Description
The ispLSI 2096E is a High Density Programmable Logic
Device. The device contains 96 Registers, 96 Universal
I/O pins, six Dedicated Input pins, three Dedicated Clock
Input pins, two dedicated Global OE input pins and a
Global Routing Pool (GRP). The GRP provides complete
interconnectivity between all of these elements. The
ispLSI 2096E features 5V in-system programmability
and in-system diagnostic capabilities. The ispLSI 2096E
offers non-volatile reprogrammability of all logic, as well
as the interconnect to provide truly reconfigurable sys-
tems.
The basic unit of logic on the ispLSI 2096E device is the
Generic Logic Block (GLB). The GLBs are labeled A0, A1
.. C7 (see Figure 1). There are a total of 24 GLBs in the
ispLSI 2096E 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 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, 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. By connecting
