ISPGDX80VA-5T100

Overview

The ISPGDX80VA-5T100 is a programmable general-purpose digital crosspoint switch manufactured by Lattice Semiconductor. It features an 80 x 80 configuration, providing extensive signal routing capabilities within a single integrated circuit. The device operates on a 3.3 V supply voltage with a range of 3.0 V to 3.6 V. It utilizes Schmitt-Trigger and TTL input types alongside 3-State, Open Drain, and TTL output types. The component is housed in a TQFP-100 surface-mount package and supports operation within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Configurable as an 80 by 80 digital crosspoint matrix for flexible signal routing
• Supports mixed analog and digital signal switching applications
• Compatible with standard TTL logic levels for inputs and outputs

Applications

• Signal routing in communication systems
• Test and measurement equipment signal paths
• Industrial control system interconnects

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, and current stock status may vary significantly among suppliers. Verification of authenticity and condition is critical when sourcing from secondary markets. Designers should confirm lead times and lot dates carefully due to the discontinued status.

Selection Notes

Select this part only if an 80x80 crosspoint topology is required and form factor constraints allow for a TQFP-100 package. Verify that the 3.3V operating voltage aligns with the system power architecture. Consider the EOL status when planning long-term production lifecycles and ensure sufficient inventory is secured for maintenance or replacement needs.

Part Context

The ISPGDX80VA-5T100 belongs to the ispGDX family of programmable crosspoint switches. This series is designed to replace fixed-function multiplexers and demultiplexers, offering reconfigurable connectivity. It serves as a versatile solution for managing complex signal matrices in embedded systems where flexibility and compact integration are prioritized over high-speed serial data transmission.

Replacement Considerations

As this specific part number is discontinued, engineers must evaluate alternative crosspoint ICs from other manufacturers or newer Lattice families. Compatibility checks regarding pinout, voltage levels, and package dimensions are essential when selecting a substitute component.
