LC4032B-25TN44C

Overview

The LC4032B-25TN44C is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000V/B/C/Z family, manufactured by Lattice Semiconductor. It features 32 macrocells and 36 logic blocks within a 44-pin Thin Quad Flat Package (TQFP). The device supports In-System Programming (ISP) via JTAG and utilizes EEPROM technology for non-volatile configuration storage. Key electrical parameters include a maximum operating frequency of 111 MHz and a propagation delay of 7.5 ns. It operates with a supply voltage range of 3.0 V to 3.6 V and supports LVCMOS 3.3/2.5/1.8 and LVTTTL I/O standards.

Feature Summary

• High-performance CPLD architecture with 32 macrocells and 36 logic blocks
• In-System Programmability (ISP) via JTAG interface using EEPROM memory
• Supports multiple I/O voltage standards including LVCMOS 3.3/2.5/1.8 and LVTTTL
• Maximum operating frequency of 111 MHz with 7.5 ns propagation delay

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• State machine implementation
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix 'TN' corresponds to the TQFP package and commercial temperature grade (0°C to 70°C or 90°C junction) as defined in the official datasheet. Confirm RoHS compliance status, as leaded versions exist within this part number series. Ensure design tools support the ispMACH 4000V/B/C/Z family for programming and verification.

Selection Notes

Select this component when a small form factor CPLD with low static power consumption is required. The 32-macrocell density is suitable for moderate complexity logic functions. Compare against the LC4032V variant if higher speed performance (up to 400 MHz) is needed, noting that the B-series offers a balance of speed and power efficiency.

Part Context

This device belongs to the ispMACH 4000V/B/C/Z family, which integrates features from previous ispLSI 2000 and ispMACH 4000A architectures. The family is characterized by its SuperFAST™ performance, global clocking capabilities, and flexible I/O structures designed for low-power applications.

Replacement Considerations

Direct functional equivalents within the same family include the LC4032V-25TN44C (higher speed) or LC4032Z-25TN44C (different voltage core). Cross-family replacements require careful review of pin compatibility and logic density.
