LC4032C-75T44C

Overview

The LC4032C-75T44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 32 macrocells, 36 logic blocks, and 30 user I/O pins housed in a 44-pin TQFP package. The device utilizes EEPROM technology for non-volatile configuration and supports In-System Programming (ISP). Key electrical parameters include a maximum operating frequency of 400 MHz, a typical propagation delay of 7.5 ns, and an operating voltage range of 3.0 V to 3.6 V. It operates within a commercial temperature range of 0 °C to 90 °C.

Feature Summary

• ispMACH 4000C architecture with 32 macrocells and 36 logic blocks
• EEPROM-based non-volatile memory supporting In-System Programming
• High performance with 400 MHz max frequency and 7.5 ns propagation delay
• 30 user I/Os with independent output enable control

Applications

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

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the Commercial temperature grade variant within the ispMACH 4000C family. Ensure compatibility with standard JTAG programming interfaces for ISP functionality. Confirm package dimensions match the 10mm x 10mm TQFP footprint requirements.

Selection Notes

Select this component when a moderate density CPLD with high-speed performance (up to 400 MHz) is required. The 32 macrocell count suits applications needing up to 30 I/O lines. Verify that the 3.3V supply voltage aligns with the system design, as the device operates strictly between 3.0V and 3.6V.

Part Context

This part belongs to the Lattice ispMACH 4000C series, which succeeded the earlier ispMACH 4000A/B families. The 'C' designation typically indicates the commercial temperature grade variant. It serves as a drop-in replacement for legacy GAL devices in many industrial and consumer applications requiring reprogrammability.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LC4032B-75T44C or LC4032V-75T44C, provided the temperature grade and speed grade meet the application requirements. Verify that the alternative suffix matches the desired operating temperature range.
