The ispLSI 1032E is a High Density Programmable Logic
Device containing 192 Registers, 64 Universal I/O pins,
eight Dedicated Input pins, four Dedicated Clock Input
pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The ispLSI 1032E device offers 5V non-vola-
tile in-system programmability of the logic, as well as the
interconnects to provide truly reconfigurable systems. A
functional superset of the ispLSI 1032 architecture, the
ispLSI 1032E device adds two new global output enable
pins.
The basic unit of logic on the ispLSI 1032E device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1…D7 (see Figure 1). There are a total of 32 GLBs in the
ispLSI 1032E device. Each GLB has 18 inputs, a pro-
grammable AND/OR/Exclusive OR array, and four outputs
which can be configured to be either combinatorial or
registered. Inputs to the GLB come from the GRP and
dedicated inputs. All of the GLB outputs are brought back
into the GRP so that they can be connected to the inputs
of any GLB on the device.

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
1032E device contains four Megablocks.

p
The device also has 64 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.

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 1032E 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 (C0 on the ispLSI
1032E device). The logic of this GLB allows the user to
create an internal clock from a combination of internal
signals within the device.
