Description
The GAL16V8, at 3.5 ns maximum propagation delay time, com-
bines a high performance CMOS process with Electrically Eras-
able (E2) floating gate technology to provide the highest speed
performance available in the PLD market. High speed erase times
(<100ms) allow the devices to be reprogrammed quickly and ef-
ficiently.
The generic architecture provides maximum design flexibility by
allowing the Output Logic Macrocell (OLMC) to be configured by
the user. An important subset of the many architecture configura-
tions possible with the GAL16V8 are the PAL architectures listed
in the table of the macrocell description section. GAL16V8 devices
are capable of emulating any of these PAL architectures with full
function/fuse map/parametric compatibility.
Unique test circuitry and reprogrammable cells allow complete AC,
DC, and functional testing during manufacture. As a result, Lattice
Semiconductor delivers 100% field programmability and function-
ality of all GAL products. In addition, 100 erase/write cycles and
data retention in excess of 20 years are specified.

The following discussion pertains to configuring the output logic
macrocell. It should be noted that actual implementation is accom-
plished by development software/hardware and is completely trans-
parent to the user.
There are three global OLMC configuration modes possible:
simple, complex, and registered. Details of each of these modes
are illustrated in the following pages. Two global bits, SYN and
AC0, control the mode configuration for all macrocells. The XOR
bit of each macrocell controls the polarity of the output in any of the
three modes, while the AC1 bit of each of the macrocells controls
the input/output configuration. These two global and 16 individ-
ual architecture bits define all possible configurations in a GAL16V8
. The information given on these architecture bits is only to give
a better understanding of the device. Compiler software will trans-
parently set these architecture bits from the pin definitions, so the
user should not need to directly manipulate these architecture bits.
The following is a list of the PAL architectures that the GAL16V8
can emulate. It also shows the OLMC mode under which the
GAL16V8 emulates the PAL architecture.

Software compilers support the three different global OLMC modes
as different device types. These device types are listed in the table
below. Most compilers have the ability to automatically select the
device type, generally based on the register usage and output
enable (OE) usage. Register usage on the device forces the soft-
ware to choose the registered mode. All combinatorial outputs with
OE controlled by the product term will force the software to choose
the complex mode. The software will choose the simple mode only
when all outputs are dedicated combinatorial without OE control.
The different device types listed in the table can be used to override
the automatic device selection by the software. For further details,
refer to the compiler software manuals.
When using compiler software to configure the device, the user
must pay special attention to the following restrictions in each mode.
In registered mode pin 1 and pin 11 are permanently configured
as clock and output enable, respectively. These pins cannot be con-
figured as dedicated inputs in the registered mode.
In complex mode pin 1 and pin 11 become dedicated inputs and
use the feedback paths of pin 19 and pin 12 respectively. Because
of this feedback path usage, pin 19 and pin 12 do not have the
feedback option in this mode.
In simple mode all feedback paths of the output pins are routed
via the adjacent pins. In doing so, the two inner most pins ( pins
15 and 16) will not have the feedback option as these pins are
always configured as dedicated combinatorial output.

In the Registered mode, macrocells are configured as dedicated
registered outputs or as I/O functions.
Architecture configurations available in this mode are similar to the
common 16R8 and 16RP4 devices with various permutations of
polarity, I/O and register placement.
All registered macrocells share common clock and output enable
control pins. Any macrocell can be configured as registered or I/
O. Up to eight registers or up to eight I/O's are possible in this mode.
Dedicated input or output functions can be implemented as sub-
sets of the I/O function.
Registered outputs have eight product terms per output. I/O's have
seven product terms per output.
The JEDEC fuse numbers, including the User Electronic Signature
(UES) fuses and the Product Term Disable (PTD) fuses, are shown
on the logic diagram on the following page.

In the Complex mode, macrocells are configured as output only or
I/O functions.
Architecture configurations available in this mode are similar to the
common 16L8 and 16P8 devices with programmable polarity in
each macrocell.
Up to six I/O's are possible in this mode. Dedicated inputs or
outputs can be implemented as subsets of the I/O function. The
two outer most macrocells (pins 12 & 19) do not have input capa-
bility. Designs requiring eight I/O's can be implemented in the
Registered mode.
All macrocells have seven product terms per output. One product
term is used for programmable output enable control. Pins 1 and
11 are always available as data inputs into the AND array.

In the Simple mode, macrocells are configured as dedicated inputs
or as dedicated, always active, combinatorial outputs.
Architecture configurations available in this mode are similar to the
common 10L8 and 12P6 devices with many permutations of ge-
neric output polarity or input choices.
All outputs in the simple mode have a maximum of eight product
terms that can control the logic. In addition, each output has pro-
grammable polarity.
Pins 1 and 11 are always available as data inputs into the AND
array. The center two macrocells (pins 15 & 16) cannot be used
as input or I/O pins, and are only available as dedicated outputs.
The JEDEC fuse numbers including the UES fuses and PTD fuses
are shown on the logic diagram.

fmax with Internal Feedback 1/(tsu+tcf)
Note: tcf is a calculated value, derived by subtracting tsu from
the period of fmax w/internal feedback (tcf = 1/fmax - tsu). The
value of tcf is used primarily when calculating the delay from
clocking a register to a combinatorial output (through registered
feedback), as shown above. For example, the timing from clock
to a combinatorial output is equal to tcf + tpd.
fmax with External Feedback 1/(tsu+tco)
Note: fmax with external feedback is calculated from measured
tsu and tco.
fmax with No Feedback
Note: fmax with no feedback may be less than 1/(twh + twl). This
is to allow for a clock duty cycle of other than 50%.

Electronic Signature
An electronic signature is provided in every GAL16V8 device. It
contains 64 bits of reprogrammable memory that can contain user
defined data. Some uses include user ID codes, revision numbers,
or inventory control. The signature data is always available to the
user independent of the state of the security cell.
NOTE: The electronic signature is included in checksum calcula-
tions. Changing the electronic signature will alter the checksum.
Security Cell
A security cell is provided in the GAL16V8 devices to prevent un-
authorized copying of the array patterns. Once programmed, this
cell prevents further read access to the functional bits in the device.
This cell can only be erased by re-programming the device, so the
original configuration can never be examined once this cell is pro-
grammed. The Electronic Signature is always available to the user,
regardless of the state of this control cell.
Latch-Up Protection
GAL16V8 devices are designed with an on-board charge pump
to negatively bias the substrate. The negative bias minimizes the
potential of latch-up caused by negative input undershoots. Ad-
ditionally, outputs are designed with n-channel pull-ups instead of
the traditional p-channel pull-ups in order to eliminate latch-up due
to output overshoots.
Device Programming
GAL devices are programmed using a Lattice Semiconductor-
approved Logic Programmer, available from a number of manu-
facturers. Complete programming of the device takes only a few
seconds. Erasing of the device is transparent to the user, and is
done automatically as part of the programming cycle.

Switching Test Conditions (Continued)
Output Register Preload
When testing state machine designs, all possible states and state
transitions must be verified in the design, not just those required
in the normal machine operations. This is because, in system
operation, certain events occur that may throw the logic into an
illegal state (power-up, line voltage glitches, brown-outs, etc.). To
test a design for proper treatment of these conditions, a way must
be provided to break the feedback paths, and force any desired (i.e.,
illegal) state into the registers. Then the machine can be sequenced
and the outputs tested for correct next state conditions.
GAL16V8 devices include circuitry that allows each registered
output to be synchronously set either high or low. Thus, any present
state condition can be forced for test sequencing. If necessary,
approved GAL programmers capable of executing text vectors
perform output register preload automatically.
Input Buffers
GAL16V8 devices are designed with TTL level compatible input
buffers. These buffers have a characteristically high impedance,
and present a much lighter load to the driving logic than bipolar TTL
devices.
The GAL16V8 input and I/O pins have built-in active pull-ups. As
a result, unused inputs and I/O's will float to a TTL "high" (logical
"1"). Lattice Semiconductor recommends that all unused inputs
and tri-stated I/O pins be connected to another active input, VCC,
or Ground. Doing this will tend to improve noise immunity and re-
duce ICC for the device.

INPUT/OUTPUT EQUIVALENT SCHEMATICS
Circuitry within the GAL16V8 provides a reset signal to all reg-
isters during power-up. All internal registers will have their Q
outputs set low after a specified time (tpr, 1μs MAX). As a result,
the state on the registered output pins (if they are enabled) will
always be high on power-up, regardless of the programmed
polarity of the output pins. This feature can greatly simplify state
machine design by providing a known state on power-up. Be-
cause of the asynchronous nature of system power-up, some

conditions must be met to provide a valid power-up reset of the
device. First, the VCC rise must be monotonic. Second, the clock
input must be at static TTL level as shown in the diagram during
power up. The registers will reset within a maximum of tpr time.
As in normal system operation, avoid clocking the device until all
input and feedback path setup times have been met. The clock
must also meet the minimum pulse width requirements.
