Pin Descriptions
5-2 Revision 10
VCC15A Supply Clean analog 1.5 V supply to the analog circuitry. Always power this pin.
VCC15ADC0 Supply Analog 1.5 V supply to the first ADC. Always power this pin.
VCC15ADC1 Supply Analog 1.5 V supply to the second ADC. Always power this pin.
VCC15ADC2 Supply Analog 1.5 V supply to the third ADC. Always power this pin.
VCC33A Supply Clean 3.3 V analog supply to the analog circuitry. VCC33A is also used to feed the
1.5 V voltage regulator for designs that do not provide an external supply to VCC. Refer
to the Voltage Regulator (VR), Power Supply Monitor (PSM), and Power Modes section
in the SmartFusion Microcontroller Subsystem User’s Guide for more information.
VCC33ADC0 Supply Analog 3.3 V supply to the first ADC. If unused, Microsemi recommends connecting this
pin to a 3.3 V supply
.
1
VCC33ADC1 Supply Analog 3.3 V supply to the second ADC. If unused, Microsemi recommends connecting
this pin to a 3.3 V supply.
1
VCC33ADC2 Supply Analog 3.3 V supply to the third ADC. If unused, Microsemi recommends connecting
this pin to a 3.3 V supply.
1
VCC33AP Supply Analog clean 3.3 V supply to the charge pump. To avoid high current draw, VCC33AP
should be powered up simultaneously with or after VCC33A. Can be pulled down if
unused.
1
VCC33N Supply –3.3 V output from the voltage converter. A 2.2 µF capacitor must be connected from
this pin to GND. Analog charge pump capacitors are not needed if none of the analog
SCB features are used and none of the SDDs are used. In that case it should be left
unconnected.
VCC33SDD0 Supply Analog 3.3 V supply to the first sigma-delta DAC
VCC33SDD1 Supply Common analog 3.3 V supply to the second and third sigma-delta DACs
VCCENVM Supply Digital 1.5 V power supply to the embedded nonvolatile memory blocks. To avoid high
current draw, VCC should be powered up before or simultaneously with VCCENVM.
VCCESRAM Supply Digital 1.5 V power supply to the embedded SRAM blocks. Available only on the
208PQFP package. It should be connected to VCC (in other packages, it is internally
connected to VCC).
VCCFPGAIOB0 Supply Digital supply to the FPGA fabric I/O bank 0 (north FPGA I/O bank) for the output
buffers and I/O logic.
Each bank can have a separate VCCFPGAIO connection. All I/Os in a bank will run off
the same VCCFPGAIO supply. VCCFPGAIO can be 1.5 V, 1.8 V, 2.5 V, or 3.3 V,
nominal voltage. Unused I/O banks should have their corresponding VCCFPGAIO pins
tied to GND.
VCCFPGAIOB1 Supply Digital supply to the FPGA fabric I/O bank 1 (east FPGA I/O bank) for the output buffers
and I/O logic.
Each bank can have a separate VCCFPGAIO connection. All I/Os in a bank will run off
the same VCCFPGAIO supply. VCCFPGAIO can be 1.5 V, 1.8 V, 2.5 V, or 3.3 V,
nominal voltage. Unused I/O banks should have their corresponding VCCFPGAIO pins
tied to GND.
Name Type Description
Notes:
1. The following 3.3 V supplies should be connected together while following proper noise filtering practices: VCC33A,
VCC33ADCx, VCC33AP, VCC33SDDx, VCCMAINXTAL, and VCCLPXTAL.
2. The following 1.5 V supplies should be connected together while following proper noise filtering practices: VCC,
VCC15A, and VCC15ADCx.
3. For more details on VCCPLLx capacitor recommendations, refer to the application note AC359, SmartFusion cSoC
Board Design Guidelines, the "PLL Power Supply Decoupling Scheme" section.
