5M240ZT144C4N

Overview

The Altera 5M240ZT144C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX V series. It features 240 logic elements and 192 macrocells, providing 114 user I/Os within a 144-pin TQFP package. The device utilizes non-volatile Flash technology for configuration, eliminating the need for external configuration memory. Key electrical parameters include a maximum propagation delay of 8.3 ns and an internal core supply voltage range of 1.71V to 1.89V. It supports In-System Programming (ISP) and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Non-volatile Flash-based architecture with no external configuration requirements
• Supports In-System Programming (ISP) for flexible field updates
• Low power consumption with 1.8V core voltage operation
• 144-pin Thin Quad Flat Package (TQFP) for compact integration

Applications

• Interface bridging between different voltage domains or protocols
• Address decoding and bus buffering in embedded systems
• Simple state machine implementation for industrial control
• Power-on reset generation and clock management circuits

Procurement Notes

Verify the speed grade suffix 'C4' corresponds to the required 8.3 ns timing specification for the target design. Confirm the operating temperature range requirement matches the commercial grade (0°C to 70°C). Ensure the 144-TQFP footprint aligns with PCB layout constraints. Check for RoHS compliance status as per current manufacturing notices.

Selection Notes

Select this component when non-volatile configuration is preferred over SRAM-based FPGAs to reduce system cost and complexity. The MAX V series is suitable for low-density logic applications requiring fewer than 240 logic elements. Consider the C4 speed grade if timing margins allow for slower switching speeds compared to higher-grade variants like C5.

Part Context

This part is part of the Intel (formerly Altera) MAX V family, designed as a low-cost alternative to traditional EPROM/OTP CPLDs. It integrates Flash memory directly on-chip, simplifying board design by removing the need for separate configuration devices often required in older CPLD architectures.

Replacement Considerations

Direct pin-to-pin replacements within the same package and logic density should be sought from the MAX V family, such as the 5M240ZT144C5N for faster timing or 5M240ZT144A4N for different packaging options. Verify that any substitute maintains the same Flash-based configuration capability.
