Block Diagram

Description

The ATF20V8C is a high-performance CMOS (electrically
erasable) programmable logic device (PLD) that utilizes
Atmel’s proven electrically erasable technology. Speeds
down to 5 ns and power dissipation as low as 10 µA are
offered. All speed ranges are specified over the full 5V ±
10% range for industrial temperature ranges, and 5V ± 5%
for commercial ranges.

The ATF20V8C(Q) provides a high-speed CMOS PLD
solution with maximum pin-to-pin delay of 5 ns. The
ATF20V8C(Q) also has a user-controlled power-down fea­ture, offering “zero” standby power (10 µA typical). The
user-controlled power-down feature allows the user to
manage total system power to meet specific application
requirements and enhance reliability without sacrificing
speed.

The ATF20V8CQZ provides the zero power CMOS PLD
solution, with “zero” standby power (10 µA typical). The
device powers down automatically through Atmel’s pat­ented Input Transition Detection (ITD) circuitry to the “zero”
standby power mode when all inputs are idle.

Pin “keeper” circuits on input and output pins reduce static
power consumed by pull-ups.

The ATF20V8C(Q)(Z) is the industry-standard 20V8 archi­tecture. Eight outputs are each allocated eight product
terms. Three different modes of operation, configured auto­matically with software, allow highly complex logic
functions to be realized.

Preload of Registered Outputs

The ATF20V8C registers are provided with circuitry to
allow loading of each register with either a high or a low.
This feature will simplify testing since any state can be
forced into the registers to control test sequencing. A
JEDEC file with preload is generated when a source file
with vectors is compiled. Once downloaded, the JEDEC file
preload sequence will be done automatically by most of the
approved programmers after the programming.

The registers in the ATF20V8Cs are designed to reset dur­ing power-up. At a point delayed slightly from V

, all registers will be reset to the low state. As a result,

the registered output state will always be high on power-up.

This feature is critical for state machine initialization. How­ever, due to the asynchronous nature of reset and the

Electronic Signature Word

There are 64 bits of programmable memory that are always
available to the user, even if the device is secured. These
bits can be used for user-specific data.

Security Fuse Usage

A single fuse is provided to prevent unauthorized copying
of the ATF20V8C’s fuse patterns. Once programmed, fuse
verify and preload are inhibited. However, the 64-bit User
Signature remains accessible.

The security fuse should be programmed last, as its effect
is immediate.

Programming/Erasing

Programming/erasing is performed using standard PLD
programmers. For further information, see the Configurable

Logic data book section titled, “CMOS PLD Programming
Hardware and Software Support.”

Input and I/O Pull-ups

All ATF20V8C family members have internal input and I/O
“pin-keeper” circuits. Therefore, whenever inputs or I/Os
are not being driven externally, they will maintain their last
driven state. This ensures that all logic array inputs and
device outputs are at known states. These are relatively
weak active circuits that can be easily overridden by TTL­compatible drivers (see input and I/O diagrams below).

Functional Logic Diagram Description

The logic option and functional diagrams describe the
ATF20V8C architecture. Eight configurable macrocells can
be configured as a registered output, combinatorial I/O,
combinatorial output or dedicated input.

The ATF20V8C’s macrocell can be configured in one of
three different modes. Each mode makes the ATF20V8Cs
look like a different device. The ATF20V8Cs 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 register versus
combinatorial outputs and dedicated outputs versus output
with output enable control.

The ATF20V8Cs have a user-controlled power-down pin,
which, when active, allows the user to place the device into

operate at high speed. Maximum pin-to-pin delays of 5 ns
are offered. Static power loss due to pull-up resistors is
eliminated by using input and output pin “keeper” circuits
that hold pins to their previous logic levels when idle.

The universal architecture of the ATF20V8Cs can be pro­grammed to emulate many 24-pin PAL devices. The user
can download the subset device JEDEC programming file
to the PLD programmer and the ATF20V8Cs can be config­ured 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 the ATF20V8Cs.
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.

Registered Mode

PAL Device Emulation/PAL Replacement

The registered mode is used if one or more registers are
required. Each macrocell can be configured as either a reg­istered or combinatorial output or I/O, or as an input. For a
registered output or I/O, the output is enabled by the OE
pin, and the register is clocked by the CLK pin. Eight prod­uct terms are allocated to the sum term. For a combinato­rial output or I/O, the output enable is controlled by a
product term, and seven product terms are allocated to the

sum term. When the macrocell is configured as an input,
the output enable is permanently disabled.

Any register usage will make the compiler select this mode.
The following registered devices can be emulated using
this mode:

Complex Mode

PAL Device Emulation/PAL Replacement

In the Complex Mode, combinatorial output and I/O func­tions are possible. Pins 1 and 11 are regular inputs to the
array. Pins 13 through 18 have pin feedback paths back to
the AND-array, which makes full I/O capability possible.
Pins 12 and 19 (outermost macrocells) are outputs only.
They do not have input capability. In this mode, each
macrocell has seven product terms going to the sum term
and one product term enabling the output.

Complex Mode Operation

In the Simple Mode, eight product terms are allocated to

pin feedback to the AND-array. Pins 1 and 11 are regular
inputs.

The compiler selects this mode when all outputs are combi­natorial without OE control. The following simple PALs can
be emulated using this mode:
