MODE
Input Static Selects burst order. When tied to GND selects linear burst sequence. When tied to VDD or left floating
selects interleaved burst sequence. This is a strap pin and must remain static during device operation.
Mode pin has an internal pull-up.
VDD
Power Supply Power supply inputs to the core of the device.
VDDQ
I/O Power
Supply
Power supply for the I/O circuitry.
VSS
Ground
Ground for the core of the device.
VSSQ
I/O Ground Ground for the I/O circuitry.
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 being used, this pin can 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 being
used, this pin can be left floating or connected to VDD 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 being
used, this pin can be disconnected or connected to VDD. This pin is not available on TQFP packages.
TCK
JTAG
Clock
Clock input to the JTAG circuitry. If the JTAG feature is not being used, this pin must be connected
to VSS. This pin is not available on TQFP packages.
NC
No connects. Not internally connected to the die. 36M, 72M, 144M, 288M, 576M, and 1G are address
expansion pins and are not internally connected to the die.
VSS/DNU
Ground/DNU This pin can be connected to ground or can be left floating.
