ISPLSI2032-180LT48

Overview

The ispLSI2032-180LT48 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 2032A family, manufactured by Lattice Semiconductor Corporation. It features 32 macrocells and supports up to 32 I/O pins within a 48-pin TQFP package. The device utilizes EEPROM storage technology for non-volatile configuration. Key electrical specifications include a maximum operating frequency of 167 MHz and a typical propagation delay of 10 ns. It operates on a 5 V power supply with a voltage range of 4.75 V to 5.25 V. The component is designed for surface mount installation and functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• 32 Macrocells with 32 I/O Pins in a 48-pin TQFP package
• EEPROM-based non-volatile memory for instant-on operation
• Maximum operating frequency of 167 MHz with 10 ns propagation delay
• 5 V core voltage with TTL-compatible inputs and outputs

Applications

• Glue logic replacement in digital systems
• Address decoding and bus interfacing
• State machine implementation
• General-purpose programmable logic control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in specific datasheets, noting that some listings may vary. Check for obsolescence status, as older CPLD families may have limited availability or be discontinued. Ensure proper handling for moisture-sensitive devices during storage and reflow soldering processes.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 167 MHz speed grade suits moderate-speed applications requiring deterministic timing. Compare against the ispLSI 2032E series if higher performance (225 MHz) or mixed-voltage I/O capabilities are required. Ensure the TQFP-48 package fits the PCB footprint constraints.

Part Context

This part belongs to the ispLSI 2000 family, which introduced in-system programmability using EEPROM technology. It serves as a bridge between simple PLDs and larger FPGAs, offering high density for its class. The 'LT48' suffix denotes the low-temperature variant in a 48-pin Thin Quad Flat Package.

Replacement Considerations

Direct functional replacements include other members of the ispLSI 2032 family, such as the ispLSI 2032AE or ispLSI 2032E variants, provided pin compatibility and speed grades meet requirements. Verify package type and voltage levels before substitution.
