The SD Gold Host II provides two SD/SDIO slots said to support most types of SD/SDIO cards, including WiFi, Bluetooth, modem, GPS, and LAN adapter SDIO cards. The slots also support SD memory, Jinvani says.

The “production quality” SD/SDIO controller board is capable of 20 Mbps data transfer rates, and enables multiple bus configuration modes. It also supports booting of the system OS directly from SD memory.


SD Gold Host use cases

Key features and specifications, as listed by the company, include:

  • Supports two SD card slots
  • SD memory and SDIO capable
  • SD Host 1.0 compatible
  • Supports high capacity / high speed SD memory cards
  • Supports security commands
  • Supports SD 1-bit and 4-bit modes (no SPI)
  • Supports SD Sleuth II

Additionally, to assist with the process of device driver development, the controller board provides an interface connector that contains its internal address and data bus signals.

Support for Linux and various real-time operating systems (RTOSes) is available via the company's JSMIMC SD bus stack drivers. The board can also be used with native SD PCI drivers built into Windows CE, Windows XP SP2, and Windows Vista SP 1, Jinvani says.

The SD Gold Host II dual-host controller board appears to be immediately available. Pricing was not disclosed.
