IS42S16400D-7TLI-TR

Memory IC Overview

The IS42S16400D-7TLI-TR is a 64Mb Synchronous DRAM organized as 1 Megabit x 16 Bits x 4 Banks. It operates with a single 3.3V power supply and features an LVTTL interface. The device supports clock frequencies of 166 MHz and 143 MHz, achieving high-speed data transfer via pipeline architecture. Inputs and outputs are referenced to the positive clock edge. It includes programmable burst lengths (1, 2, 4, 8, full page), CAS latencies (2, 3 clocks), and byte control via LDQM and UDQM pins.

Memory IC Feature Summary

• Fully synchronous operation with all signals referenced to the positive clock edge
• Internal bank architecture for hiding row access and precharge times
• Programmable burst length and sequence options including sequential and interleave modes
• Supports self-refresh modes and automatic refresh cycles every 64 ms

Memory IC Applications

• High-speed data transfer systems requiring pipeline architecture
• Memory systems utilizing 3.3V power supplies
• Applications requiring interleaved bank access for seamless random-access operations

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the temperature grade matches industrial requirements if operating outside commercial ranges. Ensure the ordering part number aligns with the 54-pin TSOP II package configuration documented in the official datasheet before finalizing procurement orders.

Memory IC Selection Notes

Select this component for designs requiring a 64Mb capacity with a 16-bit data bus width. It is suitable for applications needing flexible burst configurations and byte-level masking capabilities. Consider the available clock speeds and CAS latency options to match system timing constraints. Verify that the LVTTL interface compatibility meets the controller's voltage levels.

Memory IC Part Context

This device belongs to ISSI's 64Mb SDRAM family, designed for high-performance memory applications. It utilizes a quad-bank internal structure to improve throughput by allowing concurrent operations across different banks. The technology supports both commercial and industrial temperature ranges, providing flexibility for various environmental conditions.

Memory IC Replacement Considerations

Check for IS42S16400E variants which share similar organizational structures but may differ in specific electrical characteristics or package availability. Ensure any substitute maintains the 16-bit width and 4-bank architecture to preserve system compatibility without redesigning the memory interface.
