5M1270ZT144C5N

Overview

The Altera 5M1270ZT144C5N is a Complex Programmable Logic Device (CPLD) belonging to the MAX V family. It provides 1,270 logic elements and 980 equivalent macrocells within a 144-pin Thin Quad Flat Pack (TQFP) package. The device operates with a single 1.8-V core supply and supports MultiVolt I/O interfaces for 3.3-V, 2.5-V, 1.8-V, 1.5-V, and 1.2-V logic levels. Key electrical specifications include a maximum propagation delay of 6.2 ns and a maximum global clock frequency of 304 MHz. It features on-chip flash storage, an internal oscillator, and instant-on configuration capabilities.

Feature Summary

• Non-volatile Flash architecture providing instant-on operation in 0.5 ms or less
• Single 1.8-V external supply requirement with MultiVolt I/O support
• Integrated User Flash Memory block of 8,192 bits for non-volatile data storage
• Built-in JTAG boundary scan circuitry compliant with IEEE Std. 1149.1-1990

Applications

• I/O expansion for embedded systems
• Bus and protocol bridging
• FPGA configuration controllers
• Power monitoring and control circuits

Procurement Notes

Verify the specific speed grade suffix 'C5' corresponds to the commercial temperature range (0°C to 85°C) and performance tier required for the design. Confirm that the 144-pin TQFP package dimensions align with the PCB footprint constraints. Ensure the design accounts for the single 1.8V core voltage requirement while managing the separate I/O supply voltages.

Selection Notes

Select this component when a low-power, non-volatile CPLD with high I/O density is needed. The 5M1270ZT144C5N offers 114 user I/O pins in a compact 22x22 mm footprint. Consider the 6.2 ns propagation delay for timing closure. Verify compatibility with the Quartus II software environment for compilation and programming.

Part Context

This part is part of the MAX V family, which succeeded earlier MAX families by integrating Flash technology directly into the CPLD structure. The '5M' prefix identifies it as a MAX V device, '1270Z' indicates the logic element count, 'T144' specifies the TQFP package, 'C' denotes commercial temperature, and '5' represents the speed grade.

Replacement Considerations

Devices within the same MAX V family sharing the 144-pin TQFP package may offer vertical migration options if pinouts are compatible. Check the manufacturer's documentation for specific migration paths between different logic densities in the same package type.
