ISPLSI2032-80LT48I

Overview

The ISPLSI2032-80LT48I is a Complex Programmable Logic Device (CPLD) from the ispLSI 2000 family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/O pins within a 48-pin Thin Quad Flat Package (TQFP). The device utilizes EEPROM technology for non-volatile configuration and operates on a 5V power supply with a voltage range of 4.75V to 5.25V. It offers a maximum operating frequency of 167 MHz and a typical propagation delay of 10 ns. Designed for commercial applications, it functions within a temperature range of 0°C to +70°C.

Feature Summary

• 32 Macrocells with 32 I/O Pins
• EEPROM Non-Volatile Memory Technology
• 167 MHz Maximum Operating Frequency
• 48-Pin TQFP Surface Mount Package

Applications

• General-purpose glue logic replacement
• Address decoding and bus interfacing
• State machine implementation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as legacy variants may differ. Check for moisture sensitivity level requirements during storage and handling. Ensure design-in documentation matches the specific -80 speed grade and LT48 package variant.

Selection Notes

Select this model when 32 macrocells are sufficient for the logic density requirements. The -80 speed grade provides a balance between performance and power consumption. The LT48 package is suitable for standard surface mount assembly processes. Consider the ispLSI 2032A series if higher speed grades or updated manufacturing processes are required.

Part Context

This component belongs to the ispLSI 2000 family, which introduced in-system programmability using ISPJTAG. It serves as a bridge between discrete logic gates and larger FPGA solutions, offering field-reprogrammability without the complexity of gate arrays. The family is known for high reliability and ease of use in embedded control applications.

Replacement Considerations

Direct pin-to-pin replacements include other speed grades within the same package, such as the ISPLSI2032-100LT48I or ISPLSI2032-150LT48I, provided timing constraints allow. Upgrades to the ispLSI 2032A series offer functional compatibility with improved performance characteristics.
