W957D8MFYA5I TR

Memory IC Overview

The W957D8MFYA5I TR is a 128Mb HyperRAM IC featuring an 8-bit data bus and a 24-ball TFBGA DDP package. It operates at a maximum clock rate of 200MHz with DDR up to 400 MT/s, supporting a sustained data rate of 400 MB/s. The device utilizes a 1.7V to 2.0V power supply and functions within a temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports Dual-Die-Package (DDP) architecture for high-density integration
• Features configurable burst characteristics including linear and wrapped modes
• Includes Hybrid Sleep Mode and Deep Power Down for power conservation
• Provides partial array refresh capabilities alongside full array refresh

Memory IC Applications

• High-speed embedded memory systems requiring low signal count interfaces
• Graphics image processing applications utilizing large contiguous data transfers
• Critical word first cache line fill read transactions in processor designs
• Industrial control systems operating within extended temperature ranges

Memory IC Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging when sourcing components. Confirm that the voltage specification aligns with the 1.7V to 2.0V requirement for the D-series part number. Ensure compatibility with the 24-ball TFBGA footprint during PCB layout planning.

Memory IC Selection Notes

Select this component for designs requiring a compact 8-bit interface with high throughput. Consider the DDP package structure if space constraints limit board area. Evaluate the power saving modes against system standby requirements to optimize energy consumption during idle periods.

Memory IC Part Context

This device belongs to the Winbond W957x8MFYA series of 128Mb HyperRAM memories. It shares the same physical package and interface protocol as the W957A8MFYA variant, differing primarily in the required supply voltage level. The series supports both single-ended and differential clock configurations.

Memory IC Replacement Considerations

W957A8MFYA5I serves as a direct functional substitute with identical pinout and performance, differing only in the supported supply voltage range.
