in the following pages. The user can download the listed subset device JEDEC programming file
to the PLD programmer, and the ATF16V8B 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 consump-
tion. A security fuse, when programmed, protects the content of the ATF16V8B. 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.
Atmel-WinCUPL is a free tool, available on Atmel’s web site and can be used to design in all
members of the Atmel ATF16V8B family of SPLDs.

Note:
Software compilers support the three different OMC modes as different device types. Most com-
pilers 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
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.
