LC4032B-75T44C

Overview

The LC4032B-75T44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000B family. It features 32 macrocells, 36 logic blocks, and 30 user I/O pins housed in a 44-pin TQFP package. The device supports In-System Programming (ISP) via EEPROM technology and operates within a commercial temperature range of 0°C to 90°C. Key electrical parameters include a maximum operating frequency (fMAX) of 111 MHz and a maximum propagation delay (tPD) of 7.5 ns. It requires a supply voltage between 3V and 3.6V.

Feature Summary

• ispMACH 4000B architecture with 32 macrocells and 36 logic blocks
• In-System Programmability (ISP) using non-volatile EEPROM memory
• Maximum propagation delay of 7.5 ns and fMAX of 111 MHz
• Commercial temperature range support (0°C to +90°C)

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• State machine implementation

Procurement Notes

Verify the specific suffix 'B' against the datasheet to confirm it belongs to the ispMACH 4000B series rather than the V or Z variants. Ensure the 75 speed grade corresponds to the 7.5 ns delay specification. Confirm the T44 package matches the 44-pin TQFP requirement for your PCB footprint.

Selection Notes

Select this component when a moderate density CPLD with ISP capability is required. The 32 macrocell count suits simple control logic applications. Compare against the LC4032V or LC4032Z if different speed grades or voltage levels are needed. Verify that the 111 MHz performance meets the system timing requirements.

Part Context

This part belongs to the Lattice ispMACH 4000B family, which offers high-density PLDs with fast path architectures. The family includes variants like LC4032V and LC4032Z, differentiated by speed grades and feature sets. The B-series typically denotes specific performance characteristics within the broader 4000 product line.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other LC4032 variants such as LC4032V-75TN44C or LC4032Z-75TN44C, provided their electrical specifications meet the design requirements.
