LC4032ZE-4MN64C

Overview

The LC4032ZE-4MN64C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000ZE family, manufactured by Lattice Semiconductor Corporation. It features 32 macrocells and supports up to 48 user I/Os within a 64-pin MiniBGA package. The device operates with a supply voltage range of 1.8V to 5.5V and offers a maximum system clock frequency of 250 MHz at the -4 speed grade. Key specifications include 1,024 bits of in-system programmable Flash memory for non-volatile configuration and support for JTAG boundary-scan testing.

Feature Summary

• ispMACH 4000ZE architecture providing 32 macrocells and high-speed performance up to 250 MHz
• In-system programmable Flash technology allowing reconfiguration without external memory
• Multi-Voltage I/O capability supporting 1.8V, 2.5V, 3.3V, and 5.5V interfaces
• 64-pin MiniBGA (6x8mm) package optimized for space-constrained designs

Applications

• Address decoding and glue logic in embedded systems
• Interface bridging between components with different voltage levels
• Power-on reset generation and supervisor circuits
• Bus buffering and protocol conversion

Procurement Notes

Verify the specific suffix codes against the manufacturer's datasheet to confirm package type, temperature range, and lead-free status. Ensure compatibility with the intended programming toolchain, such as Lattice Diamond or Radiant Software, for configuration file generation. Check for any recent product change notices regarding marking or packaging updates.

Selection Notes

Select this component when a design requires moderate logic density with fast propagation delays and multi-voltage I/O flexibility. The -4 speed grade is suitable for applications requiring clock frequencies up to 250 MHz. Consider the MiniBGA package constraints for PCB layout and thermal management if higher pin counts are needed in future revisions.

Part Context

This part belongs to the ispMACH 4000ZE series, which succeeded the original ispMACH 4000 family. The ZE variant emphasizes lower power consumption and enhanced performance compared to earlier generations. It serves as a drop-in replacement for many legacy CPLD applications while offering improved I/O drive strength and configurable output characteristics.

Replacement Considerations

Direct replacements within the same family include other members of the LC4032ZE series with different speed grades (e.g., LC4032ZE-4TN100C for larger packages). Cross-family migration to MachXO2 or CrossLink-N may require architectural redesign but offers FPGA flexibility.
