Speeds down to 7.5 ns and power dissipation as low as 10 mA are offered. All speed ranges are specified over the full 5V ± 10% range for military and industrial tempera- ture ranges, and 5V ± 5% for commercial temperature ranges. Several low power options allow selection of the best solution for various types of power-limited applications. Each of these options significantly reduces total system power and enhances system reliability.

Typical values for nominal supply voltage. This parameter is only sampled and is not 100% tested. Power Up Reset The registers in the ATF22V10Bs are designed to reset during power up. At a point delayed slightly from V CC crossing V RST , all registers will be reset to the low state. The output state will depend on the polarity of the output buffer. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how VCC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonic, 2. After reset occurs, all input and feedback setup times must be met before driving the clock pin high, and 3. The clock must remain stable during tPR. Preload of Registered Outputs The ATF22V10B’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. Parameter Description Typ Max Units tPR Power-Up Reset Time 600 1,000 ns VRST Power-Up Reset Voltage 3.8 4.5 V Security Fuse Usage A single fuse is provided to prevent unauthorized copying of the ATF22V10B 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. 5 Electronic Signature Word Input and I/O Pull-Ups 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. All ATF22V10B family members have internal input and I/O pull-up resistors. Therefore, whenever inputs or I/Os are not being driven externally, they will float to V CC . This ensures that all logic array inputs are at known states. These are relatively weak active pull-ups that can easily be overdriven by TTL-compatible drivers (see input and I/O diagrams below). Programming/Erasing Programming/erasing is performed using standard PLD programmers. See CMOS PLD Programming Hardware and Software Support for information on software/programming.
