Memory IC Procurement Notes

Verify the specific suffix TBLA1 against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Ensure the ordering quantity aligns with the standard factory pack size of 2000 units. Confirm RoHS compliance status directly with the supplier documentation prior to final procurement decisions.

Memory IC Selection Notes

Select this component when an 8 Gbit density is required for automotive memory applications. The 16-bit data bus width suits wide-memory architectures. Consider the 1.2V operating voltage for power-constrained designs. Verify that the 96-ball BGA footprint fits the PCB layout constraints and that the -40°C to +95°C temperature range meets the system's environmental specifications.

Memory IC Part Context

This part belongs to the IS46QR series of automotive DDR4 SDRAMs from ISSI. The series includes variants with different densities and speeds, such as the IS46QR16256B and IS46QR81024A. These devices are designed to meet the reliability standards required for automotive electronics, offering high performance and low power consumption compared to previous generation memories.

Memory IC Replacement Considerations

Direct substitutes include other parts within the IS46QR family, such as the IS46QR16512B, which offers higher speed options. Cross-referencing with equivalent automotive DDR4 parts from other manufacturers requires careful verification of pin compatibility and timing parameters.
