5M1270ZT144C4N

Overview

The Altera 5M1270ZT144C4N is a MAX V series Complex Programmable Logic Device (CPLD) housed in a 144-pin Thin Quad Flat Pack (TQFP). It contains 1,270 logic elements and approximately 980 equivalent macrocells. The device operates with a single 1.8 V core supply and supports MultiVolt I/O levels of 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V. It features on-chip flash storage for instant-on configuration and includes an internal oscillator. The commercial temperature grade (-C4) supports operation from 0 °C to +85 °C with a maximum propagation delay of 6.2 ns.

Feature Summary

• Non-volatile flash architecture providing instant-on configuration in 0.5 ms or less
• Single 1.8 V external power supply requirement for the device core
• MultiVolt I/O interface supporting 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V logic levels
• Integrated 8 Kbit user flash memory block for non-volatile data storage

Applications

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

Procurement Notes

Verify the ordering suffix 'C4' corresponds to the commercial temperature range (0 °C to +85 °C) and speed grade -4. Confirm the package type is TQFP with 144 pins. Ensure lead-free packaging ('N') is specified if required by assembly standards. Cross-reference the specific density code '1270Z' to confirm the 1,270 logic element count.

Selection Notes

Select this model for designs requiring low power consumption and instant-on capability without external configuration memory. The -4 speed grade offers faster performance than the -5 variant. Ensure the PCB layout accommodates the 22 mm x 22 mm TQFP footprint. Verify that the 1.8 V core voltage and selected MultiVolt I/O levels match the system requirements.

Part Context

This component belongs to the Altera MAX V family, which provides low-cost, low-power CPLD solutions. The 5M1270Z variant offers 1,270 logic elements, positioning it between the 5M570Z and 5M2210Z densities. The 'Z' suffix indicates the MAX V family signature, while 'T' denotes the TQFP package.

Replacement Considerations

Devices within the same package offering vertical migration include the 5M570ZT144 and 5M2210ZT144. These variants share dedicated and JTAG pin compatibility, allowing for density upgrades provided the power pin requirements are met.
