Instant-On Support
In some applications, it is necessary for a device to wake up very quickly to begin operation. The MAX 10
device offers the instant-on feature to support fast wake-up time applications. With the instant-on feature,
MAX 10 devices can directly enter configuration mode without any POR delay after the POR trips for the
monitored power supplies. Then your design can be configured from internal configuration flash memory
(CFM). This feature provides the shortest time to enter user mode as a whole.
To benefit from the instant-on feature of the MAX 10 device, there is a power-up sequence and ramp time
requirement to follow. The following table shows the power-up sequence requirement for different power
supply device options. For the minimum and maximum ramp time, refer to the recommended operating
conditions in the
MAX 10 FPGA Device Datasheet
.

Power Management Controller Scheme
The power management controller scheme allows you to allocate some applications in sleep mode during
runtime. This enables you to to turn off portions of the design, thus reducing dynamic power consump‐
tion. You can re-enable your application with a fast wake-up time of less than 1 ms.

Global Clock Network
The MAX 10 device contains hardware features that enable I/O power down and global clock (GCLK)
gating to manage low-power state during sleep mode. You can power down the I/O buffer dynamically
when your application is in idle or sleep mode. One example is the digital single lens reflex DSLR camera
