LC4032C-5TN44C

Overview

The LC4032C-5TN44C 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 44-pin Thin Quad Flat Package (TQFP). The device supports In-System Programmability (ISP) via JTAG and utilizes non-volatile EEPROM memory for configuration retention. Electrical specifications include a maximum operating frequency of 400 MHz and a typical propagation delay of 7.5 ns for this speed grade. It operates within a commercial temperature range of 0°C to 90°C with a supply voltage of 3.3V.

Feature Summary

• ispMACH 4000 architecture with 32 macrocells and 36 logic blocks
• Non-volatile EEPROM technology enabling instant-on operation
• JTAG-based In-System Programmability (ISP)
• Global routing pool for improved timing predictability

Applications

• High-density logic replacement
• Address/data bus decoding
• Memory interface control

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the commercial temperature grade (0°C to 90°C) and 3.3V core voltage. Ensure the package type matches the 44-pin TQFP specification. Confirm that the part number corresponds to the 5 ns speed grade variant within the ispMACH 4000V series.

Selection Notes

Select this component when a low pin count CPLD with non-volatile configuration is required. The 32 macrocell capacity suits simple state machines or glue logic applications. Verify that the 44-pin TQFP footprint fits the PCB layout constraints and that the 3.3V I/O levels are compatible with the target system interfaces.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'C' suffix typically identifies the commercial temperature range variant within this family, distinct from industrial or automotive grades.

Replacement Considerations

Direct replacements within the same family include other speed grades of the LC4032C series, such as the LC4032C-7TN44C or LC4032C-10TN44C, provided the timing requirements allow for slower performance.
