Description

The Atmel

that utilizes the Atmel proven electrically-erasable (EE) Flash memory technology. Offered

options include speeds down to 5ns and a 100μA pin-controlled power-down mode. All

speed ranges are specified over the full 5V ± 10% range for industrial temperature ranges,

and 5V ± 5% for commercial range 5V devices.

The ATF16V8C incorporates a superset 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 auto-

matically with software, and allow highly complex logic functions to be realized.

The ATF16V8C can significantly reduce total system power, thereby enhancing system reli-

ability 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 internal pull-up resistors along with their

attendant power consumption.
