Revision 10 5-1
5 – Pin Descriptions
Supply Pins
Name Type Description
GND Ground Digital ground to the FPGA fabric, microcontroller subsystem and GPIOs
GND15ADC0 Ground Quiet analog ground to the 1.5 V circuitry of the first analog-to-digital converter (ADC)
GND15ADC1 Ground Quiet analog ground to the 1.5 V circuitry of the second ADC
GND15ADC2 Ground Quite analog ground to the 1.5 V circuitry of the third ADC
GND33ADC0 Ground Quiet analog ground to the 3.3 V circuitry of the first ADC
GND33ADC1 Ground Quiet analog ground to the 3.3 V circuitry of the second ADC
GND33ADC2 Ground Quiet analog ground to the 3.3 V circuitry of the third ADC
GNDA Ground Quiet analog ground to the analog front-end
GNDAQ Ground Quiet analog ground to the analog I/O of SmartFusion
cSoCs
GNDENVM Ground Digital ground to the embedded nonvolatile memory (eNVM)
GNDLPXTAL Ground Analog ground to the low power 32 KHz crystal oscillator circuitry
GNDMAINXTAL Ground Analog ground to the main crystal oscillator circuitry
GNDQ Ground Quiet digital ground supply voltage to input buffers of I/O banks. Within the package, the
GNDQ plane is decoupled from the simultaneous switching noise originated from the
output buffer ground domain. This minimizes the noise transfer within the package and
improves input signal integrity. GNDQ needs to always be connected on the board to
GND.
GNDRCOSC Ground Analog ground to the integrated RC oscillator circuit
GNDSDD0 Ground Analog ground to the first sigma-delta DAC
GNDSDD1 Ground Common analog ground to the second and third sigma-delta DACs
GNDTM0 Ground Analog temperature monitor common ground for signal conditioning blocks SCB 0 and
SCB 1 (see information for pins "TM0" and "TM1" in the "Analog Front-End (AFE)"
section on page 5-14).
GNDTM1 Ground Analog temperature monitor common ground for signal conditioning block SCB 2 and
SBCB 3 (see information for pins "TM2" and "TM3" in the "Analog Front-End (AFE)"
section on page 5-14).
GNDTM2 Ground Analog temperature monitor common ground for signal conditioning block SCB4
GNDVAREF Ground Analog ground reference used by the ADC. This pad should be connected to a quiet
analog ground.
VCC Supply Digital supply to the FPGA fabric and MSS, nominally 1.5 V. VCC is also required for
powering the JTAG state machine, in addition to VJTAG. Even when a SmartFusion
cSoC is in bypass mode in a JTAG chain of interconnected devices, both VCC and
VJTAG must remain powered to allow JTAG signals to pass through the SmartFusion
cSoC.
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.
