Product details
Overview
PM8270B-F3EI from Microchip Technology is a SmartIOC 2200 PCIe Gen 4 tri-mode I/O controller supporting 16-lane host interface and 16 tri-mode storage lanes (NVMe/SAS-4/SATA), with no hardware encryption, 16-bit DDR4 memory interface, and housed in a 31 mm × 31 mm package. It enables high-performance, secure server storage connectivity in native HBA, basic RAID 0/1/10/5, or transparent NVMe modes.
For engineers reviewing the PM8270B-F3EI datasheet, PM8270B-F3EI pinout, PM8270B-F3EI application, or PM8270B-F3EI equivalent, key selection criteria include PCIe Gen 4 ×16 host bandwidth, SAS-4 24 Gbps PHY support per lane, Dynamic Channel Multiplexing for SAS/SATA aggregation, hardware root-of-trust with Secure Boot, and compatibility with maxView™ and ARCCONF management tools across Linux, Windows, and UEFI environments.
Technical Context
The PM8270B-F3EI integrates a Switchtec-based PCIe Gen 4 switch with ×1 to ×8 bifurcation capability and supports non-transparent bridging with address translation. It implements Universal Backplane Management (UBM) for automatic PCIe/SAS/SATA detection and per-drive mode selection (RAID/HBA/transparent).
It delivers SAS-4 PHYs operating at 24 Gbps with Dynamic Channel Multiplexing (DCM) enabling near-100% bandwidth efficiency for legacy SAS/SATA drives over SAS-4 links, and includes PCIe error containment features including downstream port containment and poisoned TLP blocking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar tri-mode storage controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PM8274B-F3EI | Same 16×32 lane configuration but adds hardware AES-XTS encryption engine and supports up to 32 storage lanes | Required where IEEE 1619-compliant data-at-rest encryption is mandated for SAS/NVMe media | Select PM8274B-F3EI when encryption is required; PM8270B-F3EI is optimal for cost-sensitive, non-encrypted deployments |
| PM8262B-F3EI | 8×16 lane configuration (8 host / 16 storage), same no-encryption feature set, smaller 25 mm × 25 mm package | Suitable for space-constrained 1U servers or embedded storage controllers with lower lane count needs | Choose PM8262B-F3EI for reduced footprint and lower power; PM8270B-F3EI provides full ×16 host bandwidth and higher aggregate throughput |
Compared with PM8274B-F3EI, PM8270B-F3EI trades hardware encryption for lower cost and power, while versus PM8262B-F3EI it delivers double the host PCIe lanes and higher storage density-making it ideal for full-featured 2U+ enterprise servers needing maximum I/O flexibility without encryption overhead.

FAQ
What is the PCIe generation and lane count supported by the PM8270B-F3EI?
The PM8270B-F3EI supports PCIe Gen 4 with a ×16 host interface, delivering up to 32 GBps bidirectional bandwidth. It also supports flexible bifurcation down to ×1, allowing compatibility with a wide range of NVMe SSD configurations. This full-width interface ensures minimal latency between CPU and storage resources in high-throughput server environments. The PM8270B-F3EI maintains backward compatibility with PCIe Gen 3 and Gen 2 hosts through automatic speed negotiation.
Does the PM8270B-F3EI include hardware encryption capabilities?
No, the PM8270B-F3EI does not integrate a hardware AES-XTS encryption engine. It is the non-encrypted variant in the SmartIOC 2200 family. For deployments requiring IEEE 1619-compliant data-at-rest encryption, Microchip offers the PM8274B-F3EI or PM8271B-F3EI as alternatives. The PM8270B-F3EI relies on host-based or software-defined encryption stacks when confidentiality is required.
What memory interface does the PM8270B-F3EI use, and what is its purpose?
The PM8270B-F3EI features a 16-bit DDR4 memory interface used to connect external DRAM for storing command descriptors, I/O queue structures, RAID metadata, and device management tables. This off-chip memory is essential for sustaining high IOPS and supporting cacheless RAID operations. The PM8270B-F3EI does not include embedded SRAM for these functions, making DDR4 integration mandatory in system design.
How does Dynamic Channel Multiplexing (DCM) function on the PM8270B-F3EI?
Dynamic Channel Multiplexing (DCM) on the PM8270B-F3EI aggregates bandwidth from multiple lower-speed SAS or SATA drives onto a single 24 Gbps SAS-4 link-achieving up to 98% utilization efficiency. It operates transparently at the PHY layer without host or driver involvement. DCM allows cost-effective deployment of legacy drives in modern SAS-4 infrastructures, and is fully supported when paired with Microchip's SXP 24G SAS-4 expanders.
Which management tools are compatible with the PM8270B-F3EI?
The PM8270B-F3EI is supported by Microchip's unified Smart Storage software suite, including the maxView™ web-based GUI, ARCCONF command-line interface, UEFI pre-boot utilities, and third-party plugins for VMware vSphere and OpenStack. All tools provide consistent visibility and control across mixed NVMe/SAS/SATA topologies. Drivers and firmware updates for the PM8270B-F3EI are validated for Windows Server, RHEL, SLES, and Ubuntu LTS distributions.
