Description
The ispLSI 3192 is a High Density Programmable Logic
Device containing 384 Registers, 192 Universal I/O pins,
five Dedicated Clock Input Pins, twelve Output Routing
Pools (ORP), and a Global Routing Pool (GRP) which
allows complete inter-connectivity between all of these
elements. The ispLSI 3192 features 5-Volt in-system
programmability and in-system diagnostic capabilities.
The ispLSI 3192 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 3192 device is the
Twin Generic Logic Block (Twin GLB) labelled A0, A1...F3.
There are a total of 24 of these Twin GLBs in the ispLSI
3192 device. Each Twin GLB has 24 inputs, a program-
mable AND array and two OR/Exclusive-OR Arrays, and
eight outputs which can be configured to be either com-
binatorial or registered. All Twin GLB inputs come from
the GRP.

Description (Continued)
All local logic block outputs are brought back into the
GRP so they can be connected to the inputs of any other
logic block on the device. The device also has 192 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, a registered input, a latched input, an
output or a 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.
The 192 I/O Cells are grouped into six sets of 32 bits.
Each of these I/O groups is associated with a logic
Megablock through the use of the ORP. Each Megablock
is able to provide one Product Term Output Enable
(PTOE) signal which is globally distributed to all I/O cells.
That PTOE signal can be generated within any GLB in the
Megablock. Each I/O cell can select either a Global OE
or a PTOE.
Four Twin GLBs, 32 I/O Cells and two ORPs are con-
nected together to make a logic Megablock. The
Megablock is defined by the resources that it shares. The
outputs of the four Twin GLBs are connected to a set of
32 I/O cells by the two ORPs. The ispLSI 3192 device
contains six of these Megablocks.
The GRP has as its inputs the outputs from all of the Twin
GLBs and all of the inputs from the bidirectional I/O cells.
All of these signals are made available to the inputs of the
Twin GLBs. Delays through the GRP have been equal-
ized to minimize timing skew and logic glitching.
Clocks in the ispLSI 3192 device are provided through
five dedicated clock pins. The five pins provide three
clocks to the Twin GLBs and two clocks to the I/O cells.
The table below lists key attributes of the device along
with the number of resources available.
An additional feature of the ispLSI 3192 is the Boundary
Scan capability, which is composed of cells connected
between the on-chip system logic and the device's input
and output pins. All I/O pins have associated boundary
scan registers, with 3-state I/O using three boundary
scan registers and inputs using one.
The ispLSI 3192 supports all IEEE 1149.1 mandatory
instructions, which include BYPASS, EXTEST and
SAMPLE.
