Description

Power Supply Power Supply Inputs to the Core of the Device.

IO Power Supply Power Supply for the IO Circuitry.

Ground

Ground for the Core of the Device.

IO Ground Ground for the IO Circuitry.

JTAG serial output Serial Data-Out to the JTAG Circuit. Delivers data on the negative edge of TCK. If the JTAG

Synchronous feature is not being utilized, this pin should be left unconnected. This pin is not available on TQFP

packages.

JTAG serial input Serial Data-In to the JTAG Circuit. Sampled on the rising edge of TCK. If the JTAG feature is

Synchronous not being utilized, this pin can be left floating or connected to VDD through a pull up resistor. This

pin is not available on TQFP packages.

JTAG serial input Serial Data-In to the JTAG Circuit. Sampled on the rising edge of TCK. If the JTAG feature is

Synchronous not being utilized, this pin can be disconnected or connected to VDD. This pin is not available on

TQFP packages.

JTAG-Clock

-

Clock Input to the JTAG Circuitry. If the JTAG feature is not being utilized, this pin must be

connected to VSS. This pin is not available on TQFP packages.

No Connects. Not internally connected to the die. 72M, 144M and 288M are address expansion

pins are not internally connected to the die.
