P3C18V8Z35/P3C18V8ZI
DESCRIPTION
APPLICATIONS
The P3C18V8Z is a universal PAL-type device designed to operate
specifically in a low voltage environment (3.3V). Per JEDEC, the
P3C18V8Z can support a regulated operating supply voltage, 3.0 to
3.6V and an unregulated (battery) operating supply voltage, 2.7 to
3.6V, at 22 and 19 MHz, respectively. The PAL device is available in
the commercial temperature range, P3C18V8Z35, and the industrial
temperature range, P3C18V8ZI.
• Laptop, notebook and palm top computers
• Portable communications equipment
• Battery power/backed instruments
• Industrial automation/control
These devices offer virtually zero standby power (20µA typical) as
well as very low power consumption during operation (23mA worst
case in combinatorial configuration). The P3C18V8Z automatically
powers down when the inputs or the clock are idle for greater than
one full clock cycle. The device will automatically power up from a
standby mode once any input or the clock is activated. This input
transition detection circuitry makes these devices ideal for power
sensitive applications –– especially those which are battery
operated or backed up.

All the P3C18V8Z devices are available in plastic DIP, PLCC, Plastic
Small Outline (SOL), Plastic Shrink Small Outline (SSOP), and
Plastic Thin Shrink Small Outline (TSSOP) packages. A ceramic
DIP with a window for erasure is available for prototyping.
The P3C18V8Z is a two level logic element comprised of 10 inputs,
74 AND gates (logic and control product terms) and 8 Output Macro
Cells (OMCs). Each OMC can be configured as a dedicated input, a
combinatorial I/O or a registered output with internal feedback.
Each OMC has individual direction control (from the AND array) and
programmable output polarity. The dedicated clock and OE pins can
be configured as inputs for strictly combinatorial applications. Two
product terms control the asynchronous Reset and the synchronous
Preset functions.

The Philips Semiconductors’ state-of-the-art Floating-Gate CMOS
EPROM process yields bipolar equivalent performance at less than
one-quarter the power consumption. The erasable nature of the
EPROM process enables Philips Semiconductors to functionally test
the devices prior to shipment to the customer. Additionally, this
allows Philips Semiconductors to extensively stress test, as well as
ensure the threshold voltage of each individual EPROM cell. 100%
programming yield is subsequently guaranteed.

THE OUTPUT MACRO CELL (OMC)
DESIGN SECURITY
The P3C18V8Z series devices have 8 individually programmable
Output Macro Cells. The 72 AND inputs (or product terms) from the
programmable AND array are connected to the 8 OMCs in groups of
9. Eight of the AND terms are dedicated to logic functions; the ninth
is for asynchronous direction control, which enables/disables the
respective bidirectional I/O pin. Two product terms are dedicated for
the Synchronous Preset and Asynchronous Reset functions.
The P3C18V8Z series devices have a programmable security fuse
that controls the access to the data programmed in the device. By
using this programmable feature, proprietary designs implemented
in the device cannot be copied or retrieved.
Each OMC can be independently programmed via 16 architecture
control bits, AC1n and AC2n (one pair per macro cell). Similarly,
each OMC has a programmable output polarity control bit (Xn). By
configuring the pair of architecture control bits according to the
configuration cell table, 4 different configurations may be
implemented. Note that the configuration cell is automatically
programmed based on the OMC configuration.

If any one OMC is configured as registered, the configuration cell
will be automatically configured (via the design software) to ensure
that the clock and output enable functions are enabled on Pins 1
and 11, respectively. If none of the OMCs are registered, the
configuration cell will be programmed such that Pins 1 and 11 are
dedicated inputs. The programming codes are as follows:
CONFIGURATION CELL
A single configuration cell controls the functions of Pins 1 and 11.
Refer to Functional Diagram. When the configuration cell is
programmed, Pin 1 is a dedicated clock and Pin 11 is dedicated for
output enable. When the configuration cell is unprogrammed, Pins 1
and 11 are both dedicated inputs. Note that the output enable for all
registered OMCs is common—from Pin 11 only. Output enable
control of the bidirectional I/O OMCs is provided from the AND array
via the direction product term.

NOTES:
1. Stresses above those listed may cause malfunction or permanent damage to the device. This is a stress rating only. Functional operation at
these or any other condition above those indicated in the operational and programming specification of the device is not implied.
2. All digital circuits can oscillate or trigger prematurely when input rise and fall times are very long. When the input signal to a device is at or
near the switching threshold, noise on the line will be amplified and can cause oscillation which, if the frequency is low enough, can cause
subsequent stages to switch and give erroneous results. For this reason, external Schmitt-triggers are recommended if rise/fall times are
likely to exceed 200ns at VCC = 3.6V.

POWER-UP RESET
In order to facilitate state machine design and testing, a power-up
reset function has been incorporated in the P3C18V8Z. All internal
registers will reset to Active-Low (logical “0”) after a specified period
of time (tPPR). Therefore, any OMC that has been configured as a
registered output will always produce an Active-High on the
associated output pin because of the inverted output buffer. The
internal feedback (Q) of a registered OMC will also be set Low. The
programmed polarity of OMC will not affect the Active-High output
condition during a system power-up condition.

REGISTER PRELOAD FUNCTION
(DIAGNOSTIC MODE ONLY)
In order to facilitate the testing of state machine/controller designs, a
diagnostic mode register preload feature has been incorporated into
the P3C18V8Z series device. This feature enables the user to load
the registers with predetermined states while a super voltage is
applied to Pins 11 and 6 (I9/OE and I5). (See diagram for timing and
sequence.)
To read the data out, Pins 11 and 6 must be returned to normal TTL
levels. The outputs, F0 – 7, must be enabled in order to read data
out. The Q outputs of the registers will reflect data in as input via
F0 – 7 during preload. Subsequently, the register Q output via the
feedback path will reflect the data in as input via F0 – 7.
Refer to the voltage waveform for timing and voltage references.
tPL = 10µsec.

LOGIC PROGRAMMING
ERASURE CHARACTERISTICS
(For Quartz Window Packages Only)
The P3C18V8Z series is fully supported by industry standard
(JEDEC compatible) PLD CAD tools, including Philips
Semiconductors’ SNAP design software package. ABEL and
CUPL 90 design software packages also support the P3C18V8Z
architecture.
The erasure characteristics of the P3C18V8Z Series devices are
such that erasure begins to occur upon exposure to light with
wavelengths shorter than approximately 4000 Angstroms (Å). It
should be noted that sunlight and certain types of fluorescent
lighting could erase a typical P3C18V8Z in approximately three
years, while it would take approximately one week to cause erasure
when exposed to direct sunlight. If the P3C18V8Z is to be exposed
to these types of lighting conditions for extended periods of time,
opaque labels should be placed over the window to prevent
unintentional erasure.
All packages allow Boolean and state equation entry formats. SNAP,
ABEL and CUPL also accept, as input, schematic capture format.
P3C18V8Z logic designs can also be generated using the program
table entry format, which is detailed on the following pages. This
program table entry format is supported by SNAP only.
With Logic programming, the AND/OR/EX-OR gate input
connections necessary to implement the desired logic function are
coded directly from logic equations using the Program Table.
Similarly, various OMC configurations are implemented by
programming the Architecture Control bits AC1 and AC2. Note that
the configuration cell is automatically programmed based on the
OMC configuration.
The recommended erasure procedure for the P3C18V8Z is
exposure to shortwave ultraviolet light which has a wavelength of
2537 Angstroms (Å). The integrated dose (i.e., UV intensity ×
exposure time) for erasure should be a minimum of 15Wsec/cm2.
The erasure time with this dosage is approximately 30 to 35 minutes
using an ultraviolet lamp with a 12,000µW/cm2 power rating. The
device should be placed within one inch of the lamp tubes during
erasure. The maximum integrated dose a CMOS EPLD can be
exposed to without damage is 7258Wsec/cm2). Exposure of these
CMOS EPLDs to high intensity UV light for longer periods may
cause permanent damage.
In this table, the logic state of variables I, P and B associated with
each Sum Term S is assigned a symbol which results in the proper
fusing pattern of corresponding link pairs, defined as follows:
The maximum number of guaranteed erase/write cycles is 50. Data
retention exceeds 20 years.
