Hot Socketing
The LatticeXP devices have been carefully designed to ensure predictable behavior during power-up and power-
down. Power supplies can be sequenced in any order. During power up and power-down sequences, the I/Os
remain in tristate until the power supply voltage is high enough to ensure reliable operation. In addition, leakage
into I/O pins is controlled to within specified limits, which allows easy integration with the rest of the system.
These capabilities make the LatticeXP ideal for many multiple power supply and hot-swap applications.
Sleep Mode
The LatticeXP “C” devices (V
to three orders of magnitude during periods of system inactivity. Entry and exit to Sleep Mode is controlled by the
SLEEPN pin.
During Sleep Mode, the FPGA logic is non-operational, registers and EBR contents are not maintained and I/Os
are tri-stated. Do not enter Sleep Mode during device programming or configuration operation. In Sleep Mode,
power supplies can be maintained in their normal operating range, eliminating the need for external switching of
power supplies. Table 2-9 compares the characteristics of Normal, Off and Sleep Modes.
