5M1270ZT144I5N

Overview

The Altera 5M1270ZT144I5N is a MAX V series Complex Programmable Logic Device (CPLD) housed in a 144-pin Thin Quad Flat Pack (TQFP). It provides 1,270 logic elements and 980 equivalent macrocells with 114 user I/O pins. The device operates at an internal core voltage of 1.8V and supports MultiVolt I/O levels including 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V. Key electrical specifications include a maximum propagation delay of 6.2 ns and a maximum global clock frequency of 304 MHz. It features industrial temperature range operation from -40°C to 100°C junction temperature.

Feature Summary

• Non-volatile flash architecture providing instant-on configuration in 0.5 ms or less
• Integrated 8 Kbits User Flash Memory (UFM) for general-purpose data storage
• Supports In-System Programming (ISP) and JTAG boundary scan compliance
• MultiVolt I/O interface compatible with 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V standards

Applications

• Bus and protocol bridging
• FPGA configuration controllers
• Power monitoring and control systems
• Analog IC interface circuits

Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature range (-40°C to 100°C TJ) and '5N' indicates lead-free packaging. Confirm the package type 'T' corresponds to the 144-pin TQFP form factor. Ensure compatibility with the Quartus II software platform for design compilation and programming.

Selection Notes

Select this model for designs requiring non-vatile logic with low standby current (as low as 25 µA). The 144-pin TQFP package offers vertical migration capability within the MAX V family for densities such as 5M570Z and 5M2210Z if pinout constraints allow. Consider the 6.2 ns speed grade for timing-critical applications compared to slower commercial variants.

Part Context

This component belongs to the MAX V family, which integrates on-chip flash storage and an internal oscillator to reduce external component count. The 5M1270Z variant represents a mid-to-high density option within the 144-pin package lineup, offering 1,270 LEs. It is designed to replace legacy SRAM-based CPLDs by eliminating the need for external configuration memory.

Replacement Considerations

Devices sharing the same 144-pin TQFP footprint and pinout for vertical migration include the 5M570ZT144 and 5M2210ZT144 series. Verify that power pin requirements are met when migrating to higher density devices, as larger densities may require additional power pins.
