IGLOO DC and Switching Characteristics

PLL Behavior at Brownout Condition
Actel recommends using monotonic power supplies or voltage regulators to ensure proper power-
up behavior. Power ramp-up should be monotonic at least until VCC and VCCPLX exceed brownout
activation levels (see Figure 2-1 and Figure 2-2 on page 2-5 for more details).
When PLL power supply voltage and/or VCC levels drop below the VCC brownout levels (0.75 V ±
0.25 V for V5 devices, and 0.75 V ± 0.2 V for V2 devices), the PLL output lock signal goes low and/or
the output clock is lost. Refer to the Brownout Voltage section in the Power-Up/-Down Behavior of
Low-Power Flash Devices chapter of the ProASIC®3 and ProASIC3E handbooks for information on
clock and lock recovery.
Internal Power-Up Activation Sequence
1. Core
2. Input buffers
3. Output buffers, after 200 ns delay from input buffer activation
To make sure the transition from input buffers to output buffers is clean, ensure that there is no
path longer than 100 ns from input buffer to output buffer in your design.
Figure 2-1 • V5 Devices – I/O State as a Function of VCCI and VCC Voltage Levels
Region 1: I/O buffers are OFF
Region 2: I/O buffers are ON.
I/Os are functional (except differential inputs)
but slower because V
CCI
/V
CC
are below
specification. For the same reason, input
buffers do not meet V
IH
/V
IL
levels, and
output buffers do not meet V
OH
/V
OL
levels.

Region 4: I/O

I/Os are functional

Region 4: I/O
buffers are ON.
I/Os are functional
(except differential inputs)
where VT can be from 0.58 V to 0.9 V (typically 0.75 V)
VCCI
Region 3: I/O buffers are ON.
I/Os are functional; I/O DC
specifications are met,
but I/Os are slower because
the V
CC
is below specification.
