GL9750
產品簡述
GL9750 is a PCI Express Rev. 1.1 compliant card reader controller which integrates PCI Express PHY, memory card access interface, regulators (3.3V-to-1.2V) and card power switch.
GL9750 supports various types of SD memory cards, such as Secure DigitalTM (SD), SDHC, miniSD and microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro and MMCmobile. It also supports high density memory cards (Capacity up to 2TB), such as SDXC, ultra high speed memory cards, SD 3.0 UHS-I.
GL9750 supports PCI Express L1 PM sub-states, Runtime D3 (RTD3), Latency Tolerance Reporting (LTR), and Optimized Buffer Flush/Fill (OBFF) for saving power consumption.
