Input-Static
Selects Burst Order
. When tied to GND selects linear burst sequence. When tied to
V
DD
or left floating selects interleaved burst sequence. This is a strap pin and should
remain static during device operation. Mode Pin has an internal pull up.
TDO
JTAG Serial
Output
Synchronous
Serial data-out to the JTAG circuit
. Delivers data on the negative edge of TCK. If
the JTAG feature is not used, this pin should be left unconnected. This pin is not
available on TQFP packages.
TDI
JTAG Serial
Input
Synchronous
Serial data-in to the JTAG circuit
. Sampled on the rising edge of TCK. If the JTAG
feature is not used, this pin can be left floating or connected to V
DD
through a pull up
resistor. This pin is not available on TQFP packages.
TMS
JTAG Serial
Input
Synchronous
Serial data-in to the JTAG circuit
. Sampled on the rising edge of TCK. If the JTAG
feature is not used, this pin can be disconnected or connected to V
DD
. This pin is not
available on TQFP packages.
TCK
JTAG Clock
Clock input to the JTAG circuitry
. If the JTAG feature is not used, this pin must be
connected to V
SS
. This pin is not available on TQFP packages.
No Connects
. Not internally connected to the die. 144M, 288M, 576M, and 1G are
address expansion pins are not internally connected to the die.
