LC4032C-75TN48C

Overview

The LC4032C-75TN48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/B/C/Z family. It features 32 macrocells and 36 logic blocks, housed in a 48-pin TQFP package. The device supports In-System Programmability (ISP) via EEPROM technology, allowing for non-volatile configuration without removal from the circuit. It operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. The component is designed for surface-mount installation and functions within a standard voltage range.

Feature Summary

• 32 Macrocells and 36 Logic Blocks for flexible logic implementation
• In-System Programmability (ISP) using non-volatile EEPROM memory
• Maximum operating frequency of 400 MHz
• 48-pin Thin Quad Flat Package (TQFP) suitable for surface mount

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• State machine implementation
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics relative to other variants in the LC4032 series. Ensure that the design environment supports the ISP interface requirements for programming this EEPROM-based CPLD.

Selection Notes

Select this component when a moderate density of logic resources is required with the benefit of field reprogrammability. The 400 MHz performance and 7.5 ns delay make it suitable for mid-speed control applications. Compare against higher-density options like the LC4064 or LC4128 if additional macrocells are needed for future scalability.

Part Context

This part belongs to the Lattice ispMACH 4000V/B/C/Z family, which represents a generation of high-performance CPLDs. The 'C' variant typically denotes specific speed grades or manufacturing revisions within the broader LC4032 product line, sharing architectural similarities with the V and B series while offering distinct timing parameters.

Replacement Considerations

Direct pin-compatible replacements may include other speed grades within the LC4032 family, such as the LC4032V-75TN48C, provided the timing specifications meet the system requirements. Verify logical equivalence and I/O drive strengths before substitution.
