The two new products have memory in-package to offer a small package size of 15mm x 15mm, thus making it ideal to record, play and transmit superior picture quality HD video on portable devices such as digital camcorders, as well as on home networked appliances, commercial broadcast equipment, and security cameras.

For digital camcorders, the H.264 compression format has become mainstream, providing longer recording times than the previous MPEG-2 compression format. At the same time, longer battery life is essential to increase the length of time you can continuously record or play on one battery charge. However, with the ever-shrinking size of digital camcorders, large batteries can’t be used, thus making low power consumption of the internal components a key requirement.

Since 2007, Fujitsu Microelectronics has been providing its MB86H51, which is a Full HD H.264 CODEC featuring in-package memory. The new low power MB86H55 has a power consumption of only 500mW during Full HD encoding, including the in-package memory power consumption. This allows an extension in the length of time one can continuously record and play HD video on digital camcorders and other portable devices while maintaining superior picture quality.

The other new CODEC LSI, MB86H56, continues the reputation for high picture quality of the existing MB86H51, by even further increasing the picture quality with processing at 60 frames per second (progressive).

These two new products, as well as the existing MB86H51 CODEC LSI, utilize Fujitsu Laboratories’ proprietary picture quality algorithm to realize superior picture quality and a reduced video processing burden enabled by high-compression technology. Leveraging Fujitsu’s highly regarded expertise in image processing-related technologies and products, Fujitsu Microelectronics will continue to strengthen its imaging and video processing ASSPs.

Key Features

1. Small form-factor, low power consumption necessary for portable devices
   Both new products contain one 512M bit memory (FCRAM⁽³⁾) in-package. Due to the reduction in the number of memory chips, as well as the usage of 65nm process technology, the power consumption during Full HD encoding, including the in-package memory, is reduced to 500mW (at 30 frames per second). Also, it is provided in a small form-factor, 15mm x 15mm package.
2. Processing at 60 frames/second (progressive) further improves picture quality (MB86H56)
   The existing CODEC product, MB86H51, processes video at 30 frames per second; while the new MB86H56 doubles this to 60 frames per second (progressive), 60p, to boost picture quality.
3. Both LSIs feature embedded scaler for picture expansion/reduction
   Both products have an embedded scaler for expansion or reduction of the picture. In units of 16 bit x 32 lines, pictures can be expand by a maximum of 6 times or reduced to 1/6, therefore enabling flexible accommodation of the requirements for picture quality, resolution, and bit rate depending on the application.
4. Improved connectivity to peripheral LSIs
   Both products contain many interfaces for improved connectivity. For the host interface to connect to an external CPU, there is a 16 bit parallel interface and a TS interface as the video stream interface. In addition, there is a serial interface in which a reduction of pins for host interface is possible, as well as a PCI interface for connecting a PC or a recorder. Connection to external ROM is also possible, thus realizing high-speed boot for devices that feature this LSI.

Glossary and Notes

1 H.264:

A video compression standard defined by the International Telecommunication Union, Telecommunication Standardization Sector (ITU-T). A video-encoding format noted for offering more compression than MPEG-2 and other earlier formats. The International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) has defined the MPEG-4 Part 10 Advanced Video Coding (MPEG-4 AVC), however it is the same as H.264.

2 60 frames/sec (progressive) processing:

Referred to as “60p”. Every second, 60 video frames are processed, by all the lines in the frame being processed in sequence (progressive). This creates higher picture quality than so called “60i” where odd lines and even lines are drawn alternately (interlace), such that 30 frames per second processing appears like 60 frames.

3 FCRAM (Fast Cycle RAM):

Fujitsu Microelectronics’ proprietary RAM core architecture featuring high-speed and low power consumption.
