P8620-R0NLGI

Overview

The P8620-R0NLGI is a multi-channel power management integrated circuit (PMIC) based on the Cortex-M0 core, designed for Intel industrial System-on-Chip (SoC) platforms. It complies with Intel VR 13.0 specifications and integrates five distributed power device (DPU) controllers supporting up to four P810DPU units. The device features four internal buck regulators, three LDOs, two 10-bit ADCs, and sixteen programmable GPIOs. Operating within a voltage range of 4.2V to 5.5V, it supports high-speed SPI and I2C interfaces. Packaged in a 9x9 mm 64-QFN, it enables precise power sequencing, current measurement, and system diagnostics for industrial applications.

Feature Summary

• Integrates five independent DPU controllers for managing external power stages with pulse load capabilities up to 29A per rail.
• Includes four internal buck regulators and three LDOs with independently configurable output voltages and power-up/down sequences.
• Features built-in safety and diagnostic functions, including DC/DC output current measurement and fault analysis reporting via interrupt controllers.

Applications

• Intel Tiger Lake UP3 / Corner Stone Ridge customer reference boards
• Intel Tiger Lake H / Whale Mountain customer reference boards
• Industrial SoC power distribution systems requiring VR 13.0 compliance

Procurement Notes

Verify firmware compatibility before integration, as the P8620's functionality is defined by internal Cortex-M0 code. Confirm that the specific firmware option matches your platform's implementation requirements. Check official documentation for pin mapping variations across different firmware releases. Ensure supply chain sources provide valid revision history. Validate thermal performance within the -40°C to +85°C operating range during final design review.

Selection Notes

Select this PMIC when designing for Intel industrial SoCs requiring high integration and VR 13.0 compliance. It is suitable for systems needing flexible power sequencing and detailed diagnostic feedback. Consider its 64-QFN package for space-constrained motherboards. Evaluate the need for external DPUs if peak currents exceed internal regulator limits. Ensure software development resources are available for configuring the embedded firmware options.

Part Context

The P8620 belongs to Renesas' portfolio of programmable power management solutions tailored for complex computing architectures. It addresses the growing demand for efficient, compact power delivery in industrial edge computing environments. By combining regulation, sequencing, and monitoring in a single IC, it reduces bill-of-materials complexity compared to discrete solutions.
