EEC1005-I/WC-UB1

Application Specific Microcontrollers Overview

The EEC1005 is a Universal Storage Backplane Management Processor designed for enterprise storage enclosures. It implements the SFF-TA-1005 UBM specification over I2C, supporting SFF-8654 Host Facing Connectors (HFC) and SFF-8639/U.3 Drive Facing Connectors (DFC). The device manages up to 16 SAS/SATA drives via SGPIO or up to 12 NVMe drives via UBM interfaces. It integrates hardware-accelerated cryptography including AES-256, ECDSA P-256, SHA-256, RSA, and TRNG for secure boot and firmware updates. Configuration is determined by an analog voltage on the CONFIG_PIN at startup.

Application Specific Microcontrollers Feature Summary

Supports SFF-TA-1005 UBM over I2C and SFF-8485 SGPIO legacy interfaces
Hardware-accelerated security with AES-256, ECDSA, SHA-256, RSA, and TRNG
Configurable support for up to 16 SAS/SATA or 12 NVMe drives
Integrated NVRAM for UBM FRU, General Purpose FRU, and configuration memory

Application Specific Microcontrollers Applications

Enterprise storage backplanes managing SAS/SATA/NVMe drives
Multi-chassis storage enclosure management systems
Direct attach or host attach backplane architectures

Application Specific Microcontrollers Procurement Notes

Verify the specific package variant required, as the EEC1005 is available in 84-pin and 144-pin WFBGA packages. Confirm that the ordering suffix corresponds to the desired pinout and configuration ID defined in the datasheet tables. Ensure compatibility with the target chassis environment regarding RoHS compliance standards.

Application Specific Microcontrollers Selection Notes

Select the package based on the required drive count and interface type. The 84-pin package supports configurations up to 8 drives, while the 144-pin package supports up to 16 drives or full-feature UBM implementations. Use the CONFIG_PIN resistor divider network to set the specific backplane architecture at startup, as runtime modification is not supported.

Application Specific Microcontrollers Part Context

The EEC1005 serves as a generic, configurable processor for storage backplanes. It bridges the gap between computing hosts and storage devices using industry-standard protocols. It replaces discrete management controllers by integrating UBM logic, LED management, and FRU storage into a single component.
