LC4032C-25TN48C

Overview

The LC4032C-25TN48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V/B/C/Z family manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/O pins within a TQFP-48 surface-mount package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns, while the -25 speed grade indicates a maximum propagation delay of 2.5 ns. It functions on a 3.3 V supply voltage and is rated for commercial temperatures ranging from 0°C to +90°C.

Feature Summary

• High performance with 400 MHz maximum operating frequency
• 32 macrocells with enhanced individual clock, reset, preset, and clock enable controls
• Supports in-system programming via JTAG interface
• Wide input gating capability with 36 input logic blocks

Applications

• Address decoding and bus bridging
• State machine implementation
• Fast counters and timing logic
• Interface translation between different voltage domains

Procurement Notes

Verify the specific speed grade suffix (-25 vs -75) against the required propagation delay specifications. Confirm that the TQFP-48 package matches the PCB footprint requirements. Ensure the design tool suite supports the ispMACH 4000V/B/C/Z family for configuration file generation.

Selection Notes

Select this component when a moderate density CPLD with high-speed performance is needed. The -25 variant offers faster switching than the -75 variant but may have slightly higher power consumption. Consider the 3.3 V I/O compatibility with the target system logic levels before finalizing the selection.

Part Context

This part is part of the ispMACH 4000V/B/C/Z family, which provides superfast high-density PLDs. The 'C' in the model number typically denotes the specific process technology or revision within this family, offering improved performance over previous generations like the standard ispMACH 4000 series.

Replacement Considerations

Direct replacements include other parts from the same ispMACH 4000V/B/C/Z family with equivalent pin counts and macrocell numbers, such as the LC4032V-25TN48C or LC4032Z-25TN48C, provided the specific electrical characteristics match the application requirements.
