CFX's 55nm BCD process OTP IP has been put on the shelves

May 26, 2025 -- Recently, Zhuhai Chuangfeixin Technology Co., Ltd. announced that its independently developed 55BCD (55nm Bipolar-CMOS-DMOS Generic Process) OTP IP (One-Time Programmable Memory IP Core) has been successfully qualified at a world-leading integrated circuit manufacturer (hereinafter referred to as "the foundry"). This OTP IP has strictly passed three batches of reliability tests in accordance with non-volatile memory certification standards. This achievement marks a significant breakthrough for Chuangfeixin in the IC field, further enhancing its competitiveness in the global semiconductor market.

As China’s leading non-volatile memory IP provider with proprietary intellectual property rights, Zhuhai Chuangfeixin has been committed to technological R&D in circuit design, device optimization, and process integration, holding multiple domestic and international invention patents. The qualification of this 55BCD OTP IP at the foundry demonstrates the culmination of Chuangfeixin’s long-term technological accumulation and innovation.

Technical Highlights

The 55nm BCD process plays a vital role in display drivers, power management, and other applications. The OTP IP delivers value in the following aspects:

1. Display Driver Applications

• Parameter Storage & Calibration: Stores OLED panel brightness calibration parameters for pixel luminance adjustment and uniformity improvement; retains color calibration parameters to ensure accurate and consistent RGB color performance.
• Demura Compensation: Stores compensation data for real-time brightness/color adjustment during panel operation, delivering uniform display quality.
• Driver IC Configuration: Stores configuration parameters (e.g., drive current, voltage, scan frequency) to ensure proper OLED panel driving; enables firmware upgrades by storing new algorithms or functional modules.
• Security & Authentication: Safeguards device identity information (e.g., unique serial numbers, encryption keys) for authentication and firmware upgrade protection against tampering.

2. Power Management Applications

• Configuration Storage: Maintains voltage/current output settings and frequency/phase error coefficients for precise power system control.
• Parameter Calibration: Stores calibration data (e.g., for DC-DC converters) to optimize power conversion efficiency and output accuracy.
• System Protection: Retains protection thresholds (overvoltage/overcurrent/overtemperature) to trigger safety measures when anomalies are detected.

3. Industrial Control Applications

• Equipment Parameter Configuration: Stores controller settings (e.g., motor driver speed/torque, inverter frequency/voltage) for precision industrial control.
• System Calibration: Holds compensation data (e.g., temperature calibration parameters) to correct operational deviations and enhance stability.
• Industrial Security: Stores authentication credentials and encryption keys to prevent cyberattacks in industrial networks.

Advantages of Chuangfeixin’s 55BCD OTP IP

1. High Reliability & Yield

Chuangfeixin’s core team secured OTP-related patents as early as 2013, with deep expertise in anti-fuse OTP technology. The anti-fuse OTP IP employs oxide-layer breakdown programming and requires no process modifications, achieving standard CMOS-comparable yield and reliability. Redundancy design further enhances robustness.

2. Large Capacity Support

With 32KB capacity, the IP accommodates diverse data storage needs for multifunctional applications.

3. Mass-Production Proven

Chuangfeixin’s BCD-platform OTP has been in volume production since 2022, with stable supply and market validation confirming its safety and reliability.
