Complex Programmable Logic Devices Procurement Notes

Verify the package type corresponds to the LT44 suffix, indicating a 44-pin Thin Quad Flat Package. Confirm that the design environment supports the specific programming interface required for the ispLSI family. Check for lead-free availability if environmental compliance is mandatory, as alternative suffixes exist for this device family.

Complex Programmable Logic Devices Selection Notes

Select the -100 speed grade when a 100 MHz operating frequency is sufficient, offering a balance between performance and power consumption. Ensure the design utilizes the available dedicated clock inputs if synchronous logic is required. Consider the ispLSI 1016EA for new designs, as it represents an enhanced version of this architecture with improved features.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 1016E series, which serves as a functional superset of the earlier ispLSI 1016 devices. The primary architectural addition is the global output enable pin, enhancing control over I/O states. The device is designed to replace discrete glue logic, consolidating multiple standard logic ICs into a single reconfigurable chip.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 1016EA for new designs due to its enhanced capabilities. Direct pin-to-pin replacements within the same speed grade are available, such as the -80 or -125 variants, provided timing constraints are met.

Complex Programmable Logic Devices FAQ

What is the function of the GOE 0/IN 3 pin?

The GOE 0/IN 3 pin serves a dual function. It acts as a Global Output Enable for all I/O cells when configured appropriately, or it can be used as a dedicated input pin depending on the software configuration.

How many dedicated clock inputs are available on this device?

The ispLSI 1016E-100LT44 provides three dedicated clock input pins (Y0, Y1, and Y2) that connect to the Clock Distribution Network for routing clocks to GLBs and I/O cells.

Is the device volatile or non-volatile?

The device is non-volatile. It uses Electrically Erasable and Reprogrammable memory technology, allowing it to retain its configuration without continuous power.
