Memory IC datasheet and documents for IS49NLS18160A-25WBLI
Memory IC Overview
The IS49NLS18160A-25WBLI is a 288 Mbit RLDRAM2 dynamic random-access memory manufactured by ISSI. It features an 18-bit data bus width and utilizes separate I/O architecture. The device supports a maximum clock frequency of 400 MHz with a tRC of 15 ns. It is housed in a WBGA-144 package and operates within a voltage range of 2.38 V to 2.63 V. The component is rated for industrial temperature conditions, functioning between -40°C and +85°C.
Memory IC Feature Summary
- Supports high-speed data transfer via 400 MHz clock operation
- Utilizes separate input/output architecture for signal integrity
- Designed for industrial temperature environments
Memory IC Applications
- High-performance networking equipment
- Telecommunications infrastructure
- Industrial control systems
Memory IC Procurement Notes
Verify the specific suffix 'WBLI' against official ISSI documentation to confirm package type and environmental rating. Ensure compatibility with existing board designs regarding the WBGA-144 footprint. Confirm that the separate I/O configuration aligns with system requirements. Check for any lead time variations due to manufacturing status.
Memory IC Selection Notes
Select this component when a 288 Mbit capacity with 18-bit width is required. The separate I/O design is suitable for applications demanding reduced noise coupling. The 400 MHz speed class meets high-bandwidth needs. Verify thermal management capabilities for the specified industrial temperature range.
Memory IC Part Context
This part belongs to the IS49NLS18160 series of RLDRAM2 devices. It shares architectural similarities with other members of the family but differs in speed grade and packaging. The 'S' indicates separate I/O, distinguishing it from common I/O variants like the IS49NLC series.
Memory IC Replacement Considerations
Direct substitutes include other ISSI RLDRAM2 parts with matching 288 Mbit capacity and 18-bit width. Verify pinout compatibility before substitution. Consider speed grade differences if replacing with faster or slower variants.
