Description

The ATF22V10CZ is a high performance CMOS (Electrically Erasable) Programmable Logic Device (PLD) which utilizes Atmel’s proven electrically erasable Flash memory technology. Speeds down to 12 ns with zero standby power dissipation are offered. All speed ranges are specified over the full 5V ±10% range for industrial temperature ranges; 5V ± 5% for commercial range 5-volt devices.

The ATF22V10CZ provides a “zero” power CMOS PLD solution with 5V operating voltages. The ATF22V10CZ powers down automatically to the zero power mode through Atmel’s patented Input Transition Detection (ITD) circuitry when the device is idle. The ATF22V10CZ has an edge-sensing power down feature, offering “zero” (25 μA worst case) standby power. This feature allows the user to manage total system power to meet specific application requirements and enhance reliability. Pin “keeper”

circuits on input and output pins eliminate static power consumed by pull-up resistors.

The ATF22V10CZ incorporates a superset of the generic architectures, which allows direct replacement of the 22V10 family and most 24-pin combinatorial PLDs. Ten outputs are each allocated 8 to 16 product terms. Three different modes of operation, configured automatically with software, allow highly complex logic functions to be realized.

*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.

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 architecture.

The ATF22V10CZ 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 ATF22V10CZ can be programmed to emulate most 24-pin PAL devices.

DC Characteristics

Unused product terms are automatically disabled by the compiler to decrease power consumption. A Security Fuse, when programmed, protects the contents of the ATF22V10CZ. 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.
