Description

The ATF22LV10C is a high performance CMOS (Electrically Erasable) Programmable Logic Device (PLD) which utilizes Atmel’s proven electrically erasable Flash memory technology. Speeds down to 10 ns and power dissipation as low as 10 μA 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-control- led power down feature offers “zero” (5 μA 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 ATF22LV10CZ provides edge-sensing “zero” standby power (10 μA typical), as well as low voltage operation. See the ATF22LV10CZ Data Sheet.)

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 10 registers and are automatically cleared upon power up. Register Preload simplifies testing. A Security Fuse prevents unauthorized copying of programmed fuse patterns.

*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note: 1. Minimum voltage is -0.6V dc, which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is Vcc + 0.75V dc, which may overshoot to 7.0V for pulses of less than 20 ns.

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 ATF22LV10C architecture.

The ATF22LV10C has 12 inputs and 10 I/O macrocells. Each macrocell can be configured into one of four output configurations: active high/low, registered/combinatorial output. The universal architecture of the ATF22LV10C can be programmed to emulate most 24-pin PAL devices.

ATF22LV10C

Unused product terms are automatically disabled by the compiler to decrease power consumption. A Security Fuse, when programmed, protects the contents of the ATF22LV10C. 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.
