W25R128JWPIQ TR

Memory IC Overview

The W25R128JWPIQ TR is a 128 Mbit NOR Flash memory device manufactured by Winbond Electronics. It utilizes an SPI interface with a maximum clock frequency of 104 MHz and operates within a supply voltage range of 1.7 V to 1.95 V. The memory organization is specified as 16M x 8 bits. The component is housed in an 8-WSON (6x5 mm) package with exposed pad, designed for surface mount technology. It supports standard SPI communication protocols for data storage and retrieval.

Memory IC Feature Summary

• Supports standard Serial Peripheral Interface (SPI) communication protocols
• Operates at low voltage levels suitable for power-constrained systems
• Provides non-volatile data retention capabilities

Memory IC Applications

• Embedded systems requiring code execution from flash memory
• Industrial control modules needing reliable firmware storage
• Consumer electronics utilizing low-power serial flash interfaces

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when ordering. Confirm the 1.8V operating voltage requirement aligns with target system power rails. Check current lifecycle status directly with Winbond Electronics as availability may vary. Ensure ESD protection measures are implemented during handling due to sensitive CMOS construction.

Memory IC Selection Notes

Select this part when a 128 Mbit capacity is required with strict low-voltage constraints between 1.7 V and 1.95 V. Choose over higher-voltage variants if system power budget is limited. Consider the 8-WSON package size for compact PCB layouts where SOIC-8 footprint is unavailable. Verify interface compatibility with host microcontrollers supporting standard SPI modes.

Memory IC Part Context

This component belongs to the W25R128 series of NOR Flash memories, distinct from the W25Q series which supports Quad I/O and higher speeds. The 'R' designation typically indicates support for standard SPI only, lacking dual or quad mode enhancements found in other family members. It serves as a cost-effective solution for applications prioritizing basic serial access over high-throughput data transfer rates.

Memory IC Replacement Considerations

Direct pin-compatible substitutes include W25R128JVSIQ TR, though voltage ranges differ significantly. Verify electrical specifications carefully before substitution. Generic 128 Mbit SPI NOR flashes may not match exact timing or voltage characteristics.
