• E2CMOS technology supporting 300 MHz operation and 3.0 ns propagation delay
• In-system programmability using IEEE 1149.1 Boundary Scan TAP
• Open-drain output option for wired-OR or bus arbitration logic

Applications

• Fast counters and state machines utilizing wide input gating
• Address decoders requiring small logic block sizes
• Flexible bus interfaces implementing wired-OR logic
• Prototyping applications allowing reprogramming of soldered devices

Procurement Notes

Verify the specific suffix 'I' against official documentation to confirm industrial temperature range specifications. Ensure compatibility with 3.3V programming environments when utilizing the Boundary Scan interface. Confirm package integrity for the LB49 variant prior to implementation.

Selection Notes

Select this component for designs requiring non-volatile reprogrammability and high-speed logic density within a 3.3V supply domain. It serves as a functional replacement for older ispLSI 2032V devices while offering improved performance metrics. Consider the open-drain capability if bidirectional bus arbitration is required.

Part Context

This part belongs to the ispLSI 2032 family of high-density programmable logic devices. It maintains pinout and functional compatibility with the standard ispLSI 2032V series but operates at lower voltage levels. The device represents an evolution in Lattice's EE CMOS technology line focused on system-level integration.

Replacement Considerations

The datasheet confirms 100% functional and pinout compatibility with ispLSI 2032V devices. Verify that the target application supports the specific timing characteristics of the VE-110 speed grade.
