sysIO Banks
The inputs and outputs of ispGDX2 devices are divided into eight sysIO banks, where each bank is capable of sup-
porting different I/O standards. The number of I/Os per bank is 32, 16 and 8 for the 256-, 128- and 64-I/O devices
respectively. Each sysIO bank has its own I/O supply voltage (V
bank complete independence from the other banks. Each I/O within a bank can be individually configured to any
standard consistent with the V
The I/O of the ispGDX2 devices contain a programmable strength and slew rate tri-state output buffer, a program-
mable input buffer, a programmable pull-up resistor, a programmable pull-down resistor and a programmable bus-
keeper latch. These programmable capabilities allow the support of a wide range of I/O standards.
