IS42S16400N-7BLI

Memory IC Overview

The IS42S16400N-7BLI is a 64 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by ISSI. It features a 4M x 16 organization with a 16-bit data bus width and supports clock frequencies up to 143 MHz. The device operates on a single 3.3V power supply within a 3V to 3.6V range and utilizes LVTTL interface standards. Packaged in a 54-ball TFBGA measuring 8mm x 8mm, it offers an access time of 5.4 ns and functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports programmable burst lengths including 1, 2, 4, 8, or full page operations for flexible data transfer configurations.
• Features CAS latency options of 2 or 3 cycles to optimize timing performance for specific system requirements.
• Includes automatic refresh modes requiring 4096 cycles every 64ms and self-refresh capabilities for low-power standby states.

Memory IC Applications

• Wireless access points and base stations
• Network routers and storage systems
• Industrial control equipment

Memory IC Procurement Notes

Verify the exact suffix against official datasheets to confirm package dimensions and thermal characteristics. Ensure compatibility with LVTTL logic levels and check RoHS compliance status for environmental regulations. Confirm availability through authorized distributors as stock levels fluctuate. Validate that the selected component matches the required 54-ball BGA footprint for PCB integration.

Memory IC Selection Notes

Select this component when a 64 Mbit density with a 16-bit interface is required for high-speed parallel data processing. Consider the 5.4 ns access time and 143 MHz capability for bandwidth-intensive applications. Verify that the operating voltage range aligns with the system's 3.3V supply rails and that the industrial temperature range meets environmental constraints.

Memory IC Part Context

This part belongs to the IS42S16400 series of SDRAM devices from ISSI. These components are designed for general-purpose memory applications requiring reliable synchronous operation. The series typically includes variants with different access times and packaging options to suit diverse embedded design needs while maintaining standard SDRAM command sets.

Memory IC Replacement Considerations

Check for IS42S16400J-7BLI as a potential alternative, noting its discontinued status. Verify pinout and electrical specifications against current datasheets before substitution. Ensure any replacement maintains the same 54-ball BGA package and 16-bit organization.
