IS42S16400D-6BLI-TR

Memory IC Overview

The IS42S16400D-6BLI-TR is a 64Mb Synchronous DRAM organized as 4M x 16 with four internal banks. It operates on a single 3.3V power supply and supports clock frequencies of 166 MHz and 143 MHz. The device utilizes an LVTTL interface and features programmable burst lengths, CAS latencies, and sequences. It is available in a 60-ball fBGA package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports fully synchronous operation with all signals referenced to the positive clock edge.
• Includes internal bank architecture to hide row access and precharge times for improved performance.
• Features programmable burst lengths (1, 2, 4, 8, full page) and selectable sequential or interleave burst sequences.
• Provides self-refresh modes and power-saving power-down capabilities.

Memory IC Applications

• High-speed data transfer systems requiring pipeline architecture
• Memory systems utilizing 3.3V logic levels
• Industrial applications requiring extended temperature range support

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. Confirm RoHS compliance status and lead-free availability directly with the manufacturer or authorized distributors before placing orders. Ensure the required clock frequency matches the specific variant ordered.

Memory IC Selection Notes

Select this component for designs requiring a 64Mb capacity with a 16-bit data bus width. Choose based on the required operating temperature range and physical footprint constraints. Verify that the system voltage aligns with the 3.3V requirement and that the interface logic is compatible with LVTTL standards.
