Functional Logic Diagram Description
T h e F u n c t i o n a l L o g i c D i a g r a m d e s c r i b e s t h e
ATF22V10CZ/CQZ architecture.
The ATF22V10CZ/CQZ has 12 inputs and 10 I/O macro-
cells. Each macrocell can be configured into one of four
output configurations: active high/low, registered/combina-
t o r i a l o u t p u t . T h e u n i v e r s a l a r c h i t e c t u r e o f t h e
ATF22V10CZ/CQZ can be programmed to emulate most
24-pin PAL devices.
Unused product terms are automatically disabled by the
compiler to decrease power consumption. A security fuse,
w h e n p r o g r a m m e d , p r o t e c t s t h e c o n t e n t s o f t h e
ATF22V10CZ/CQZ. Eight bytes (64 fuses) of User Signa-
ture are accessible to the user for purposes such as storing
project name, part number, revision or date. The User Sig-
nature is accessible regardless of the state of the security
fuse.
Notes:
1. Not more than one output at a time should be shorted. Duration of short circuit test should not exceed 30 sec.
