5M240ZT144C5N

Overview

The Altera 5M240ZT144C5N is a MAX V series CPLD featuring 240 logic elements and 192 macrocells. It operates with a single 1.8V core supply and supports MultiVolt I/O levels (1.2V, 1.5V, 1.8V, 2.5V, 3.3V). The device provides 114 user I/Os in a 144-pin TQFP package. Key electrical parameters include a maximum propagation delay of 7.5 ns and an internal oscillator. It includes 8 Kbits of user flash memory and supports In-System Programmability.

Feature Summary

• Non-volatile Flash architecture with instant-on configuration time of 0.5 ms or less
• Single 1.8V external power supply requirement for the device core
• MultiVolt I/O interface supporting 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic levels
• Integrated 8 Kbits User Flash Memory block for non-volatile data storage

Applications

• I/O expansion
• Bus and protocol bridging
• FPGA configuration
• Analog IC interface

Procurement Notes

Verify the ordering suffix 'N' indicates lead-free packaging as per the MAX V Device Handbook. Confirm the speed grade '-5' corresponds to the 7.5 ns propagation delay specification for commercial temperature range applications. Ensure the 144-TQFP package dimensions match the design footprint requirements.

Selection Notes

Select this model for designs requiring low-power, non-volatile logic with instant-on capabilities. The 5M240Z density offers 240 LEs suitable for moderate complexity logic. Verify that the 1.8V core voltage aligns with the system power budget, while checking that the selected I/O standards are compatible with the supported MultiVolt levels.

Part Context

This component belongs to the Altera MAX V family, which utilizes Flash technology to eliminate the need for external configuration devices. The 5M240Z variant sits within the mid-range density of the series, providing a balance between logic capacity and pin count for compact embedded applications.

Replacement Considerations

Vertical migration within the 144-pin TQFP package allows replacement with other MAX V devices sharing the same pinout, such as the 5M570Z, provided power pins are subsets or supersets. Cross-reference I/O pin availability using device pin-out files before substitution.
