Description
The ispLSI and pLSI 1032E are High Density Programmable Logic Devices 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 features 5-Volt
in-system programmability and in-system diagnostic capabilities. The ispLSI 1032E device offers non-volatile
reprogrammability of the logic, as well as the interconnects to provide truly reconfigurable systems. It is
architecturally and parametrically compatible to the pLSI
1032E device, but multiplexes four input pins to control
in-system programming. A functional superset of the
ispLSI and pLSI 1032 architecture, the ispLSI and pLSI
1032E devices add two new global output enable pins.
The basic unit of logic on the ispLSI and pLSI 1032E
devices 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 and pLSI 1032E devices. Each GLB
has 18 inputs, a programmable 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.

The devices also have 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 input, 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 minimize 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
and pLSI 1032E device contains four 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 and pLSI 1032E devices 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 and pLSI 1032E devices). The
logic of this GLB allows the user to create an internal
clock from a combination of internal signals within the
device.
