LC4032V-75T48C

Overview

The LC4032V-75T48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 32 I/Os within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes non-volatile EEPROM technology for configuration, allowing for in-system programmability. The component functions on a 3.3 V supply voltage and is rated for an industrial temperature range of 0°C to +90°C.

Feature Summary

• 32 Macrocells with 36 Logic Array Blocks (LABs)
• In-system programmability via ISP interface
• Non-volatile EEPROM memory architecture
• Maximum operating frequency of 400 MHz

Applications

• General-purpose digital logic implementation
• Bus protocol conversion and bridging
• Address decoding and control logic
• State machine design

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm the commercial temperature grade (0°C to +90°C). Ensure the package designation matches the 48-lead Thin Quad Flat Package (TQFP) requirements for the target PCB layout. Confirm RoHS compliance status through the manufacturer's current product status page.

Selection Notes

Select this model when a moderate density CPLD with non-volatile storage is required. The 32 macrocell count suits simple control applications. Compare against the LC4032B series if lower cost is prioritized over speed, or the LA4032V series if automotive qualification (AEC-Q100) is necessary. Verify pin compatibility if replacing older variants.

Part Context

This part belongs to the Lattice ispMACH 4000V family, designed for high-performance, low-power applications. The 'V' indicates the voltage variant supporting 3.3 V operation. The '75' denotes the 7.5 ns speed grade. This family bridges the gap between simple PLDs and complex FPGAs, offering deterministic timing and instant-on capability due to its EEPROM structure.

Replacement Considerations

The LC4032V-75TN48C is a leaded equivalent of the LC4032V-75TQ48C. For lead-free surface mount requirements, verify the availability of the TQFP variant. Cross-reference with the LC4032B-75T48I for pin-compatible alternatives, noting differences in speed and temperature ratings.
