5.4 ns access time provides predictable timing for system memory operations.
• Standard LVTTL interface: Simplifies interfacing to TTL-compatible memory controllers and logic.
• Wide operating voltage range: 3.0 V to 3.6 V operation accommodates common 3 V DRAM power rails.
• Extended ambient temperature: Rated for −40°C to 85°C (TA) to support a range of environmental conditions within that span.
