The OS85621 device belongs to Microchip’s family of I/O Companions (IOCs) and is specifically designed for use in video applications.
For ultra-low latency applications, such as camera modules for driver assistance systems, the OS85621 video companion device supports special H.264 encoding/decoding of I-Frames only.
For applications requiring higher compression, the OS85621 device also provides a DDR2 SDRAM interface to which external memory can be made available for supporting I/P-Frame encoding/decoding.
The integrated DTCP coprocessor supports full Authentication Key Exchange (AKE), as well as multiple channels for M6 or AES-128 encryption/decryption of audio and video data streams. The device’s Private Key can be stored in non-readable One-Time Programmable (OTP) memory, eliminating security risks associated with key transmission by the application. To ensure compatibility with other DTCP devices and further reduce development efforts, Microchip also offers its free and ready-to-use DTCP-Stack for I/O Companions.
Using an OS85621 device, audio and video data can be routed on/off a network via a MediaLB Port connected to one of Microchip’s Intelligent Network Interface Controllers (INICs). The audio and video exchange at the hardware ports may be either synchronous or asynchronous to the network frame rate.
If DTCP is not required, please consider OS85623.
