Industrial Memory Flash IC eMMC 256GB 128GB 64GB for Network and Communication Equipment 5G Base Stations
eMMC is a storage chip that integrates NAND Flash memory and flash controller into a standard BGA package. It connects to the main processor through a standard interface, simplifying design complexity. Compared with consumer-grade eMMC, industrial-grade eMMC adheres to stricter standards for temperature range, reliability, lifespan, and quality control.

Core Applications of Industrial Memory Flash IC eMMC in 5G Base Stations
5G base stations (including AAU and DU) operate in demanding deployment environments that require the highest levels of reliability.
Baseband Processing Unit Software Storage
Application: Storage of physical layer and link layer processing software with extremely high real-time requirements. These software components handle wireless signal encoding, modulation, scheduling, and related functions.
Function: Industrial eMMC serves as startup and operational storage for the main processor on the baseband board. Any software error can directly cause abnormal RF signals, affecting call quality and internet connectivity for large user areas.
Industrial Requirements: Base stations deployed on rooftops and towers experience internal chassis temperatures exceeding 70°C in summer, with additional lightning surge risks. A wide temperature range of -40°C to +85°C and high anti-interference capability are essential.
Operation and Maintenance Management Data Storage
Application: Storage of performance measurement reports, alarm information, key counters, and wireless parameter configurations for base stations.
Function: When transmission links are interrupted, industrial eMMC reliably stores operational data locally and uploads it to network management centers after connection restoration, providing critical data for network optimization and fault diagnosis.
Industrial Requirements: Operational data forms the foundation for analyzing network quality and resolving user complaints. Storage media must withstand harsh outdoor conditions including high temperature, high humidity, and temperature cycling.
Self-Organizing Network Functional Storage
Application: Supports 5G SON (Self-Organizing Network) functions, storing neighbor relationships, self-optimizing algorithm parameters, and related data.
Function: Provides stable parameter storage space for distributed intelligent functions that enable network automation.
Industrial Requirements: The reliable operation of SON functions is fundamental to network automatic optimization. Parameter reliability directly impacts overall network performance.
