Description
The Atmel® ATF16V8C is a high performance EECMOS Programmable Logic Device
(PLD) which utilizes the Atmel proven Electrically-Erasable (EE) Flash memory
technology. Offered options include speeds down to 5ns and a 100
μ
A pin-controlled
power-down mode. All speed ranges are specified over the full 5V
±
10% range for
industrial temperature range, and 5V
±
5% for commercial range 5V devices.
The ATF16V8C incorporates a super set 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 different modes of operation
are configured automatically with software and allow highly complex logic functions to
be realized.
The ATF16V8C can significantly reduce total system power, thereby enhancing
system reliability and reducing power supply costs. When Pin 4 is configured as
the power-down control pin, supply current drops to less than 100μA whenever
the pin is high. If the power-down feature isn't required for a particular application,
Pin 4 may be used as a logic input. Also, the pin-keeper circuits eliminate the
need for external pull-up resistors along with their attendant power consumption.

3.6 Power-up Reset
Registers of the ATF16V8C are designed to reset during power-up. At a point delayed slightly from VCC crossing
VRST, 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
uncertainty of how VCC actually rises in the system, the following conditions are required:
1. The VCC rise must be monotonic, from below 0.7V.
2. After reset occurs, all input and feedback setup times must be met before driving the clock term high.
3. The signals from which the clock is derived must remain stable during tPR.

3.7 Power-down Mode
The ATF16V8C includes an optional pin controlled power-down feature. Device Pin 4 can be configured as the
power-down pin. When this feature is enabled and the power-down pin is high, total current consumption drops
to less than 100μA. In the power-down mode, all output data and internal logic states are latched and held. All
registered and combinatorial output data remains valid. Any outputs that were in a high-Z state at the onset of
power-down will remain at high-Z. During power-down, all input signals except the power-down pin are blocked.
The input and I/O pin-keeper circuits remain active to insure that pins do not float to indeterminate levels. This
helps to further reduce system power.
Selection of the power-down option is specified in the ATF16V8C logic design file. The logic compiler will
include this option selection in the otherwise standard 16V8 JEDEC fuse file. When the power-down feature is
not specified in the design file, Pin 4 is available as a logic input, and there is no power-down pin. This allows
the ATF16V8C to be programmed using any existing standard 16V8 fuse file.
Note: Some programmers list the JEDEC-compatible 16V8C (No PD used) separately from the non-JEDEC
compatible 16V8CEXT (EXT for extended features).

3.9 Output Test Loads
4. Registered Output Preload
Registers of the ATF16V8C 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 approved programmers.
5. Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF16V8C fuse patterns. Once programmed,
fuse verify and preload are inhibited; however, the 64-bit user signature remains accessible.
The security fuse will be programmed last, as its effect is immediate.

6. Input and I/O Pin-keeper Circuits
The ATF16V8C contains internal input and I/O pin-keeper circuits. These circuits allow each ATF16V8C pin to
hold its previous value even when it is not being driven by an external source or by the device’s output buffer.
This helps insure that all logic array inputs are at known, valid logic levels. This reduces system power by
preventing pins from floating to indeterminate levels. By using pin-keeper circuits rather than pull-up resistors,
there is no DC current required to hold the pins in either logic state (high or low).
These pin-keeper circuits are implemented as weak feedback inverters, as shown in the Input Diagram below.
These keeper circuits can easily be over driven by standard TTL- or CMOS-compatible drivers. The typical
overdrive current required is 40μA.

7. Functional Logic Diagram Description
The logic option and functional diagrams describe the ATF16V8C architecture. Eight configurable macrocells
can be configured as a registered output, combinatorial I/O, combinatorial output, or dedicated input.
The ATF16V8C can be configured in one of three different modes. Each mode makes the ATF16V8C look like a
different device. 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 outputs with output enable control.
The ATF16V8C universal architecture can be programmed to emulate many 20-pin PAL devices. These
architectural subsets can be found in each of the configuration modes described in the following pages. The
user can download the listed subset device JEDEC programming file to the PLD programmer, and the
ATF16V8C can be configured to act like the chosen device. Check with your programmer manufacturer for this
capability.
Unused product terms are automatically disabled by the compiler to decrease power consumption. A security
fuse, when programmed, protects the content of the ATF16V8C. 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.

8. Macrocell Configuration
Software compilers support the three different OMC 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 software 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 configured 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.
8.1 ATF16V8C 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:

16R6 16RP6
16R4 16RP4

9. ATF16V8C 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.
Combinatorial applications with an OE requirement will make the compiler select this mode. The following
devices can be emulated using this mode:
16L8
16H8
16P8
Figure 9-1. Complex Mode Option
10. ATF16V8C Simple Mode
PAL device emulation/PAL replacement. In the simple mode, eight product terms are allocated to the sum
term. Pins 15 and 16 (center macrocells) are permanently configured as combinatorial outputs. Other
macrocells can be either inputs or combinatorial outputs with 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:
10L8 10H8 10P8
