PM8262B-F3EI

Overview

The Microchip Technology PM8262B-F3EI is a SmartIOC 2200 storage controller featuring an 8 × 16 lane configuration with no integrated host or disk encryption. It utilizes a 25 mm × 25 mm package and supports up to 16-lane PCIe Gen 4 connectivity to the host. The device provides up to 32 tri-mode storage lanes, enabling NVMe, SAS-4, and SATA media support. Key capabilities include Dynamic Channel Multiplexing (DCM) for bandwidth aggregation, hardware root-of-trust for Secure Boot, and basic RAID levels 0, 1, 10, and 5.

Feature Summary

• Supports automatic detection and link speed negotiation for PCIe, SAS, and SATA via Universal Backplane Management.
• Integrates Switchtec technology for low-latency NVMe connectivity with flexible port bifurcation down to x1.
• Provides hardware root-of-trust with firmware signing for Secure Boot and Secure Update.
• Enables near 100% efficient bandwidth aggregation for lower-speed drives over SAS-4 links using Dynamic Channel Multiplexing.

Applications

• Enterprise server storage architectures requiring mixed NVMe and SAS topologies.
• Dense cloud storage environments utilizing SFF-TA-1001 tri-mode drives.
• Hyperscale servers needing high-performance IO aggregation with DCM.
• Systems requiring secure boot and data-at-rest encryption foundations.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm packaging dimensions and encryption status. Ensure compatibility with the target server's PCIe generation and backplane specifications before procurement. Cross-reference the part number with authorized distributors to confirm authenticity and availability of necessary management software drivers.

Selection Notes

Select this model for configurations requiring eight host lanes and sixteen disk lanes without built-in encryption. Compare against the PM8274B-F3EI if thirty-two disk lanes are required instead of sixteen. Consider the PM8263B-F3EI variant if hardware-based disk encryption features are necessary for the deployment environment.

Part Context

This component belongs to the SmartIOC 2200 family, which serves as a versatile tri-mode storage connectivity solution. The family integrates advanced manageability and security features designed for next-generation data centers. It complements other controllers like the SmartROC 3200 by providing robust IO handling for NVMe, SAS-4, and SATA media.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate the PM8252B-F3EI for reduced lane counts or the PM8263B-F3EI for identical functionality with added encryption capabilities.
