All speed ranges are specified over the 3.0V to 5.5V range for industrial and commercial temperature ranges. The ATF22LV10CZ/CQZ provides a low-voltage and edgesensing “zero” power CMOS PLD solution with “zero” standby power (5 µA typical). The ATF22LV10CZ/CQZ powers down automatically to the zero power mode through Atmel’s patented Input Transition Detection (ITD) circuitry when the device is idle. The ATF22LV10CZ/CQZ is capable of operating at supply voltages down to 3.0V. 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 “CQZ” combines this low high-frequency ICC of the “Q” design with the “Z” feature. The ATF22LV10CZ/CQZ 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. Absolute Maximum Ratings* Temperature under Bias .................................. -40°C to +85°C *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: 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.

The ATF22LV10CZ/CQZ has 12 inputs and 10 I/O macrocells. Each macrocell can be configured into one of four output configurations: active high/low or registered/combinatorial. The universal architecture of the ATF22LV10CZ/CQZ can be programmed to emulate most 24-pin PAL devices. Unused product terms are automatically disabled by the compiler to decrease power consumption. A security fuse, when programmed, protects the contents of the ATF22LV10CZ/CQZ. 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.

This parameter is only sampled and is not 100% tested. Power-up Reset Electronic Signature Word The registers in the ATF22LV10CZ/CQZ are designed to reset during power-up. At a point delayed slightly from VCC crossing V RST , all registers will be reset to the low state. The output state will depend on the polarity of the buffer. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how V CC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonic and start below 0.7V. 2. The clock must remain stable during TPR. 3. After TPR, all input and feedback setup times must be met before driving the clock pin high. There are 64 bits of programmable memory that are always available to the user, even if the device is secured. These bits can be used for user-specific data. Preload of Register Outputs The ATF22LV10CZ/CQZ’s registers are provided with circuitry to allow loading of each register with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A JEDEC file with preload is generated when a source file with vectors is compiled. Once downloaded, the JEDEC file preload sequence will be done automatically by most of the approved programmers after the programming. Security Fuse Usage A single fuse is provided to prevent unauthorized copying of the ATF22LV10CZ/CQZ fuse patterns. Once programmed, fuse verify and preload are inhibited. However, the 64-bit User Signature remains accessible. The security fuse should be programmed last, as its effect is immediate.

Parameter Description Typ Max Units TPR Power-up Reset Time 600 1000 ns VRST Power-up Reset Voltage 2.3 2.7 V 5 Input and I/O Pin Keepers All ATF22LV10CZ/CQZ family members have internal input and I/O pin-keeper circuits. Therefore, whenever inputs or I/Os are not being driven externally, they will maintain their last driven state. This ensures that all logic array inputs and device outputs are at known states. These are relatively weak active circuits that can be easily overridden by TTLcompatible drivers (see input and I/O diagrams below).
