Description

The Atmel? ATF22LV10C is a high-performance CMOS (electrically erasable) programmable logic device (PLD) that utilizes the Atmel proven electrically erasable Flash memory technology. Speeds down to 10ns and power dissipation as low as 10mA are offered. All speed ranges are specified over the 3.0V to 5.5V range for industrial and commercial temperature ranges.

The ATF22LV10C provides a low-voltage and user controlled “zero” power CMOS PLD solution. A user-controlled power-down feature offers “zero” (10μA typical) standby power. This feature allows the user to manage total system power to meet specific application requirements and enhance reliability, all without sacrificing speed. (The Atmel ATF22LV10CQZ provides edge-sensing “zero” standby power (3μA typical), as well as low voltage operation. See the ATF22LV10CQZ datasheet.)

The ATF22LV10C is capable of operating at supply voltages down to 3.0V. When the power-down pin is active, the device is placed into a zero standby power-down mode. When the power-down pin is not used or active, the device operates in a full power low voltage mode. Pin “keeper” circuits on input and output pins hold pins to their previous logic levels when idle, which eliminate static power consumed by pull-up resistors.

The ATF22LV10C macrocell incorporates a variable product term architecture. Each output is allocated from 8 to 16 product terms which allows highly-complex logic functions to be realized. Two additional product terms are included to provide synchronous reset and asynchronous reset. These additional product terms are common to all ten registers and are automatically cleared upon power-up. Register preload simplifies testing. A security fuse prevents unauthorized copying of programmed fuse patterns.
