Zhuhai Chuangfeixin: OTP IP Based on 55nm High-Voltage Process Successfully Qualified for Listing

May 6, 2024 -- Zhuhai Chuangfeixin Technology Co., Ltd. (CFX), a leading provider of Non-Volatile Memory IP (NVM IP) in China, has recently announced the successful qualification of its OTP IP (One-Time Programmable memory IP core) based on the 55nm high-voltage (55HV 1.2V/6V/32V Process) process. This OTP IP has been listed in one of the top three foundries in China after passing rigorous reliability tests across three batches, meeting the non-volatile memory assessment standard set by the foundry and achieving a successful listing. This significant milestone represents CFX’s advancement in offering customers secure and reliable OTP IP solutions tailored for the 55HV process.

“We are pleased with the successful listing of the 55HV process OTP IP in the foundry, which not only demonstrates CFX’s technical prowess in non-volatile memory IP but also delivers tangible value to our partners and customers,” said George Wang, CEO of CFX. “This milestone further enhances our OTP IP product portfolio across critical process nodes, enabling us to provide customers with OTP IP solutions boasting higher reliability, lower costs, and reduced area.”

Advantages of CFX’s 55HV Process OTP IP

• High Reliability and Yield: CFX’s core team secured OTP-related patents in 2013, establishing a strong foundation in anti-fuse OTP IP technology. The technology involves programming through oxide layer breakdown, ensuring high reliability and yield similar to standard CMOS processes. Incorporating redundancy in the design further enhances reliability and yield.
• Wide Voltage Supply and Support: The IP accommodates a wide voltage supply range, enhancing compatibility, application scenarios, and stability.
• Extensive Mass Production Verification: CFX’s HV platform OTP has been mass-produced since 2015, with over 100,000 wafers produced, demonstrating market validation and customer recognition for safety and reliability.

Application of OTP IP in LCD Display Drivers

OTP (One-Time Programmable) IP, a core programmed once, ensures data permanence, preventing alteration or erasure. With the growing use of embedded applications, OTP safeguards hardware designs and secures products against unauthorized access, finding extensive use in display drivers, image sensors, power management chips, MCUs, Bluetooth chips, and other fields.

The OTP IP based on the 55HV (55HV 1.2V/6V/32V Process) process is extensively utilized in the LCD display driver domain, where OTP plays a crucial role in screen calibration and maintaining stable display performance. Screen flickering caused by V-Common voltage offset in the IC can be mitigated using OTP. It eliminates screen flickering by detecting panel brightness performance under different V-Common voltages and recording optimal values in OTP.
