5M240ZT144I5N

Overview

The Altera 5M240ZT144I5N is a MAX V series complex programmable logic device (CPLD) featuring 240 logic elements and 192 equivalent macrocells. It utilizes non-volatile flash architecture for instant-on operation with configuration times of 0.5 ms or less. The device supports up to 114 user I/Os in a 144-pin thin quad flat pack (TQFP) package. Key electrical parameters include a maximum propagation delay of 7.5 ns, an internal oscillator, and four global clocks. It operates on a single 1.8 V core supply with multi-voltage I/O support ranging from 1.2 V to 3.3 V. The industrial temperature grade (-I5) ensures functionality within a junction temperature range of -40°C to +100°C.

Feature Summary

• Non-volatile flash architecture providing instant-on capability without external configuration memory.
• Integrated 8 Kbit user flash memory block for general-purpose data storage.
• MultiVolt I/O interface supporting voltage levels of 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
• Four global clock networks with two clocks available per logic array block.

Applications

• I/O expansion for embedded systems.
• Bus and protocol bridging between different logic families.
• FPGA configuration controller.
• Power monitoring and control circuits.

Procurement Notes

Verify the specific ordering suffix 'I5' confirms the industrial temperature rating (-40°C to +100°C) and speed grade 5. Confirm the 'T' suffix denotes the 144-pin TQFP package. Ensure compatibility with Quartus II software versions that support MAX V devices, as newer toolchains may have limited support.

Selection Notes

Select this component when low power consumption and instant-on functionality are required. The 240 LE density suits small-scale logic consolidation. Verify that the 144-pin TQFP footprint fits the board layout constraints. Consider the 7.5 ns propagation delay for timing closure in synchronous designs. Ensure the design leverages the single 1.8 V core supply to minimize power requirements.

Part Context

This part belongs to the Altera MAX V family, which offers higher density and I/Os per footprint compared to previous CPLD generations. The 5M240Z variant provides a balance of logic resources and pin count. The MAX V series is designed for cost-sensitive applications requiring non-vatile configuration and low standby current.

Replacement Considerations

Devices within the same package type and pin count, such as the 5M240ZT100 variants, may offer vertical migration capabilities if pin assignments align. Check for identical package dimensions and power pin subsets/supersets when considering alternative densities in the MAX V family.
