LC4032V-5T44C

Overview

The LC4032V-5T44C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V family, manufactured by Lattice Semiconductor. It features an EEPROM-based non-volatile memory architecture and provides 32 macrocells for logic implementation. The device supports In-System Programming (ISP) via JTAG and operates with a 1.8 V core voltage while maintaining 5 V tolerant I/Os. It is housed in a 44-pin Thin Quad Flat Package (TQFP) with dimensions of 10 mm x 10 mm.

Feature Summary

• ispMACH 4000V architecture with 32 macrocells and up to 30 user I/Os
• Supports LVCMOS 3.3, LVTTL, and PCI interfaces with 5 V tolerant I/Os
• JTAG In-System Programmability (ISP) using non-volatile EEPROM technology
• Global Routing Pool and Output Routing Pool for timing predictability

Applications

• General-purpose digital logic replacement
• Interface bridging between different voltage domains
• Address decoding and control logic in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix 'V' corresponds to the intended voltage and temperature grade requirements for the target application environment.

Selection Notes

Select this model when a low-power CPLD solution with 32 macrocells is required. Ensure the design utilizes the 1.8 V core supply while leveraging the 5 V tolerant I/Os for compatibility with legacy 3.3 V or 5 V peripherals.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'V' designation typically indicates the 3.3 V supply variant within this high-density PLD series.

Replacement Considerations

Compatible alternatives within the same density include other variants from the ispMACH 4000V family, such as the LC4032B or LC4032Z, provided the package and speed grades match the system requirements.
