PALCE22V10 and PALCE22V10Z Families

Variable Input/Output Pin Ratio
The PALCE22V10 has twelve dedicated input lines, and each macrocell output can be an I/O pin.
Buffers for device inputs have complementary outputs to provide user-programmable input signal
polarity. Unused input pins should be tied to VCC or GND.
Registered Output Conguration
Each macrocell of the PALCE22V10 includes a D-type ip-op for data storage and
synchronization. The ip-op is loaded on the LOW-to-HIGH transition of the clock input. In the
registered conguration (S1 = 0), the array feedback is from Q of the ip-op.
Combinatorial I/O Conguration
Any macrocell can be congured as combinatorial by selecting the multiplexer path that bypasses
the ip-op (S1 = 1). In the combinatorial conguration, the feedback is from the pin.
0 = Programmed EE bit
1 = Erased (charged) EE bit
