Information
Description
The ATF16LV8CZ is a high-performance CMOS (electrically-erasable) Programmable
Logic Devices (PLDs) which utilize Atmel’s proven electrically-erasable Flash memory
technology. Speeds down to 15 ns with zero standby power dissipation are offered. All
pins offer low 10 µA leakage.

The ATF16LV8CZ provides a low-voltage and “zero” power
CMOS PLD solution with operating voltages down to 3.0V.
The ATF16LV8CZ has an edge sensing power-down
feature, offering “zero” (10 µA typical) standby power. This
feature allows the user to manage total system power to
meet specific application requirements, enhance reliability,
all without sacrificing speed. Pin “keeper” circuits on input
and output pins reduce static power consumed by pull-up
resistors.
The ATF16LV8CZ incorporates a superset of the generic
architectures, which allows direct replacement of the 16R8
family and most 20-pin combinatorial PLDs. Eight
outputs are each allocated eight product terms. Three dif-
ferent modes of operation, configured automatically with
software, allow highly complex logic functions to be
realized.

The ATF16LV8CZ is capable of operating at supply volt-
ages down to 3.0V. The ATF16LV8CZ provides edge-
sensing “zero” standby power (10 µA typical).
Functional Description
The ATF16LV8CZ macrocell can be configured in one of
three different modes. Each mode makes the
ATF16LV8CZ look like a different device. The
ATF16LV8CZ can be a registered output, combinatorial
I/O, combinatorial output, or dedicated input. Most PLD
compilers can choose the right mode automatically. The
user can also force the selection by supplying the compiler
with a mode selection. The determining factors would be
the usage of registered versus combinatorial outputs and
dedicated outputs versus outputs with output enable
control.
The universal architecture of the ATF16LV8CZ can be pro-
grammed to emulate many 20-pin PAL devices. The user
can download the subset device JEDEC programming file
to the PLD programmer, and the ATF16LV8CZ can be con-
figured to act like the chosen device.
Unused product terms are automatically disabled by the
compiler to decrease power consumption. A Security Fuse,
when programmed, protects the contents of the
ATF16LV8CZ. Eight bytes (64 fuses) of User Signature are
accessible to the user for purposes such as storing project
name, part number, revision or date. The User Signature is
accessible regardless of the state of the Security Fuse.

Using “C” Product for Industrial
To use commercial product for Industrial temperature ranges, down-grade one speed grade from the “I” to the “C” device
(7 ns “C” = 10 ns “I”) and de-rate power by 30%.
