Signal Descriptions
Signal Names
Descriptions
TMS
Input – This pin is the Test Mode Select input, which is used to control the IEEE 1149.1
state machine.
TCK
Input – This pin is the Test Clock input pin, used to clock the IEEE 1149.1 state
machine.
TDI
Input – This pin is the IEEE 1149.1 Test Data in pin, used to load data.
TDO
Output – This pin is the IEEE 1149.1 Test Data out pin used to shift data out.
TOE
Input – Test Output Enable pin. TOE tristates all I/O pins when driven low.
GOE0, GOE1
Input – Global output enable inputs.
RESET
Input – This pin resets all the registers in the device. The global polarity for this pin is
selectable on a global basis. The default is active low. An external pull-down is
required when polarity is set to active high.
yzz
Input/Output – These are the general purpose I/O used by the logic array.
y is the MFB
reference (alpha) and z is the macrocell reference (numeric)
y: A-X (768 macrocells)
y: A-P (512 macrocells)
y: A-H (256 macrocells)
z: 0-31
GND
GND – Ground
NC
No connect
VCC
VCC – The power supply pins for core logic.
VCCO0, VCCO1, VCCO2, VCCO3
VCC – The power supply pins for I/O banks 0, 1, 2, and 3.
VREF0, VREF1, VREF2, VREF3
Input – This pin defines the reference voltage for I/O banks 0, 1, 2, and 3.
GCLK0, GCLK1, GCLK2, GCLK3
Input – Global clock/clock enable inputs (see Figure 14 for differential pairing).
CLK_OUT0, CLK_OUT1
Output – Optional clock output from PLL 0 and 1.
PLL_RST0, PLL_RST1
Input – Optional input resets the M divider in PLL 0 and 1.
PLL_FBK0, PLL_FBK1
Input – Optional feedback input for PLL 0 and 1.
GNDP
GND – Ground for PLLs.
VCCP
VCC – The power supply pin for PLLs.
VCCJ
VCC – The power supply for the IEEE 1149.1 interface.
DATA
x
I/O – sysCONFIG data pins, bit
x.
CSB
Input – sysCONFIG interface chip select. Drive low to select sysCONFIG interface.
CFG0
Input – Defines SRAM configuration mode. Low: sysCONFIG port, high: E
2CMOS or
IEEE 1149.1 TAP.
PROGRAMB
Input – Controls the programming of SRAM. Hold high for normal operation. Toggle low
to reload SRAM from E
2 memory.
CCLK
1
Input – Clock for sysCONFIG interface. Reads and writes occur on the rising edge of
the clock.
READ
1
Input – Drive high to perform reads from the sysCONFIG interface.
INITB
I/O – Indicates status of configuration. Can be driven low to inhibit configuration.
DONE
Output (open drain) – Indicates status of configuration.
1. These inputs should not toggle during power up for proper power-up configuration.
