(1) This information is preliminary.
(2) This value is applicable if users do not delay configuration by extending the nCONFIG or nSTATUS low pulse width.
(3) The minimum and maximum numbers apply only if the internal oscillator is chosen as the clock source for starting up the device.
(4) Cyclone III EP3C5, EP3C10, EP3C16, EP3C25, and EP3C40 devices support a DCLK f

JTAG has developed a specification for boundary-scan testing. This boundary-scan
test (BST) architecture offers the capability to efficiently test components on PCBs
with tight lead spacing. The BST architecture can test pin connections without using
physical test probes and capture functional data while a device is operating normally.
You can also use the JTAG circuitry to shift configuration data into the device. The
Quartus II software automatically generates .sofs that are used for JTAG
configuration with a download cable in the Quartus II software programmer.
For more information about JTAG boundary-scan testing, refer to the
(JTAG) Boundary-Scan Testing for Cyclone III Devices
JTAG instructions have precedence over any other device configuration modes.
Therefore, JTAG configuration can take place without waiting for other configuration
modes to complete. For example, if you attempt JTAG configuration of Cyclone III
device family during PS configuration, PS configuration terminates and JTAG
configuration begins. If the Cyclone III device family MSEL pins are set to AS mode,
the Cyclone III device family does not output a DCLK signal when JTAG configuration
takes place.
The four required pins for a device operating in JTAG mode are TDI, TDO, TMS, and
TCK. The TCK pin has an internal weak pull-down resistor while the TDI and TMS pins
have weak internal pull-up resistors (typically 25 kΩ). The TDO output pin is powered
by V
JTAG pins support only LVTTL I/O standard. All user I/O pins are tri-stated during
JTAG configuration.
The TDO output is powered by the V
