Memory IC Overview

The IS42S16160D-7BL is a 256Mb Synchronous DRAM manufactured by ISSI. It features a 16-bit data bus width and operates at a maximum clock frequency of 143 MHz. The device utilizes a 54-ball BGA package and supports an access time of 5.4 ns. It functions within a voltage range of 3V to 3.6V and is designed for commercial temperature environments ranging from 0°C to +70°C.

Memory IC Feature Summary

Fully synchronous operation with all signals referenced to the positive clock edge
Internal bank architecture enables row access hiding and precharge operations
Supports programmable burst lengths including sequential and interleave sequences
Includes auto refresh and self-refresh modes for power management

Memory IC Applications

High-speed data transfer systems utilizing pipeline architecture
Memory subsystems requiring interleaved bank access
Applications necessitating random column address changes during burst access

Memory IC Procurement Notes

Verify the specific suffix 'BL' against official datasheets to confirm package type and temperature grade. Confirm that the -7 speed grade aligns with system timing requirements. Check current lifecycle status as distribution availability varies. Ensure moisture sensitivity handling protocols are followed upon receipt.

Memory IC Selection Notes

Select this component when a 16-bit interface is required for 256Mb density. Verify compatibility with LVTTL logic levels for the host controller. Ensure the operating environment remains within the specified commercial temperature limits. Confirm that the 54-ball BGA footprint matches the PCB layout constraints.
