IS43TR16256A-093NBL

Memory IC Overview

The IS43TR16256A-093NBL is a 4 Gbit DDR3 SDRAM manufactured by ISSI. It features a 256M x 16 organization and operates at a maximum clock frequency of 933 MHz, supporting data transfer rates up to 1866 MT/s. The device utilizes a 96-ball BGA package with surface mount installation. Standard voltage operation requires VDD and VDDQ between 1.425 V and 1.575 V. It supports an industrial temperature range from -40°C to +95°C.

Memory IC Feature Summary

• Supports high-speed data transfers with system frequencies up to 1066 MHz
• Features eight internal banks for concurrent operations
• Includes programmable CAS latency, additive latency, and burst length settings
• Provides dynamic on-die termination (ODT) and write leveling capabilities

Memory IC Applications

• Industrial computing systems requiring wide memory interfaces
• Automotive electronic control units operating in extended temperature ranges
• High-performance embedded storage solutions
• Network infrastructure equipment

Memory IC Procurement Notes

Verify the specific suffix NBL against official datasheets to confirm package dimensions and pinout compatibility. Confirm that the standard 1.5V supply requirements align with the target system design. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Check current availability status as legacy components may have limited stock or discontinuation notices.

Memory IC Selection Notes

Select this component when a 16-bit wide interface is required for 4 Gbit capacity. It is suitable for applications needing industrial temperature stability (-40°C to +95°C). Compare against DDR3L variants if lower power consumption is critical, as this model uses standard 1.5V. Ensure the PCB layout supports the 96-ball BGA footprint and signal integrity requirements for 1866 MT/s speeds.

Memory IC Part Context

This part belongs to the IS43TR16256A series of 4Gb DDR3 SDRAMs from ISSI. The series offers various speed grades and packaging options. The 'A' designation typically indicates standard voltage operation. This specific model provides a balance of performance and reliability for demanding environments.

Memory IC Replacement Considerations

Check for IS43TR16256A-107MBLI for higher speed grades. Verify IS43TR16256B series for updated manufacturing revisions. Consult ISSI documentation for direct pin-compatible alternatives within the same family.
