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.
