Page 15: Ftdi Serial To Usb Interface
GR716-MINI FTDI Serial to USB Interface The GR716-MINI board provides an FTDI FT4232HL Serial to USB interface chip which provides up to 4 serial ports which connect to a single Micro-B USB connector (J1). This USB port can be connected to a host computer to allow communication over serial interfaces to Host PC's which do not have conventional 9 pin D-sub type RS232 connectors. -
Page 16: Analog Signals
GR716-MINI Analog Signals The GR716-MINI board provides four micro-miniature (MMCX) coaxial connectors to allow access to up to 4 ADC inputs or 4 DAC outputs of the GR716 microcontroller. As shown in Figure 4-11, depending on which resistors are installed, each MMCX connector can be either an ADC input or a DAC output. -

Page 19: Debug Support Unit Interfaces
Program download and debugging to the processor is performed using the GRMON Debug Monitor tool from Frontgrade Gaisler ([RD4]). The GR716 microcontroller provides a UART based DSU interface for Debug and control of the processor by means of a host terminal, as represented in Figure 4-11. -
Page 20: Oscillators And Clock Inputs
GR716-MINI 4.12 Oscillators and Clock Inputs The oscillator and clock scheme for the GR716-MINI Board is shown in Figure 4-12. Two oscillator inputs are required: CLK for the main system clock, and SPW_CLK for the SpaceWire clock of the microcontroller. -
Page 21: Power Supply And Voltage Regulation
LMZ21701 micro Point-of-Load regulator is included on the board which generates the 3.3V for the rest of the GR716-MINI board. In an alternative scenario, when the GR716-MINI board is installed on an Expansion board or Motherboard, it is intended that the Motherboard should generate a regulated 3.3V supply and provide this via the Expansion connector. -
