Notes:
1. Based on reliability requirements at 85°C.
2. The duration is allowed at one out of six clock cycles. If the overshoot/undershoot occurs at one out of two cycles, the
maximum overshoot/undershoot has to be reduced by 0.15 V.
I/O Power-Up and Supply Voltage Thresholds for Power-On Reset
(Commercial and Industrial)
Sophisticated power-up management circuitry is designed into every IGLOO PLUS device. These
circuits ensure easy transition from the powered-off state to the powered-up state of the device. The
many different supplies can power up in any sequence with minimized current spikes or surges. In
addition, the I/O will be in a known state through the power-up sequence. The basic principle is shown in
Figure 2-1 on page
There are five regions to consider during power-up.
IGLOO PLUS I/Os are activated only if ALL of the following three conditions are met:
VCCI Trip Point:
Ramping up (V5 devices): 0.6 V < trip_point_up < 1.2 V
Ramping down (V5 devices): 0.5 V < trip_point_down < 1.1 V
Ramping up (V2 devices): 0.75 V < trip_point_up < 1.05 V
Ramping down (V2 devices): 0.65 V < trip_point_down < 0.95 V
VCC Trip Point:
Ramping up (V5 devices): 0.6 V < trip_point_up < 1.1 V
Ramping down (V5 devices): 0.5 V < trip_point_down < 1.0 V
Ramping up (V2 devices): 0.65 V < trip_point_up < 1.05 V
Ramping down (V2 devices): 0.55 V < trip_point_down < 0.95 V
VCC and VCCI ramp-up trip points are about 100 mV higher than ramp-down trip points. This specifically
built-in hysteresis prevents undesirable power-up oscillations and current surges. Note the following:
1. VCC and VCCI are above the minimum specified trip points
2. VCCI > VCC – 0.75 V (typical)
3. Chip is in the operating mode.

During programming, I/Os become tristated and weakly pulled up to VCCI.
JTAG supply, PLL power supplies, and charge pump VPUMP supply have no influence on I/O
behavior.
