IS46DR81280C-3DBLA2

Memory IC Overview

The IS46DR81280C-3DBLA2 is a 1Gb (128M x 8) DDR2 SDRAM manufactured by ISSI. It operates at a maximum clock frequency of 333 MHz with an access time of 450 ps. The device utilizes a 1.8V supply voltage and features an 84-ball TFBGA package measuring 8x12.5 mm. It supports programmable CAS latencies and burst lengths for flexible system integration.

Memory IC Feature Summary

• Supports double data rate interface with two data transfers per clock cycle
• Features eight internal banks for concurrent operation
• Includes on-die termination and differential data strobe capabilities

Memory IC Applications

• Automotive infotainment systems
• Industrial control memory buffers
• Consumer electronics display interfaces

Memory IC Procurement Notes

Verify the specific suffix 'BLA2' against the manufacturer's official datasheet to confirm package dimensions and pinout compatibility. Ensure the component meets required automotive or industrial temperature standards if deployed in harsh environments. Cross-reference ordering information directly with ISSI documentation to avoid discrepancies.

Memory IC Selection Notes

Select this component when a 1Gb density with an 8-bit bus width is required. The 333 MHz speed grade suits applications needing moderate bandwidth. Consider the 84-ball TFBGA form factor for space-constrained PCB layouts requiring surface mount technology.

Memory IC Part Context

This part belongs to the IS46DR series of DDR2 SDRAMs from ISSI. It shares architectural similarities with other members like the IS46DR16128C but differs in organization and density. The series is designed for high-performance parallel memory applications requiring low power consumption.
