5M1270ZF324C5N

Overview

The Altera 5M1270ZF324C5N is a MAX V series Complex Programmable Logic Device (CPLD) housed in a 324-pin FineLine BGA package. It provides 1,270 logic elements and 980 equivalent macrocells, supporting up to 271 user I/Os. The device operates with a core voltage of 1.8 V and supports MultiVolt I/O levels including 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V. 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 for instant-on configuration and non-volatile user data.

Feature Summary

• Non-volatile architecture with instant-on configuration time of 0.5 ms or less
• Integrated 8 Kbits User Flash Memory (UFM) for general-purpose storage
• MultiVolt I/O interface supporting 3.3-V, 2.5-V, 1.8-V, 1.5-V, and 1.2-V logic levels
• Internal oscillator and four global clocks for efficient clock distribution

Applications

• I/O expansion and bus bridging
• FPGA configuration controllers
• Power monitoring and control systems
• Analog IC interface circuits

Procurement Notes

Verify the specific ordering suffix 'N' indicates lead-free packaging as defined in the MAX V Device Handbook. Confirm that the 324-pin FBGA package dimensions match the target PCB footprint requirements. Ensure design layouts account for the vertical migration capabilities within the same package family if density upgrades are planned.

Selection Notes

Select this model for designs requiring high I/O density (up to 271 pins) within a single CPLD. The 6.2 ns speed grade (-5) offers lower performance than the -4 grade but may provide cost benefits. Verify that the 1.8 V core supply and selected MultiVolt I/O standards align with the system's power budget and signal integrity requirements.

Part Context

This component belongs to the MAX V family, which replaces traditional SRAM-based CPLDs with non-volatile flash technology. The 5M1270Z variant sits between the 5M570Z and 5M2210Z densities. It shares pin compatibility with other devices in the 324-pin FBGA package, allowing for vertical migration during product lifecycle management.

Replacement Considerations

Devices such as 5M570ZF324C5N and 5M2210ZF324C5N offer vertical migration within the 324-pin FBGA package. Substitution requires verifying that the target device has sufficient logic resources and that the pinout remains compatible with the existing board layout.
