5M240ZM68C5N

Overview

The Altera 5M240ZM68C5N is a Complex Programmable Logic Device (CPLD) belonging to the MAX V series. It features 240 logic elements and 192 macrocells, providing 52 user I/O pins. The device utilizes non-volatile Flash technology for configuration, supporting In-System Programmability (ISP). Key electrical specifications include a maximum propagation delay of 7.5 ns and an internal core supply voltage range of 1.71V to 1.89V. It is housed in a 68-TFBGA package with dimensions of 5x5 mm and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Non-volatile Flash-based architecture eliminates the need for external configuration memory.
• Supports In-System Programmability (ISP) for flexible field updates.
• Low power consumption with 1.8V core voltage operation.
• High-density logic with 240 logic elements and 192 macrocells.

Applications

• Interface bridging between different voltage domains or protocols.
• Address decoding and chip select generation in embedded systems.
• Simple state machine implementation for control logic.
• Level shifting and buffer applications.

Procurement Notes

Verify the specific speed grade suffix 'C5' against the required timing constraints, as it denotes a 7.5 ns maximum delay. Confirm the 68-TFBGA package availability and ensure the supplier provides original manufacturer documentation. Check for RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling.

Selection Notes

Select this component when a non-volatile CPLD with moderate density (240 LEs) is required without external configuration flash. Compare the 7.5 ns delay against system clock requirements. Ensure the design fits within 192 macrocells and 52 I/O pins. Consider the 0°C to 70°C operating range; if industrial temperatures are needed, verify if a higher temperature variant exists within the MAX V family.

Part Context

This part belongs to the Intel (formerly Altera) MAX V family, which uses Flash technology for instant-on capability. It serves as a low-cost, low-power alternative to SRAM-based FPGAs for fixed logic functions. The 'Z' in the part number typically indicates the Flash-based MAX V series, while 'M68' specifies the 68-pin package type.

Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade may be limited. Other MAX V devices with similar logic counts (e.g., 5M1270) might require schematic changes due to different pinouts or I/O counts. Verify compatibility with existing programming tools like Quartus Prime Lite.
