3.3-V I/O Power Static Current Issue
Cyclone III Device Family Errata Sheet
Note to
(1) Impedances as listed result in a V
(2) Impedance is over the range of DC to 2.4 MHz.
(3) Minimum capacitors at one each per Cyclone III device to meet the transition current surge. Normal user mode operation likely requires
additional bulk and decoupling capacitors.

Supply Impedance and Typical Capacitors
If you use JTAG for initialization, the duration of the current surge is a maximum of
74 TCK clock periods. If you use the CLKUSR pin for initialization, the duration of the
current surge is a maximum of 74 CLKUSR clock periods. Otherwise, the duration of
the current surge is a maximum of 15 s. The fastest rise time within the surge is
150 ns.
To ensure V

Cyclone III FPGA Starter Kit board (3C25) and the Cyclone III FPGA Development Kit
board (3C120) are below the maximum impedances.
Altera has identified an issue with static current in I/O banks powered at 3.3-V V
on Cyclone III EP3C25 Revision B and C and EP3C120 Revision A and B engineering
sample devices. The affected devices might draw more current than expected as
stated in
designing the V
powered at 3.15 V V
Table 6. Additional I/O Current
This issue will be fixed in production silicon for the EP3C25 Revision D and EP3C120
Revision C and their later revisions.
Note to
(1) This current increase per 3.3-V I/O bank is in addition to the existing power estimations shown in the PowerPlay
Early Power Estimator or Quartus II PowerPlay Power Analyzer tools.
