A JTAG chain can contain several different devices. However, you must be cautious if
the chain contains devices that have different V
the TDO pin must meet the specifications of the TDI pin it drives. For Cyclone III
device family, the TDO pin is powered by the V
supply is 3.3 V, the TDO pin drives out 3.3 V.
Devices can interface with each other although they might have different V
For example, a device with a 3.3-V TDO pin can drive to a device with a 5.0-V TDI pin
because 3.3 V meets the minimum TTL-level V
Cyclone III device family can support 2.5-V or 3.3-V input levels.
For multiple devices in a JTAG chain with 3.0-V or 3.3-V I/O standard, you must
connect a 25-Ω series resistor on a TDO pin driving a TDI pin.
You can also interface the TDI and TDO lines of the devices that have different V
levels by inserting a level shifter between the devices. If possible, the JTAG chain must
be built in such a way that a device with a higher V
equal or lower V
TDO level to a level acceptable to the JTAG tester.

Timing requirements for IEEE Std. 1149.1 signals
Instruction mode
Mandatory JTAG instructions (SAMPLE/PRELOAD, EXTEST and BYPASS)
Optional JTAG instructions (IDCODE, USERCODE, CLAMP and HIGHZ)
Only the three mandatory JTAG 1149.1 JTAG instructions (BYPASS,
SAMPLE/PRELOAD, EXTEST) and the FACTORY private instruction are supported
from the JTAG pins upon power up. The FACTORY instruction (instruction code:
10 1000 0001) must be issued before the device starts loading the core
configuration data to enable access to all other JTAG instructions. This instruction
also clears the device configuration data and AES volatile key.
IDCODE instruction is not supported upon power-up, prior to issuing the
FACTORY instruction. However, it is the default instruction when the TAP
controller is in the reset state. Without loading any instructions, you can go to the
Shift_DR state and shift out the JTAG Device ID.
IDCODE, CONFIG_IO, ACTIVE_DISENGAGE, HIGHZ, CLAMP, USERCODE and
PULSE_NCONFIG instructions are supported, provided that the FACTORY
instruction is executed.
