ISPLSI2032-150LT48

Overview

The ispLSI2032-150LT48 is a Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispLSI 2032A family. It features 32 macrocells and supports up to 32 I/O pins within a 48-pin Thin Quad Flat Package (TQFP). The device operates on a 5V supply voltage with a maximum operating frequency of 167 MHz and a typical propagation delay of 10 ns. It utilizes EEPROM technology for non-volatile configuration, allowing in-system programmability via the ispJTAG interface. The component is designed for commercial temperature ranges spanning 0°C to +70°C.

Feature Summary

• 32 Macrocells with 32 I/O pins in a TQFP-48 package
• Maximum operating frequency of 167 MHz with 10 ns propagation delay
• EEPROM-based non-volatile memory for reprogrammability
• Supports ispJTAG in-system programming via IEEE 1149.1

Applications

• Glue logic replacement in digital systems
• Address decoding and bus interfacing
• State machine implementation
• Simple counter and timer circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Check for moisture sensitivity level indicators on packaging, as the device requires proper handling. Confirm that the specific suffix matches the required package type and temperature range before procurement.

Selection Notes

Select this model when a moderate density CPLD with 32 macrocells is required. Ensure the design fits within the 1000 system gates limit. Verify that the 5V core voltage aligns with the system power rails. Consider the TQFP-48 footprint constraints during PCB layout planning.

Part Context

This part belongs to the ispLSI 2032A series, which offers upward compatibility with earlier ispLSI 2032 devices. It serves as a field-programmable solution bridging the gap between simple PLDs and high-density FPGAs, providing flexibility for prototyping and final production without mask costs.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the ispLSI 2032A family with different speed grades or package options. Verify functional compatibility regarding I/O drive strength and logic block architecture when substituting.
