Description
The ispLSI 2032E is a High Density Programmable Logic
Device. The device contains 32 Registers, 32 Universal
I/O pins, two Dedicated Input Pins, three Dedicated
Clock Input Pins, one dedicated Global OE input pin and
a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements.
The ispLSI 2032E features 5V in-system programmability and in-system diagnostic capabilities. The ispLSI
2032E offers non-volatile reprogrammability of the logic,
as well as the interconnect to provide truly reconfigurable
systems.
The basic unit of logic on the ispLSI 2032E device is the
Generic Logic Block (GLB). The GLBs are labeled A0, A1
.. A7 (see Figure 1). There are a total of eight GLBs in the
ispLSI 2032E device. Each GLB is made up of four
macrocells. 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 device also has 32 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, output or bidirectional 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. By connecting
the VCCIO pins to a common 5V or 3.3V power supply,
I/O output levels can be matched to 5V or 3.3V compatible voltages. When connected to a 5V supply, the I/O
pins provide PCI-compatible output drive (48-pin device
only).
Eight GLBs, 32 I/O cells, two dedicated inputs and two
ORPs are connected together to make a Megablock (see
Figure 1). The outputs of the eight GLBs are connected
to a set of 32 universal I/O cells by the ORP. Each ispLSI
2032E device contains one Megablock.
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 2032E device are selected using the
dedicated clock pins. Three dedicated clock pins (Y0, Y1,
Y2) or an asynchronous clock can be selected on a GLB
basis. The asynchronous or Product Term clock can be
generated in any GLB for its own clock.
Programmable Open-Drain Outputs
In addition to the standard output configuration, the
outputs of the ispLSI 2032E are individually programmable, either as a standard totem-pole output or an
open-drain output. The totem-pole output drives the
specified Voh and Vol levels, whereas the open-drain
output drives only the specified Vol. The Voh level on the
open-drain output depends on the external loading and
pull-up. This output configuration is controlled by a programmable fuse. The default configuration when the
device is in bulk erased state is totem-pole configuration.
The open-drain/totem-pole option is selectable through
the Lattice software tools.
