5M240ZT100C4N

Overview

The Altera 5M240ZT100C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX V family. It features 240 macrocells and supports up to 79 I/O pins within a 100-pin TQFP package. The device utilizes non-volatile Flash technology, enabling in-system programmability and high endurance. It operates with a core voltage of 1.8V and supports I/O voltages ranging from 1.2V to 3.3V. Key electrical characteristics include a maximum operating frequency of 200 MHz and a typical propagation delay of 5 ns. The component is designed for low power consumption, making it suitable for battery-operated applications.

Feature Summary

• Non-volatile Flash architecture allows for unlimited reprogramming and high data retention.
• Supports In-System Programmability (ISP) via JTAG or serial configuration.
• Integrated on-chip memory for user data storage and logic implementation.
• Wide I/O voltage support (1.2V, 1.5V, 1.8V, 2.5V, 3.3V) for mixed-voltage interfaces.

Applications

• Replacement for legacy GAL and EEPROM devices in industrial control systems.
• Level shifting and protocol conversion between different voltage domains.
• Address decoding and bus bridging in embedded computer architectures.
• Power-on reset generation and supervisor circuits for microprocessor systems.

Procurement Notes

Verify the suffix 'C4N' corresponds to the specific temperature grade and package variant required. Confirm that the 100-pin TQFP footprint matches the target PCB design. Ensure the Bill of Materials accounts for the 1.8V core supply requirement alongside the selected I/O voltage levels. Check for end-of-life notices as older MAX V variants may have limited production runs.

Selection Notes

Select this model when non-vatility is required without external configuration memory. Compare against EPM240 series if higher speed is needed, noting the MAX V family offers lower static power. Verify pin count requirements; the 100-pin package limits available I/Os compared to larger packages. Consider the C4N temperature range suitability for the intended operational environment.

Part Context

The 5M240ZT100C4N is part of Intel's (formerly Altera) MAX V family, which succeeded the MACH X and EPM3000 families. It is positioned as a low-cost, low-power solution for simple logic functions. The '5M' prefix denotes the MAX V family, while '240' indicates the macrocell count. This component serves as a drop-in replacement for many complex array logic devices in existing designs.

Replacement Considerations

Direct pin-to-pin replacements include the EPM240T100C5N, though timing parameters may differ. The MAX V family members like 5M240ZT144C5N offer more I/Os but require larger footprints. Verify compatibility with Quartus Prime software versions for programming support.
