of the USB ports are brought to standard Type A connectors (J6 – Dual host port connector and J25 – Single host port). The
forth USB is routed to PCIe Mini-Card #1 (J28).
2.9 Storage
There are two SD/MMC sockets on the Tegra 200 Series Developer Board. Both sockets support High Speed operation
(52MHz for MMC, 50MHz for SD/SDIO)
SD/MMC Socket 1 (J26)
The J26 SD/MMC socket is a combination 8-bit MMC and 4-bit SD/MMC socket intended to be for internal storage, most likely
an eMMC module. Although this device is in a socket, it is not meant to be used as removable storage in a real design. 3.3V is
supplied to the socket. There is also a 2-pin header (J5) to supply a core rail at 2.85V. This header is used when the eMMC
module is installed in this socket.
SD/MMC Socket 2 (J5)
The J5 SD/MMC Socket is a removable storage is a standard 4-bit SD/MMC socket. This would normally be located to allow
SD/MMC/SDIO cards to be inserted and removed by the user. 3.3V is supplied to this socket.
2.10 Camera (optional)
A socket for a camera module is provided on the Tegra 200 Series Developer Board (J9).
2.11 Wireless
Bluetooth and Wifi
The Tegra 200 Series Developer Board integrates a MuRata BT/WF Module using the CSR-BC6 and Atheros AR6002
controllers.
The Bluetooth 2.0 transceiver sends and receives on a 2.4GHz line, including Enhanced Data Rates (EDR) up to 3Mbps and
scatter-net support. USB and Dual UART Ports with rates up to 3MBaud are supported. It operates at full speed Bluetooth
operation with full piconet support and co-exists with 802.11. The CSR device will act as a serial peripheral when connected to
the Tegra 250 via a serial port. This interface, as with WiFi below, will be implemented on a substrate (typically LTCC) supplied
by MuRata containing all components required for operation, to minimize tuning and testing. An external antenna for 2.4GHz
(available off the shelf) is also required
The 802.11b/g transceiver sends and receives on a 2.4GHz line at 54Mbps max. It provides full QoS for 802.11e and security
support 802.11i and co-exists with the Bluetooth device. The interface of choice is SDIO. This interface will be implemented on
a LTCC substrate supplied by MuRata and soldered down to our board to minimize tuning and testing.
An external antenna supporting both Bluetooth and WiFi for 2.4GHz (available off the shelf) is required and available from a
variety of suppliers.
PCIe Mini-Card (3G Modem support and more)
The Tegra 200 Series Developer Board provides two PCIe Mini-Card slots. Both slots support PCIe operation as well as USB
2.0 High Speed. Slot #0 (J27) also routes to a UIM SIM socket (J19) and is intended to support compatible 3G Modem
modules. PCIe Mini-Card slot #1 (J28) could be used for other peripherals such as Solid-State drives or a different WiFi
solution.
