LC4032C-10T44I

Overview

The LC4032C-10T44I is a complex programmable logic device (CPLD) from the ispMACH 4000 family, manufactured by Lattice Semiconductor Corporation. It features 32 macrocells and supports up to 36 usable I/Os within a 44-pin TQFP package. The device operates with a maximum system clock frequency of 100 MHz and includes 8 Kbits of in-system programmable flash memory for non-volatile configuration. Designed for low-power applications, it utilizes advanced CMOS technology to deliver high performance while maintaining low standby and active power consumption levels suitable for portable and battery-operated systems.

Feature Summary

• 32 Macrocells with 36 usable I/Os in a compact 44-pin TQFP package
• 8 Kbits of In-System Programmable Flash Memory for non-volatile configuration
• Maximum system clock frequency of 100 MHz
• Low-power CMOS technology with standby current as low as 2 µA

Applications

• Interface bridging between different voltage domains or protocols
• Address decoding and chip select generation in embedded systems
• State machine implementation for control logic
• Replacement for legacy GAL devices in existing designs

Procurement Notes

Verify the specific suffix 'C-10T44I' against official Lattice documentation to confirm temperature range, speed grade, and package type. Ensure compatibility with programming tools such as the ispVM System software. Check for RoHS compliance status and lead-free manufacturing details in the latest datasheet revision.

Selection Notes

Select this component when a small number of macrocells is sufficient for simple logic functions requiring non-volatile storage. Compare pin count and I/O flexibility against larger devices in the ispMACH 4000MA family if more resources are needed. Consider the TQFP package dimensions for PCB layout constraints.

Part Context

This part belongs to the ispMACH 4000 family, which bridges the gap between traditional PAL/GAL devices and modern FPGAs. It offers the ease of use of CPLDs with the reprogrammability of flash-based technologies. The family is known for deterministic timing and low power consumption, making it suitable for cost-sensitive applications.

Replacement Considerations

Direct replacements may include other parts within the ispMACH 4000 family with similar macrocell counts, such as the LC4032V series, provided pinout and electrical characteristics match. Verify that any substitute maintains the same package type and speed grade.
