IS42S16160D-75ETLI-TR

The IS42S16160D-75ETLI-TR is a 256Mbit synchronous DRAM (SDRAM) device from ISSI organized as 16M × 16. It implements a pipeline architecture and fully synchronous operation with all signals referenced to the rising edge of the clock, providing a high-speed parallel memory option for designs requiring deterministic clocked access.

Targeted use cases include systems that need fast, burst-capable parallel memory with features such as programmable burst length, programmable CAS latency, internal bank management, and self-refresh. Key value propositions include measured access performance (5.5 ns access time at the -75E grade), support for 133 MHz clocking, and a compact 54-pin TSOP-II package with industrial temperature support.

Key Features

• Memory Core
 The device provides 256 Mbit SDRAM capacity organized as 16M × 16 with internal bank architecture for hidden row access/precharge.
• Performance
 Clock frequency support up to 133 MHz for the -75E grade and an access time of 5.5 ns (CL=2, -75E), enabling high-speed, deterministic read/write timing.
• Programmable Burst & Latency
 Programmable burst length (1, 2, 4, 8, full page) and burst sequence (sequential/interleave), with programmable CAS latency options (2 or 3 clocks) to match system timing requirements.
• Refresh & Self-Refresh
 Auto-refresh and self-refresh support with 8K refresh cycles (timing options per grade), allowing retention during low-power states.
• Interface
 LVTTL-compatible parallel interface designed for fully synchronous operation referenced to the positive clock edge.
• Power
 Single-supply operation within 3.0 V to 3.6 V (typical 3.3 V ±0.3 V) to match common system power rails.
• Package & Temperature
 54-pin TSOP-II package (0.400", 10.16 mm width) with an operating temperature range of -40 °C to +85 °C (TA).

Typical Applications

• High‑speed buffer memory — Use as parallel SDRAM buffering for designs that require pipeline-style, clocked data transfers and burst operations.
• Embedded systems — Local system memory for embedded designs leveraging the device's synchronous LVTTL interface, programmable latency and burst control.
• Industrial equipment — Memory for industrial applications that require operation across a wide temperature range (−40 °C to +85 °C).

Unique Advantages

• Deterministic synchronous operation: Fully synchronous inputs and outputs referenced to the rising clock edge simplify timing and integration into clocked memory subsystems.
• High-speed access: -75E grade access time of 5.5 ns (CL=2) and support for 133 MHz clocking enable fast read/write cycles and efficient burst transfers.
• Flexible burst and latency control: Programmable burst length and CAS latency let designers tune throughput and latency for specific application needs.
• Power and retention features: Single 3.0 V–3.6 V supply and self-refresh/auto-refresh capabilities support low-power retention modes and standard system rails.
• Industrial-temperature capability: Rated for −40 °C to +85 °C (TA), suitable for temperature-sensitive deployments.
• Compact board footprint: 54‑pin TSOP‑II package provides a space-efficient footprint for board-level memory integration.
