IS42S16400F-7TLI

Memory IC Overview

The IS42S16400F-7TLI is a 64Mb Synchronous DRAM organized as 4M x 16. It operates with a single 3.3V power supply and features an LVTTL interface. The device supports clock frequencies up to 143 MHz, corresponding to a cycle time of 7 ns. Access time from the clock edge is 5.5 ns. It utilizes a 54-pin TSOP II package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports internal bank interleaving to hide row access and precharge times for improved performance.
• Features programmable burst lengths including sequential and interleave sequences.
• Includes auto-refresh and self-refresh modes for data retention and power management.

Memory IC Applications

• High-speed data transfer in pipeline architectures
• Systems requiring synchronous dynamic random-access memory
• Industrial embedded applications

Memory IC Procurement Notes

Verify the specific suffix '7TLI' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the required operating temperature grade matches the industrial specification (-40°C to +85°C). Confirm that the system design accommodates the 54-pin TSOP II package dimensions and soldering requirements.

Memory IC Selection Notes

Select this component when a 64Mb density with a 16-bit data bus width is required. It is suitable for designs needing a 3.3V supply and LVTTL logic levels. Consider the 143 MHz maximum frequency and 5.5 ns access time for timing constraints. Verify that the 54-pin TSOP II form factor fits the available PCB space.

Memory IC Part Context

This part belongs to the IS42S16400F series of 64Mb SDRAMs manufactured by ISSI. The series offers various speed grades and package options, including FBGA. The F suffix typically denotes the commercial or industrial temperature grade variants within the product line.

Memory IC Replacement Considerations

Check for other speed grades within the IS42S16400F family, such as those supporting higher clock frequencies, if system timing allows. Verify pin-to-pin compatibility with alternative manufacturers offering similar 64Mb 16-bit SDRAMs in 54-pin TSOP packages.
