IS42SM16160E-75BLI

Memory IC Overview

The IS42SM16160E-75BLI is a mobile SDRAM memory IC manufactured by ISSI. It features a storage capacity of 512 Mbit organized as 16M x 32 bits. The device supports a maximum clock frequency of 133 MHz with an access time of 6 ns. It operates on a parallel interface and requires a supply voltage between 2.7 V and 3.6 V. The component is housed in a BGA-90 package and is designed for surface mount installation.

Memory IC Feature Summary

• Mobile synchronous DRAM technology optimized for low power consumption
• Fully synchronous operation referenced to the positive edge of the clock
• Internal pipelined data paths to achieve high bandwidth
• Compatible with LVCMOS input and output voltage levels

Memory IC Applications

• Portable consumer electronics
• Mobile communication devices
• Embedded systems requiring compact memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'E' against the manufacturer's datasheet to confirm voltage and speed grades, as variations exist within the IS42SM series. Ensure the BGA-90 footprint matches the target PCB design. Confirm RoHS compliance status with the supplier prior to ordering, as manufacturing processes may update environmental certifications over time.

Memory IC Selection Notes

Select this component when a 512 Mbit density with a 32-bit bus width is required for mobile applications. The 133 MHz speed grade suits standard SDR-133 interfaces. Consider the BGA-90 package constraints for board space. Compare against the IS42VM series if lower voltage operation is needed, or the IS42RM series for different refresh characteristics.

Memory IC Part Context

This part belongs to the IS42SM family of mobile SDRAMs from ISSI. These devices are engineered for battery-powered applications, offering reduced power consumption compared to standard desktop SDRAMs. The family typically includes variants with different densities and bus widths, all sharing similar synchronous architecture and LVCMOS compatibility.

Memory IC Replacement Considerations

The IS42VM32160E-75BLI is listed as a substitute. Verify that the 1.7V–1.95V operating voltage of the VM variant is compatible with the system design, as it differs from the 2.7V–3.6V range of the SM variant.
