RVI Header
RVI header for application programming and debug from Keil ULINK or IAR J-Link.
Embedded FlashPro5 Embedded FlashPro5 for RTG4 programming and debugging with Microsemi tools.
Future Technology
Devices International
(FTDI) programmer
FTDI programmer interface (J47) to program the external SPI flash. An FTDI chip is also used
to change the JTAG_SEL signal (high or low) remotely for switching between the RVI header
and JTAG mode.
Embedded trace
macro (ETM) cell
header
ETM header for debug.
PCIe edge connector PCI Express edge connector with four lanes.
Light-emitting diodes
(LEDs)
Eight active-low LEDs connected to some of the user I/Os for debugging/ testing.
Push-button reset
Active-low push-button system reset for the RTG4 device.
Push-button and DIP
switches
Four active-low push-button switches and one DIP switch for test and navigation.
FMC connectors
Two FMC connectors to connect the external daughter boards. Connector array socket 400
pins (40 × 10), 1.27 mm pitch. The SerDes pins and unused user MSIO/MSIOD are routed
from the RTG4 device to the J34 and J12 connectors.
Chip
A simple three-pin voltage monitor and power-on reset that holds reset for 150 ms for
stabilization after the power returns to tolerance.
OSC-100
100 MHz clock oscillator (differential output) used for SERDES_PCIe_0 interface.
OSC-100
100 MHz clock oscillator (differential output) connected to RTG4 pins AB37 and AB3.
OSC-125
125 MHz clock oscillator (differential output) used for SERDES_PCIe_1 interface.
OSC-50
50 MHz single-ended clock source connected to RTG4 pin AA39
(MSIOD73PB1/GB12_23/CCC_NE0_CLKI2).
FT4232H
USB-to-quad serial ports in various configurations.
TPS3808G09DBVR
A supervisory circuit that monitors system core voltage, asserting an open-drain reset signal
when the sense voltage drops below a preset threshold or when the manual reset (MR) pin
drops to a logical low.
LM99CIMM
A remote diode temperature sensor with a two-wire System Management Bus (SMBus) serial
interface connected to pin AK31 - Temp Monitor.
HTST-110-01-L-DV
RVI header J18.
