Description
The ispLSI 2032VE is a High Density Programmable
Logic Device that can be used in both 3.3V and 5V
systems. 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 2032VE features in-system programmability
through the Boundary Scan Test Access Port (TAP) and
is 100% IEEE 1149.1 Boundary Scan Testable. The
ispLSI 2032VE 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 2032VE 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 2032VE 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 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 pro-
grammed independently for fast or slow output slew rate
to minimize overall output switching noise. Device pins
can be safely driven to 5 Volt signal levels to support
mixed-voltage systems.
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 ORPs. Each
ispLSI 2032VE 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 2032VE 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 2032VE are individually program-
mable, 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 pro-
grammable fuse. The default configuration when the
device is in bulk erased state is the totem-pole configu-
ration. The open-drain/totem-pole option is selectable
through the Lattice design tools.
