ISPLSI 2032A-80LTN44I

Complex Programmable Logic Devices Overview

The ispLSI 2032A-80LTN44I is an industrial-grade, in-system programmable high-density PLD manufactured by Lattice Semiconductor. It utilizes advanced 0.35 micron E2CMOS technology and features 1000 PLD gates, 32 universal I/O pins, two dedicated inputs, and three dedicated clock inputs. The device supports a maximum operating frequency of 84 MHz with a typical propagation delay of 10.0 ns. It operates on a single 5V supply and includes non-volatile reprogrammability for logic and interconnects.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 8 Generic Logic Blocks (GLBs) with 32 registers and a Global Routing Pool for complete interconnectivity.
• In-System Programmability: Supports ISP via a 5V-only interface, allowing reprogramming of soldered devices without removal.
• Non-Volatile Architecture: Built on E2CMOS technology, enabling electrically erasable and reprogrammable logic with data retention up to 20 years.
• Flexible Pin Configuration: Offers programmable output slew rate control and flexible pin placement to minimize switching noise.

Complex Programmable Logic Devices Applications

• State machine implementation for industrial control
• Fast counter applications requiring wide input gating
• Glue logic replacement in legacy system upgrades

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'TN44I' corresponds to the Lead-Free 44-Pin TQFP package and Industrial temperature grade (-40°C to +85°C). Confirm current product status as some variants in this family have been discontinued; consult official distributor channels for availability or alternative lead-free options.

Complex Programmable Logic Devices Selection Notes

Select the -80 speed grade for designs requiring a maximum toggle frequency of 84 MHz and a propagation delay of approximately 10.0 ns. Ensure the design fits within the 1000 PLD gate limit and utilizes the available 32 I/O pins. Verify that the 5V ISP programming interface is compatible with the target system's voltage levels.

Complex Programmable Logic Devices Part Context

The ispLSI 2032A is part of the ispLSI 2000A family, which is fully form and function compatible with the original ispLSI 2032 but built on an advanced 0.35 micron process. This generation offers improved performance and density while maintaining compatibility with existing designs. The 'A' suffix denotes this enhanced technology node.

Complex Programmable Logic Devices Replacement Considerations

For new designs, Lattice recommends using the ispLSI 2032E series. If replacing the 2032A, ensure the substitute maintains the 44-pin TQFP footprint and 5V ISP capability. Check for equivalent gate counts and I/O configurations in modern CPLD families if migration is required.
