EEC1005-I/WC-UB2-TR

Application Specific Microcontrollers Overview

The EEC1005-I/WC-UB2-TR is a specialized Universal Backplane Management (UBM) processor from Microchip Technology, designed for enterprise storage enclosure management. It supports SFF-TA-1005 revisions 1.3 and 1.4 over I2C and integrates UBM FRU non-volatile memory. The device features up to eight I2C ports for UBM and BMC interfaces, hardware-accelerated SGPIO legacy interfaces, and secure boot capabilities using ECC P-256. It manages SAS/SATA/NVMe drives via Host Facing Connectors (HFCs) and Drive Facing Connectors (DFCs), supporting configurations for up to 16 drives. The component operates within a voltage range of 3.135 V to 3.465 V and includes integrated NV Memory for configuration and general-purpose FRUs.

Application Specific Microcontrollers Feature Summary

• Supports SFF-TA-1005 Rev 1.3/1.4 UBM over I2C with Intel VPP and EDSFF drive type support
• Integrates hardware-accelerated crypto blocks for secure boot (AES-256, ECDSA P-256, SHA-256)
• Configurable via single analog pin for up to 21 distinct backplane architectures
• Manages up to 16 SAS/SATA or 12 NVMe drives with IBPI LED control

Application Specific Microcontrollers Applications

• Enterprise storage backplane management for SAS/SATA/NVMe enclosures
• Host attach or direct attach backplane architectures with BMC integration
• Multi-chassis storage systems requiring scalable UBM controller solutions

Application Specific Microcontrollers Procurement Notes

Verify the -TR suffix indicates tape-and-reel packaging when sourcing. Confirm the UB2 designation ensures compatibility with SFF-TA-1005 Revision 1.4 and Intel VPP requirements. Check for specific RoHS compliance documentation as indicated in distributor listings. Ensure the ordering part number matches the exact WFBGA-144 package variant required for the design.

Application Specific Microcontrollers Selection Notes

Select the EEC1005-I/WC-UB2-TR for designs requiring SFF-TA-1005 Revision 1.4 compliance or Intel VPP support, which are exclusive to the UB2 family member. Choose this part over the UB1 variant if EDSFF drive types or NVMe x2/x1 U.3 support are needed. Verify that the analog configuration resistor network aligns with the desired HFC and DFC count from the official configuration table.

Application Specific Microcontrollers Part Context

This component belongs to the EEC1005 family of True Universal Backplane Management devices. The UB2 suffix distinguishes it from the original UB1 version by adding support for newer specifications like SFF-TA-1005 Rev 1.4 and enhanced drive interface options. It serves as a generic, configurable solution for managing hard drive backplanes in computing host systems.

Application Specific Microcontrollers Replacement Considerations

The EEC1005-I/WC-UB1-TR is the previous generation counterpart but lacks SFF-TA-1005 Rev 1.4, Intel VPP, and EDSFF support. Direct substitution requires verifying that the target system does not rely on UB2-specific features such as NVMe x2/x1 U.3 connectivity or specific VPP addressing modes.
