7 Hardware Overview

Here is an overview of FC6100 ASPEN Hardware design.
For more details, the FC6100 ASPEN Hardware Integration Guide can be sent upon request.

7.1 Memory

FC6100 ASPEN Memory configuration:
Up to 8Gbits NAND Flash and 4 Gbits mDDR RAM.

7.2 Power domains

FC6100 ASPEN's processor's digital I/O are mainly referenced to a 1.8V voltage.
Historically, Parrot interface uses 3.3V interface.
However, some customers might already use 1.8V signaling on their motherboard and level-shifting
would then become redundant.
The decision was then made to move level-shifting function on the motherboard to improve the
flexibility of the design and the module size.
Consequently, FC6100 ASPEN digital I/Os belong to 2 different power domains:
•
3.3V signaling
•
1.8V signaling

7.3 Power supplies

•
3V3_MAIN
To operate, the module requires a unique 3.3V voltage power supply called 3V3_MAIN with a 10%
precision and capable to deliver up to 1A.
3V3_MAIN is internally monitored and triggers power on and power down sequence of the module.
•
VDD_PERM
In cases where RTC option is needed, for time-keeping, the motherboard must also supply the board
permanently with another 3.3V voltage called VDD_PERM.
•
1V8_IO
For customers that do not have any 1.8V voltage level power supply, the module outputs a 1V8_IO
power supply that can be used to power level-shifter and 1.8V external devices I/O pads.

7.4 Digital communication links

FC6100 ASPEN module uses several means to interface with the system it is integrated in.

7.4.1 Control signals

Some discrete signals are used by the module to interact with the rest of the system:
•
RESET_HOSTn is the module's reset input
•
S_RESETOUTn & H_RESETOUTn inform the motherboard of the reset state of the
module
•
BOOTS is an input which activates firmware update
