LC4032C-75T48I

Overview

The LC4032C-75T48I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 32 macrocells and supports up to 32 user 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 and unlimited reprogramming cycles. The component is designed for surface-mount installation and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• 32 Macrocells with high-speed performance up to 400 MHz
• Non-volatile EEPROM memory architecture for instant-on operation
• Supports In-System Programmability (ISP) via JTAG or dedicated pins
• 48-pin Thin Quad Flat Package (TQFP) suitable for space-constrained designs

Applications

• Address decoding and bus bridging in embedded systems
• Interface translation between different logic voltage levels
• State machine implementation for control logic
• Replacement for legacy discrete logic gates in industrial equipment

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade if required, though datasheets often list 0-70C for standard variants. Confirm RoHS compliance status with the manufacturer as specifications may vary by production batch. Ensure ESD precautions are taken during handling due to CMOS sensitivity.

Selection Notes

Select this model when non-volatile storage is critical to avoid external configuration flash memories. Compare against the LC4032V series if lower power consumption is prioritized over speed, noting that the C series offers higher performance. Ensure the TQFP-48 footprint matches the PCB layout requirements.

Part Context

This part belongs to the ispMACH 4000C family, which succeeded the original ispMACH 4000 series. It provides a balance of density and speed for small-scale logic applications. The 'C' designation typically denotes the specific process generation within the 4000 family, offering improved timing characteristics over earlier versions.

Replacement Considerations

Direct pin-to-pin replacements include other members of the ispMACH 4000 family such as the LC4032V-75T48I, provided the electrical characteristics meet the design constraints. Verify that any substitute maintains the same EEPROM configuration method and I/O drive strengths.
