As critical components for data storage and retrieval in electronic systems, memory devices are indispensable for stable operation across automotive, industrial, and consumer electronics. ROHM Semiconductor, leveraging advanced semiconductor process technology, offers a focused yet high-performance memory portfolio, centered on EEPROM (Electrically Erasable Programmable Read-Only Memory) and Flash memory. These products deliver industry-leading low power consumption, extreme environmental resilience, and automotive-grade reliability, ensuring secure data storage for mission-critical applications. To secure genuine products, stable inventory, and professional technical support, partnering with ROHM’s authorized distributors is essential. Below is a complete guide to sourcing ROHM memory via trusted channels.

Core Product Lines & Technical Advantages

ROHM’s memory lineup is tailored to diverse data storage needs, with two key product series leading the market in performance for high-reliability and low-power scenarios:

1. EEPROM (Electrically Erasable Programmable ROM)

Optimized for frequent data rewrite and long-term retention, ROHM’s EEPROMs feature I2C/SPI interfaces, low power consumption, and automotive-grade compliance, ideal for storing configuration data and calibration parameters:

  • BR24 Series (I2C Interface EEPROM): A flagship series with AEC-Q200 qualification, covering 1Kbit-128Kbit capacity range. The BR24GxxFVM variant offers ultra-low power consumption (1μA typ. standby current, 50μA active current) and -40℃~125℃ operating temperature, making it perfect for automotive ECUs, BMS, and industrial sensors. With 1 million+ write endurance cycles and 100-year data retention, it ensures stable data storage in harsh environments. Available in compact SOT-23-5/SOP-8 packages, supporting automated assembly and space-constrained designs.

  • BR25 Series (SPI Interface EEPROM): Complementary to the BR24 series, with 1Kbit-64Kbit capacity and SPI communication protocol. The BR25HxxFV-LB variant features 10MHz high-speed SPI, write protection function, and RoHS compliance, suitable for IoT devices, smart meters, and consumer electronics. The compact 8-pin package reduces PCB space by 20% vs. conventional models, enabling miniaturization of portable devices.

2. Flash Memory (NOR Flash)

Engineered for high-speed read operations and large-capacity data storage, ROHM’s NOR Flash memory excels in storing firmware and executable code for industrial and automotive systems:

  • BF25 Series (NOR Flash): AEC-Q200 qualified, with 1Mbit-32Mbit capacity and SPI interface. The BF25QxxFV variant offers 120MHz high-speed read (4x faster than conventional models) and -40℃~125℃ operating temperature, ideal for automotive infotainment systems, industrial control modules, and medical equipment. It supports sector-wise erase and byte-wise program, with 100K+ write endurance cycles and 20-year data retention, ensuring reliable firmware storage.

  • Low-Power NOR Flash (BF25L Series): Optimized for battery-powered devices, with 1Mbit-16Mbit capacity and 0.5μA typ. standby current. The BF25LxxFV variant features deep sleep mode, reducing power consumption by 30% vs. standard Flash memory, making it suitable for IoT sensors, wearable devices, and portable medical equipment.

Key Technological Advantages

  • Automotive-Grade Reliability: AEC-Q200 qualification, -40℃~125℃ operating range, and anti-vibration design meet strict automotive environment requirements, ensuring stable operation in under-hood and chassis-mounted applications.

  • Ultra-Low Power Consumption: Advanced circuit design achieves standby current as low as 0.5μA, extending battery life for IoT, wearable, and battery-powered industrial devices.

  • Long-Term Data Security: 1 million+ write endurance cycles and 100-year data retention for EEPROM, 100K+ cycles and 20-year retention for Flash memory, preventing data loss in long-cycle projects.

  • Versatile Compatibility: I2C/SPI interfaces, compact SMD packages (SOT-23, SOP-8), and RoHS compliance support diverse system integration, adapting to automotive, industrial, and consumer electronics.
