IS43TR16128AL-15HBL

Memory IC Overview

The IS43TR16128AL-15HBL is a 2Gb DDR3 SDRAM component manufactured by ISSI. It features a 128M x 16 organization and operates at a standard voltage of 1.5V ± 0.075V, with low-voltage support at 1.35V (+0.1V/-0.067V). The device supports system frequencies up to 933 MHz (DDR3-1866M speed bin) and utilizes a 96-ball FBGA package measuring 9mm x 13mm. It includes an asynchronous RESET pin, dynamic ODT, and programmable CAS latency.

Memory IC Feature Summary

• Supports high-speed data transfer rates with system frequencies up to 933 MHz.
• Features eight internal banks for concurrent operation and an 8n-bit pre-fetch architecture.
• Includes programmable parameters such as CAS Latency, Additive Latency, Burst Length, and Burst Sequence.
• Provides dynamic On-Die Termination (ODT) and Off-Chip Driver Impedance Adjustment (OCD).

Memory IC Applications

• High-performance computing systems requiring fast memory access
• Graphics processing units and display controllers
• Industrial control applications operating in extended temperature ranges

Memory IC Procurement Notes

Verify the specific speed bin suffix (e.g., HBL) against the required JEDEC speed grade, as performance varies across options like 187F, 15H, 125K, and 107M. Confirm that the ordering suffix corresponds to the intended voltage mode (Standard vs. Low Voltage) and package type. Ensure compatibility with the host controller's supported CAS latencies and burst lengths before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2Gb capacity with a 16-bit data bus width is required. Choose the AL variant specifically if low-voltage (1.35V) operation is necessary alongside backward compatibility with 1.5V systems. Consider the industrial or automotive temperature ratings if the application environment exceeds commercial limits. Verify that the 96-ball FBGA package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the IS43/46TR16128A(L) family of DDR3 SDRAMs from Integrated Silicon Solution, Inc. The 'IS43' prefix denotes the DDR3 technology, while '16128' indicates the 128M x 16 organization. The 'L' suffix specifies the inclusion of low-voltage capabilities. This family shares architectural similarities with the IS46 series but differs in specific feature sets and target markets.

Memory IC Replacement Considerations

Direct replacements must match the 128M x 16 organization, 2Gb density, and 96-ball FBGA package. Verify that any substitute supports the same speed bin (up to 933 MHz) and voltage requirements. Check for compatible mode register settings and timing parameters to ensure seamless integration without hardware modifications.
