LC4032B-5TN48I

Overview

The LC4032B-5TN48I is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000V/B/C/Z family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/O pins in a TQFP-48 package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 2.5 ns. Designed for industrial environments, it functions within a temperature range of 0°C to +90°C and requires a 3.3 V supply voltage.

Feature Summary

• High performance with 400 MHz operating frequency and 2.5 ns propagation delay
• 32 macrocells with enhanced individual clock, reset, preset, and clock enable controls
• Industrial temperature range operation (0°C to +90°C)
• Supports In-System Programming (ISP) for flexible design updates

Applications

• Address decoding and fast counters using wide input gating
• State machine implementation with programmable global clock pins
• Interface bridging in industrial control systems

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (0°C to +90°C) compared to commercial variants. Confirm the package type is TQFP-48 and that the device is RoHS compliant. Check for current availability as lead times may vary based on manufacturer production schedules.

Selection Notes

Select this component when 32 macrocells are sufficient for logic density requirements. The 5 ns speed grade offers a balance between performance and power consumption. Ensure the design utilizes the 3.3 V supply capability and fits within the TQFP-48 footprint constraints.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which provides superfast high-density PLDs. The 'B' variant typically denotes specific performance or feature sets within this series, offering non-volatile configuration capabilities and robust I/O structures suitable for complex digital logic applications.

Replacement Considerations

Direct replacements within the same family include LC4032V-5TN48I or LC4032Z-5TN48I, provided pin compatibility and electrical specifications match the original design requirements.
