IS42S16160G-6TLI-TR

Memory IC Overview

The IS42S16160G-6TLI-TR is a 256Mb Synchronous DRAM manufactured by ISSI. It features a 16M x 16 organization with a 16-bit data bus width and supports clock frequencies up to 166 MHz. The device utilizes a 54-pin TSOP-II package and operates within a supply voltage range of 3.0V to 3.6V. Designed for industrial applications, it functions reliably between -40°C and +85°C. Key timing specifications include a 6ns access time and a CAS latency of 3 clocks at the specified frequency.

Memory IC Feature Summary

• Fully synchronous interface where all signals are referenced to the positive edge of the system clock.
• Internal bank architecture allows hiding row access and precharge times to enable seamless high-speed random-access operations.
• Supports programmable burst lengths including sequential and interleave sequences for efficient data transfer.
• Includes power-saving modes such as auto refresh, self-refresh, and power-down capabilities.

Memory IC Applications

• High-speed data buffering in embedded systems
• Graphics memory subsystems requiring pipeline architecture
• Industrial control equipment operating in wide temperature ranges
• Consumer electronics utilizing LVTTL compatible interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to the NRND status. Confirm that the specific ordering suffix matches the required industrial temperature grade and tape-and-reel packaging format. Ensure design compatibility with the 54-pin TSOP-II footprint and validate signal integrity for the LVTTL interface before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 256Mb capacity with a 16-bit data path is required for synchronous memory applications. The industrial temperature rating makes it suitable for harsh environments. Consider the 54-pin TSOP-II package constraints regarding board space and thermal dissipation requirements compared to BGA alternatives.

Memory IC Part Context

This part belongs to the IS42S16160G series of 256Mb SDRAMs from Integrated Silicon Solution. It shares architectural similarities with the IS42S83200G but differs in data bus width and internal organization. The '6' designation indicates the 166MHz speed grade, while 'TLI' specifies the industrial temperature range and lead-free TSOP-II packaging configuration.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: IS42S16160B-6TLI-TR (Note: Access time differs at 5.4 ns).

Memory IC FAQ

What is the function of the DQML and DQMH pins?

DQML and DQMH serve as byte masks for the lower and upper bytes of the I/O buffers, controlling read output enablement and write data masking independently.

How does the Auto Precharge feature operate?

Auto Precharge initiates the precharge process at the earliest valid stage within a burst sequence, allowing the accessed row to be closed automatically without an explicit command.
