LC4032C-5TN48I

Overview

The LC4032C-5TN48I is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000C family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/Os in a TQFP-48 package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 5 ns. It functions within a supply voltage range of 2.7 V to 3.6 V and an industrial temperature range of -40°C to +85°C.

Feature Summary

• ispMACH 4000C architecture with 32 macrocells
• High-speed performance: 400 MHz max frequency, 5 ns typical delay
• Industrial temperature grade (-40°C to +85°C)
• TQFP-48 surface-mount package

Applications

• Interface bridging between different logic families
• Address decoding and control logic
• State machine implementation
• Bus buffering and protocol conversion

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the package type is TQFP-48. Check for RoHS compliance status on the current datasheet. Ensure the ordering part number matches LC4032C-5TN48I exactly to avoid variant mismatches.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic. The 5 ns delay suits moderate-speed applications requiring deterministic timing. Compare against the LC4032V series if lower power consumption is critical, or the LC4032B series if cost optimization is the primary driver over speed.

Part Context

This component belongs to the ispMACH 4000C family, which succeeded the original ispMACH 4000A/B series. The 'C' designation indicates the specific generation within the 4000 line, offering improved speed grades compared to earlier variants while maintaining pin compatibility with some legacy designs.

Replacement Considerations

Direct pin-compatible replacements include other members of the LC4032 family such as LC4032V-5TN48I or LC4032B-5TN48I, provided their electrical characteristics meet the system requirements. Verify timing parameters and voltage ranges before substitution.
