Procurement Notes

Verify the specific ordering suffix 'SU' corresponds to the 24-lead Plastic Gull Wing Small Outline (SOIC) package as defined in the manufacturer's documentation. Confirm that the '-10' speed grade aligns with the required 10ns maximum propagation delay specifications for the target design. Ensure compliance with RoHS and halide-free requirements if green package options are mandated.

Selection Notes

Select this component when a low-voltage PLD solution with programmable power-down capabilities is required. The ATF22LV10C-10SU provides flexibility through its variable product term architecture, allowing complex logic functions to be realized. Consider the 10ns propagation delay and 3.0V minimum supply voltage to ensure compatibility with system timing and power constraints.

Part Context

The ATF22LV10C series belongs to Atmel's family of high-performance CMOS electrically erasable programmable logic devices. This specific part utilizes proven electrically erasable Flash memory technology, offering reprogrammability and high reliability. The device is designed to emulate most 24-pin PAL devices while providing enhanced features such as synchronous and asynchronous reset capabilities.

Replacement Considerations

Direct replacements should maintain the 22V10 JEDEC-compatible architecture and 24-lead SOIC package. Verify that alternative components support the same 3.0V to 5.5V operating range and 10ns propagation delay. Ensure that any substitute device also offers the user-controlled power-down feature if low standby power is a critical requirement.

FAQ

What is the function of the PD pin on the ATF22LV10C?

The PD pin acts as a programmable power-down control. When active, it reduces the device supply current to less than 100µA, placing the device in a zero standby power-down mode where all output data and internal logic states are latched.

How many product terms are available per output macrocell?

Each output macrocell is allocated from 8 to 16 product terms, allowing for highly complex logic functions. Two additional product terms are included for synchronous and asynchronous reset functions.

Is the ATF22LV10C compatible with TTL inputs?

Yes, the device features CMOS and TTL compatible inputs and outputs. The inputs are also 5V tolerant, making it suitable for interfacing with various logic families.
