ISPLSI 2032A-80LTN48

Complex Programmable Logic Devices Overview

The ispLSI 2032A-80LTN48 is a high-density, in-system programmable logic device (PLD) manufactured by Lattice Semiconductor. It utilizes advanced 0.35-micron E2CMOS technology to provide non-volatile reprogrammability with 1000 PLD gates. The device features 32 universal I/O pins, two dedicated inputs, and three dedicated clock inputs within a single Megablock architecture comprising eight Generic Logic Blocks (GLBs). Designed for commercial applications, it supports a maximum operating frequency of 84 MHz and offers a typical propagation delay of 15 ns. The component operates at a supply voltage of 5V and is housed in a lead-free 48-pin Thin Quad Flat Package (TQFP).

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 1000 PLD gates, 32 macrocells, and a Global Routing Pool for complete interconnectivity.
• High Performance: Achieves up to 84 MHz maximum operating frequency with a typical propagation delay of 15 ns.
• In-System Programmability: Supports ISP via 5V-only programming, allowing reprogramming of soldered devices.
• Flexible Configuration: Features programmable output slew rate control, enhanced pin locking, and TTL-compatible I/O levels.

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital systems.
• Address decoding and bus bridging.
• State machine implementation.
• Fast counter designs utilizing wide input gating.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'TN48' corresponds to the lead-free 48-pin TQFP package variant as defined in the manufacturer's ordering guide. Confirm that the design environment supports the legacy ispLSI 2000A family architecture. Ensure compliance with RoHS standards if lead-free packaging is required for the target assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model when a non-volatile CPLD solution with 32 I/Os and 1000 gate density is required. The -80 speed grade provides an 84 MHz performance ceiling suitable for moderate-speed control logic. Verify that the application requires a 5V core voltage and does not necessitate the mixed-voltage I/O capabilities found in the subsequent ispLSI 2032E series.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which serves as an enhancement over the original ispLSI 2032 using 0.35-micron technology. It maintains full form and function compatibility with the standard 2032 series while offering improved manufacturing yields. The device represents a mature generation of PLDs designed for cost-effective, field-programmable logic solutions before the widespread adoption of FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

Lattice recommends using the ispLSI 2032E series for new designs due to its higher performance and mixed-voltage support. For direct functional replacements, verify availability of other speed grades within the 2032A family or consult authorized distributors for discontinued inventory sources.
