Generic Logic
Blocks (GLBs)
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 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.
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 two ORPs. Each
ispLSI 2128E 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 2128E 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 2128E 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 ispDesignEXPERT software tools.
