–
D0 is the DATA output pin to provide data for configuring an
FPGA in serial mode. The D0 output is set to a
high-impedance state during ISPEN (when not clamped).
Configuration Clock Input. Each rising edge on the CLK input
increments the internal address counter if the CLK input is
selected, CE is Low, and OE/RESET is High.
Output Enable/Reset (Open-Drain I/O). When Low, this input
holds the address counter reset and the DATA output is in a
high-impedance state. This is a bidirectional open-drain pin
that is held Low while the PROM completes the internal
power-on reset sequence. Polarity is not programmable.
Chip Enable Input. When CE is High, the device is put into
low-power standby mode, the address counter is reset, and
the DATA pins are put in a high-impedance state.
Configuration Pulse (Open-Drain Output). Allows JTAG
CONFIG instruction to initiate FPGA configuration without
powering down FPGA. This is an open-drain output that is
pulsed Low by the JTAG CONFIG command.
Chip Enable Output. Chip Enable Output (CEO) is connected
to the CE input of the next PROM in the chain. This output is
Low when CE is Low and OE/RESET input is High, AND the
internal address counter has been incremented beyond its
Terminal Count (TC) value. CEO returns to High when
OE/RESET goes Low or CE goes High.
JTAG Mode Select Input. The state of TMS on the rising edge
of TCK determines the state transitions at the Test Access
Port (TAP) controller. TMS has an internal 50 KΩ resistive
pull-up to V
not driven.
JTAG Clock Input. This pin is the JTAG test clock. It
sequences the TAP controller and all the JTAG test and
programming electronics.
JTAG Serial Data Input. This pin is the serial input to all JTAG
instruction and data registers. TDI has an internal 50 KΩ
resistive pull-up to V
pin is not driven.
JTAG Serial Data Output. This pin is the serial output for all
JTAG instruction and data registers. TDO has an internal
50 KΩ resistive pull-up to V
system if the pin is not driven.
+3.3V Supply. Positive 3.3V supply voltage for internal logic.
