Specifications ispLSI 1016E

Input - This pin performs two functions. When

ispEN is logic low, it functions

as an input pin to load programming data into the device. It is a dedicated

input pin when

ispEN is logic high.SDI/IN0 also is used as one of the two

control pins for the isp state machine.

Dedicated Clock input. This clock input is connected to one of the clock

inputs of all the GLBs on the device.

This pin performs two functions:

Input - Dedicated in-system programming enable input pin. This pin is

brought low to enable the programming mode. The MODE, SDI, SDO and

SCLK controls become active.

This is a dual function pin. It can be used either as Global Output Enable for

all I/O cells or it can be used as a dedicated input pin.

Input/Output Pins - These are the general purpose I/O pins used by the logic

array.

Input - This pin performs two functions. When

ispEN is logic low, it functions

as a pin to control the operation of the isp state machine. It is a dedicated

input pin when

ispEN is logic high.

- Dedicated clock input. This clock input is brought into the Clock

Distribution Network, and can optionally be routed to any GLB and/or

I/O cell on the device.

Output/Input - This pin performs two functions. When

ispEN is logic low, it

functions as an output pin to read serial shift register data. It is a dedicated

input pin when

ispEN is logic high.

Input - This pin performs two functions. When

ispEN is logic low, it

functions as a clock pin for the Serial Shift Register. It is a dedicated clock

input when

ispEN is logic high. This clock input is brought into the Clock

Distribution Network, and can optionally be routed to any GLB and/or I/O

cell on the device.

Ground (GND)

- Active Low (0) Reset pin which resets all of the GLB and I/O registers

in the device.
