Functional Block Diagram

Figure 1. ispLSI 1048E Functional Block Diagram

The device also has 96 I/O cells, each of which is directly

connected to an I/O pin. Each I/O cell can be individually

programmed to be a combinatorial input, registered in-

put,

latched

input,

output

or

bi-directional

I/O pin with 3-state control. The signal levels are TTL

compatible voltages and the output drivers can source 4

mA or sink 8 mA. Each output can be programmed

independently for fast or slow output slew rate to mini-

mize overall output switching noise.

Eight GLBs, 16 I/O cells, two dedicated inputs and one

ORP are connected together to make a Megablock (see

figure 1). The outputs of the eight GLBs are connected to

a set of 16 universal I/O cells by the ORP. Each ispLSI

1048E device contains six Megablocks.

The GRP has, as its inputs, the outputs from all of the

GLBs and all of the inputs from the bi-directional I/O cells.

All of these signals are made available to the inputs of the

GLBs. Delays through the GRP have been equalized to

minimize timing skew.

Clocks in the ispLSI 1048E device are selected using the

Clock Distribution Network. Four dedicated clock pins

(Y0, Y1, Y2 and Y3) are brought into the distribution

network, and five clock outputs (CLK 0, CLK 1, CLK 2,

IOCLK 0 and IOCLK 1) are provided to route clocks to the

GLBs and I/O cells. The Clock Distribution Network can

also be driven from a special clock GLB (D0). The logic

of this GLB allows the user to create an internal clock

from a combination of internal signals within the device.
