Fusion Family of Mixed Signal FPGAs
Revision 4
2-33
Real-Time Counter System
The RTC system enables Fusion devices to support standby and sleep modes of operation to reduce
power consumption in many applications.
Sleep mode, typical 10 µA
Standby mode (RTC running), typical 3 mA with 20 MHz
The RTC system is composed of five cores:
RTC sub-block inside Analog Block (AB)
Voltage Regulator and Power System Monitor (VRPSM)
Crystal oscillator (XTLOSC); refer to the "Crystal Oscillator" section in the Fusion Clock
Resources chapter of the Fusion FPGA Fabric User’s Guide for more detail.
Crystal clock; does not require instantiation in RTL
1.5 V voltage regulator; does not require instantiation in RTL
All cores are powered by 3.3 V supplies, so the RTC system is operational without a 1.5 V supply during
standby mode. Figure 2-27 shows their connection.
Notes:
1. Signals are hardwired internally and do not exist in the macro core.
2. User is only required to instantiate the VRPSM macro if the user wishes to specify PUPO behavior of the voltage regulator
to be different from the default, or employ user logic to shut the voltage regulator off.
