Introduction[edit | edit source]

This chapter contains the pinout description of 204-pin DDR3 SODIMM edge connector of Maya module. Each row in the pinout table contains the following information:

  • Pin: reference to the connector pin
  • Pin Name: pin (signal) name on the Naon connectors
  • Internal connections: connections to the Naon components
    • CPU.<x> : pin connected to CPU pad named <x>
    • KEY.<x>: pin connected to the keypad controller
    • TSC.<x> : pin connected to the touchscreen controller
    • EEPROM.<x> : pin connected to the EEPROM
    • CAN.<x> : pin connected to the CAN transceiver
    • PMIC.<x> : pin connected to the Power Manager IC
    • LAN.<x> : pin connected to the LAN PHY
    • USB.<x> : pin connected to the USB transceiver
    • SV.<x>: pin connected to voltage supervisor
    • MTR: pin connected to voltage monitors
  • Ball/pin #: Component ball/pin number connected to signal
  • Supply Group: Power Supply Group
  • Type: pin type
    • I = Input
    • O = Output
    • D = Differential
    • Z = High impedance
    • S = Power supply voltage
    • G = Ground
    • A = Analog signal
    • Voltage: I/O voltage levels

The Internal connection column reports the name of the microprocessor signal, which in turn contains references to all the peripheral functions that can be associated to that pin. For example, the following pin name CPU.VOUT[1]_B_CB_C[4]/EMAC[1]_MRXD[0]/VIN[1]A_D[1]/UART4_RXD/GP3[1] means that the pin can be used as:

  • VOUT[1]_B_CB_C[4]: Video output data, port 1, B/CB/C color bit 4
  • EMAC[1]_MRXD[0]: Ethernet MAC, port 1, [G]MII Receive Data, bit 0
  • VIN[1]A_D[1]: Video input channel 1, port A data input bit 1
  • UART[4]_RXD: UART port 4, receive data input
  • GP3[1]: General Purpose I/O port 3, channel 1

The following table reports all the function names that can be found on the Internal connection and the associated description.

Function name Description
VOUT[x] Digital video output. “x” represents the port number (0 or 1).
VIN[x]A/B Digital video input. “x” represents the capture number (0 or 1). Each capture has two ports (A and B)
EMAC[x] Ethernet MAC. “x” represents the port number (0 or 1)
UART[x] UART port. “x” represents the port number (0 to 5)
GPx[y] General Purpose I/O port. “x” represents the port number (0 to 3)
CAM Camera Interface
SPI[x] SPI channel. “x” represents the channel number (0 to 3)
DCAN[x] Controller Area Network module. “x” represents the module number (0 to 1)
HDMI High-Definition Multimedia Interface
SD[x] MMC/SD/SDIO interfaces. “x” represents the interface number (0 to 2)
GPMC General Purpose Memory Controller (local bus)
MD Management Data I/O module
MCA[x] Multi-Channel Audio Serial Port (McASP). “x” represents the port number (0 to 5)
I2C[x] I2C channel. “x” represents the channel number (0 to 3)
AUD Audio Reference Clock
TIMx General purpose timer. “x” represents the terminal number (0 to 7)

Additional notes[edit | edit source]

(1) Some pins support multiple routing options. Selected option is populated at manufacturing stage and can not be changed at later time.
