• In-system programmability via IEEE 1149.1 JTAG test access port.
• User-selectable 3.3V or 5V I/O voltage levels for mixed-voltage systems.
• Programmable open-drain output option and slew rate control.

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital circuits.
• Address decoding and state machine implementation.
• Mixed-voltage interface bridging between 3.3V and 5V components.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade (-125) and package type (J44 PLCC) against design requirements. Confirm that the commercial temperature range (0°C to +70°C) meets operational needs. Ensure programming tools support the ispLSI 1016EA family for configuration.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring moderate density with flexible I/O voltage levels. The -125 speed grade provides a balance between performance and power consumption. Consider the -200 variant if higher frequencies are needed, or the -100 for lower power applications.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 1000EA series, which enhances the original ispLSI 1016E by adding user-selectable I/O voltages and open-drain outputs. It is functionally compatible with the earlier ispLSI 1016E while offering improved flexibility for modern mixed-signal environments.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 1016EA-125LT44 serves as a direct pin-compatible alternative in a TQFP package. For new 5V designs, Lattice recommends using the ispMACH 4A5 family instead.
