5M40ZE64C5N

Overview

The Altera 5M40ZE64C5N is a MAX V series Complex Programmable Logic Device (CPLD) featuring 40 logic elements and 32 macrocells. It utilizes non-volatile flash technology for instant-on configuration with a delay of 0.5 ms or less. The device operates on a single 1.8 V core supply and supports MultiVolt I/O levels including 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V. Key electrical parameters include a maximum propagation delay of 7.5 ns, a standby current of 25 µA, and an operating temperature range of 0°C to 85°C. It is housed in a 64-pin EQFP package.

Feature Summary

• Non-volatile Flash architecture providing instant-on operation (≤0.5 ms) and no external configuration memory requirement.
• Low power consumption with standby current as low as 25 µA and fast power-down/reset capabilities.
• MultiVolt I/O interface supporting voltage levels of 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V.
• Integrated 8 Kbit user flash memory block for general-purpose non-volatile data storage.

Applications

• I/O expansion for microprocessors and controllers.
• Bus and protocol bridging between different logic families.
• FPGA configuration controller for SRAM-based devices.
• Power monitoring and control circuits.

Procurement Notes

Verify the ordering suffix 'C' confirms the commercial temperature grade (0°C to 85°C). Confirm the 'E' indicates the Plastic Enhanced Quad Flat Pack (EQFP) package type. Ensure the 'N' suffix denotes lead-free packaging compliance. Cross-reference the specific speed grade '-5' against design timing requirements.

Selection Notes

Select this model for applications requiring low cost, low power, and non-vatile logic without external configuration chips. The 40 LE density suits simple control logic, address decoding, or glue logic. Verify that the 54 available I/O pins meet interface requirements. Consider the -5 speed grade if 7.5 ns propagation delay is sufficient for the system clock frequency.

Part Context

This component belongs to the Altera MAX V family, which offers vertical migration within packages. The 5M40Z is the lowest density device in the 64-pin EQFP footprint, sharing pinouts with higher density variants like the 5M80Z and 5M160Z for potential future upgrades without PCB redesign.

Replacement Considerations

For equivalent performance in the same package, consider the 5M40ZE64C4N for faster switching speeds or the 5M40ZE64I5N for industrial temperature ranges (-40°C to 100°C). Higher density options like the 5M80ZE64C5N are pin-compatible for migration.
