Description
The ispLSI 2128VE is a High Density Programmable
Logic Device available in 128 and 64 I/O-pin versions.
The device contains 128 Registers, eight Dedicated
Input pins, three Dedicated Clock Input pins, two dedi-
cated Global OE input pins and a Global Routing Pool
(GRP). The GRP provides complete interconnectivity
between all of these elements. The ispLSI 2128VE
features in-system programmability through the Bound-
ary Scan Test Access Port (TAP) and is 100% IEEE
1149.1 Boundary Scan Testable. The ispLSI 2128VE
offers non-volatile reprogrammability of the logic, as well
as the interconnect to provide truly reconfigurable sys-
tems.
The basic unit of logic on the ispLSI 2128VE 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 2128VE 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.

*Not available on 84-PLCC Device
The 128-I/O 2128VE contains 128 I/O cells, while the 64-
I/O version contains 64 I/O cells. Each I/O cell is directly
connected to an I/O pin and can be individually pro-
grammed 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 4mA or sink 8mA. Each output can be
programmed independently for fast or slow output slew
rate to minimize overall output switching noise. Device
pins can be safely driven to 5V signal levels to support
mixed-voltage systems.
Eight GLBs, 32 or 16 I/O cells, two dedicated inputs and
two or one ORPs are connected together to make a
Megablock (see Figure 1). The outputs of the eight GLBs
are connected to a set of 32 or 16 universal I/O cells by
the two or one ORPs. Each ispLSI 2128VE 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 2128VE 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 2128VE 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 totem-pole configuration.
The open-drain/totem-pole option is selectable through
the Lattice software tools.
