Embedded Trace Macro (ETM) cell
header
ETM header for debugging.
PCI Express (PCIe) edge connector PCIe edge connector with four lanes.
Light-emitting diodes (LEDs)
Eight active-high LEDs connected to some of the user I/Os for debugging.
Push-button reset
Push-button system reset for the SmartFusion2 device.
Push-button switches
Four push-button switches for testing and navigation.
FMC HPC connector (J30)
High pin count FMC header to connect the external daughter boards.
Connector array socket 400 pins (40 × 10), 1.27 mm pitch. Unused MSIO pins
routed from the SmartFusion2 device to the J30 connector.
FMC LPC connector (J60)
Low pin count FMC header to connect the external daughter boards.
Connector array socket 160 pins (40 × 4), 1.27 mm. Unused MSIOD pins
routed from the SmartFusion2 device to the J60 connector.
USB interface
USB Micro-AB connector, interfacing with the high speed USB2.0 ULPI
transceiver chip USB3320, which, in turn, interfaces with USB-D port of the
SmartFusion2 MSS.
DS1818 3.3V EconoReset
A simple three-pin voltage monitor and power-on reset that holds reset for 150
ms for stabilization after power returns to tolerance.
OSC-100
100 MHz clock oscillator with differential output.
OSC-125
125 MHz clock oscillator with differential output.
OSC-50
50 MHz clock oscillator.
OSC-32
32.768 KHz low-power oscillator.
FT4232H
USB-to-quad serial ports in various configurations.
TPS3808G09DBVR
Supervisory circuit that monitors system voltage of 0.9 V, 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.
I2C port header
16-pin header available for I2C0 and I2C1 interfaces of the SmartFusion2
device.
