Genesys Logic Announces Industry’s First PCI Express to SD 8.0 Memory Card Reader Controller Support SD 4.0 UHS-II Speed Mode – GL9767

Genesys Logic, Inc., a leading IC design company in mixed-signal, high-speed I/O technologies, today announced GL9767, its high-performance SD Express memory card reader controller.

GL9767 is a PCI Express to SD Express card reader controller. The major applications are the internal SD Express card reader of laptop, mini PC, Server system, professional camera, game console and drone devices that demand the high speed of the SD storage or the second SSD-like storage for the real memory expansion.

GL9767 support 1-Lane 2.5 / 5.0 / 8.0 GT/s PCI Express bus connect to the PCI Express host. The support of SD Express interface can be up to SD 8.0 SD Express (PCIe Gen.3 x 2) by a specific system design and the bandwidth is 1970 MB/s. GL9767 also support SD 7.1 SD Express (PCIe Gen. 3 x 1) and the bandwidth is 985 MB/s. GL9767 can work with the new SDUC card featuring capacities of up to 128 TB.

GL9767 is the first SD Express card reader controller which can backward support SD 4.0 UHS-II speed mode. The existing devices support UHS-II card slot use GL9767 in the next generation product not only upgrade the speed of SD storage also retain the fully support of UHS-II card. GL9767 also support SanDisk high-performance UHS-I card up to 200 MB/s of reading speed.

For power saving, GL9767 support PCI Express ASPM, L1 sub-states (L1.1 and L1.2) and RTD3 (Runtime D3 Hot/Cold), Modern Standby and S0ix.

Availability and Pricing
GL9767 will be entering mass production in the second quarter of 2023. The design kit and the IC sample are available now. Fore more information availability and pricing please visit email:
