OV5640 connector OV2640: High resolution CMOS chips replace the tide to accelerate the industrial chain reconstruction
First, technology substitution advantages to establish market dominance
1, pixels and performance leapfrog upgrade
The OV5640 uses a 1/4 inch BSI backlit sensor with a resolution of 5 million pixels (2592×1944), which is 150% higher than the discontinued OV2640 (2 million pixels), and supports up to 15fps full-resolution output and 90fps VGA mode. To meet the rigid demand for high-definition picture quality in security monitoring, industrial testing and other fields 35. Its built-in ISP module supports automatic exposure (AEC), automatic white balance (AWB) and other algorithms, which significantly reduces the secondary development cost of downstream manufacturers .
2. indicates the alternative path
OV5640 continues DVP parallel interface design, hardware pin layout is highly compatible with OV2640, only need to adjust the PCB supply voltage (2.6-3.0V) and filter circuit to achieve in-situ replacement, the adaptation period is shortened by more than 60% . Some manufacturers rebuild signal processing modules through domestic protocol stacks such as TurMass™ to further reduce the dependence on the original ecology .
Second, market response and industrial chain synergies
1, surging demand for automobiles and consumer electronics
In BYD's 2025 intelligent driving model plan, 60%-70% of models will be equipped with camera modules supporting high-speed NOA, OV5640 has become the mainstream choice with high dynamic range (HDR) imaging capability, and the number of cameras configured for a single model has increased to 8-12 . In the field of consumer electronics, AI glasses manufacturers use OV5640 to achieve 10 million pixel dynamic shooting function, promoting the purchase price of a single chip to 12-15 US dollars .
2, the penetration of domestic alternatives accelerated
By optimizing the SCCB bus protocol (two-wire I²C) and register configuration process, we help smes realize seamless switching from OV2640 to OV5640, and reduce the comprehensive transformation cost by 30%-40%. The TK8620 chip integrates the TurMass™ communication protocol to form a comprehensive alternative to LoRa solutions in the Internet of Things, with shipments expected to exceed 20 million in 2025 .
Third, industrial chain restructuring and challenges
1, module design complexity increased
The 720p@90fps mode of OV5640 needs to be equipped with high-performance main control chips such as STM32H7, but some manufacturers are limited by the memory capacity (such as STM32H750 only 1MB SRAM), it is difficult to directly process the full-resolution data stream, and need to reduce the load by external FPGA or image compression algorithm.
2. power consumption and cost game
Although the OV5640 outdoes the OV2640 in signal to noise ratio (SNR) in low-light environments, its typical power consumption (280mW) is 45% higher than its predecessor, forcing manufacturers of drones and wearables to redesign their power management systems . Although domestic substitution can reduce the procurement cost, the preliminary verification cost still accounts for 20%-30% of the total project investment .
Fourth, future trend: intelligent and domestic two-wheel drive
1, intelligent driving creates high-level demand
Byd, WEilai and other car companies to promote the popularity of 8MP CIS in the vehicle scene, OV5640 through LOFIC (horizontal overflow integrated capacitance) technology to improve the dynamic range, is gradually replacing ON the AR0130 and other traditional solutions, 2025 vehicle market share is expected to exceed 25%.
2. the acceleration of domestic technology iteration
Weil stock launched OV50H/50K series chips, integrated AI noise reduction algorithm on the basis of LOFIC architecture, directly against SONY IMX586, is expected to achieve 30% of the high-end market share of Android camp in 2026 to replace . The simultaneous development of domestic communication protocols such as TurMass™ and Starflash will further weaken the technical barriers of international standards such as LoRa .
conclusion : OV5640 is rapidly filling the market gap after the OV2640 discontinuation with its performance advantages and mature domestic alternatives. Driven by the demand for intelligent driving and AI equipment, global shipments are expected to reach 120 million in 2025, which will accelerate the evolution of the CMOS sensor industry to high integration and low power consumption.
