IS25LQ080-JVLE Equivalent & Substitute Parts

Part Overview

The IS25LQ080-JVLE is an 8Mbit NOR Flash memory IC featuring SPI and Quad I/O interface capabilities, designed for non-volatile storage applications requiring high-speed data access. This component is packaged in an 8-VVSOP surface mount configuration and operates across an industrial temperature range of -40°C to 105°C.

The IS25LQ080-JVLE has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing designs while meeting current supply chain requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the IS25LQ080-JVLE is determined by the following critical parameters:

Memory Capacity & Organization: The substitute part must provide 8Mbit capacity with 1M x 8 organization to ensure direct functional equivalence in storage applications.

Interface Compatibility: The substitute must support SPI with Quad I/O capability to maintain compatibility with existing firmware and hardware interfaces.

Electrical Specifications: Supply voltage range of 2.3V ~ 3.6V and operating temperature range of -40°C ~ 105°C must be met or exceeded to ensure operation in the same application environment.

Package Compatibility: The 8-VVSOP package footprint is mandatory for direct PCB-level substitution without layout modifications.

Compliance Requirements: RoHS3 compliance and MSL 3 rating must be maintained to satisfy regulatory and manufacturing process requirements.

The IS25LP080D-JVLE meets all these criteria and qualifies as a direct substitute.

Engineering Selection Recommendations

The IS25LP080D-JVLE is the qualified substitute for the discontinued IS25LQ080-JVLE. Both components are manufactured by ISSI and maintain identical memory capacity, organization, voltage specifications, temperature range, and package configuration.

The substitute part offers enhanced performance characteristics including increased clock frequency (133 MHz vs. 104 MHz) and reduced write cycle time (800µs vs. 1ms), while maintaining full backward compatibility with the original part's electrical and mechanical specifications.

The IS25LP080D-JVLE carries Active product status with current inventory availability, ensuring reliable supply chain continuity. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, satisfying regulatory and manufacturing requirements without modification to assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the IS25LP080D-JVLE be used as a direct replacement for the IS25LQ080-JVLE?

A: Yes. Both parts share identical memory capacity (8Mbit), organization (1M x 8), interface support (SPI - Quad I/O), voltage range (2.3V ~ 3.6V), temperature range (-40°C ~ 105°C), and package type (8-VVSOP). The substitute part is electrically and mechanically compatible without design modifications.

Q: What are the differences between these two parts?

A: The IS25LP080D-JVLE provides enhanced performance with 133 MHz clock frequency compared to 104 MHz, and 800µs write cycle time versus 1ms. The substitute also supports additional interface modes (QPI and DTR) not present in the original part. These enhancements are backward compatible and do not affect substitution eligibility.

Q: Are there any package or footprint differences?

A: No. Both parts use the 8-VVSOP package with identical 8-SOIC footprint dimensions (0.154" width, 3.90mm). No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the IS25LQ080-JVLE and IS25LP080D-JVLE are ROHS3 compliant with MSL 3 rating (168 Hours). Manufacturing and assembly processes remain unchanged.

Q: What is the availability status of the substitute part?

A: The IS25LP080D-JVLE maintains Active product status with current inventory availability, providing reliable supply chain access compared to the discontinued original part.
