IS43DR16640B-3DBLI Description

Short technical summary and product information.

The IS43DR16640B-3DBLI is a high-performance 1Gb DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) integrated circuit manufactured by Integrated Silicon Solution. This component operates with a clock frequency of up to 400MHz, supporting efficient data transfer rates for demanding applications.

 

Key features include a 4-bit prefetch architecture, programmable CAS Latency options from 3 to 7, and a write latency set to one clock cycle less than the read latency. The memory organization is 64M x 16, providing a substantial capacity for data storage. It operates within a voltage range of 1.7V to 1.9V, with a nominal supply of 1.8V for VDD and VDDQ.

 

Designed for surface mounting, the IS43DR16640B-3DBLI comes in an 84-TWBGA (8x12.5) package. The operating temperature range is -40°C to 85°C (TA), making it suitable for various industrial and automotive environments. Additional features include Auto Refresh, Self Refresh, Power Down Mode, and On-Die Termination (ODT).

 

This DDR2 SDRAM is well-suited for applications requiring high-speed memory solutions, such as embedded systems, networking equipment, and consumer electronics where performance and density are critical.
