Integrated Silicon Solution, Inc. Memory IS43DR16320C-3DBLI-TR

The IS43DR16320C-3DBLI-TR is a 512Mb DDR2 SDRAM memory chip from Quarktwin Technology Ltd. It operates at a voltage of 1.8V ¬±0.1V and features a double data rate interface, allowing for two data transfers per clock cycle. The device supports a 4-bit prefetch architecture and includes four internal banks for concurrent operations. Programmable CAS latency options of 3, 4, 5, and 6 are available, along with programmable burst lengths of 4 or 8. This memory chip is packaged in an 84-ball WBGA format (8mm x 12.5mm) and is suitable for various temperature ranges, including commercial (0¬8C to 85¬8C), industrial (-40¬8C to 95¬8C), and automotive applications (-40¬8C to 105¬8C). Key timing parameters include a cycle time of 2.5ns at CL=5 for DDR2-800 and 3.0ns at CL=5 for DDR2-667. The device also features on-die termination (ODT) and adjustable data-output drive strength options. This product is designed for high-speed operation and is ideal for applications requiring reliable memory performance.
