WM8310CGEB/V

Overview

The WM8310CGEB/V is a discontinued processor power management subsystem integrated circuit manufactured by Cirrus Logic Inc. It functions as a comprehensive Power Management Integrated Circuit (PMIC) designed to handle multiple voltage regulation and system control tasks for complex processors. The component is housed in a 169-ball Fine-Pitch Ball Grid Array (FBGA) package, identified by the suffix V. This device integrates buck regulators and other power management features essential for portable electronic applications requiring efficient power distribution.

Feature Summary

• Integrates multiple power management functions within a single processor subsystem
• Includes buck regulator capabilities for efficient voltage conversion
• Designed for compact form factors using a high-density ball grid array package

Applications

• Portable electronic devices requiring integrated power management
• Processor systems needing multi-rail power distribution
• Embedded applications utilizing Cirrus Logic PMIC solutions

Procurement Notes

This component has been officially declared End-of-Life (EOL) by Cirrus Logic due to product maturity and limited demand. The final order date was April 29, 2019. Procurement is restricted to existing surplus stock from third-party distributors or secondary markets. Verify authenticity and storage history carefully, as standard manufacturing support and new production are no longer available.

Selection Notes

Due to the EOL status, this part is unsuitable for new design-in projects requiring long-term supply chain stability. Engineers should evaluate alternative modern PMICs with active lifecycle support. If replacing existing designs, ensure mechanical compatibility with the 169-ball FBGA footprint and verify that functional requirements match the legacy specifications of the WM8310 series.

Part Context

The WM8310 belongs to the Cirrus Logic WM83xx family of audio and power management ICs. These components were widely used in mobile and handheld devices before being superseded by newer generations. The CGEB variant typically refers to an evaluation board configuration, while the specific part number indicates the packaged IC component itself within that ecosystem.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the discontinuation, engineers must consult current Cirrus Logic catalogs for equivalent modern PMICs that offer similar integration levels and package footprints.
