5M1270ZF256I5N

Overview

The Altera 5M1270ZF256I5N is a MAX V series Complex Programmable Logic Device (CPLD) featuring 1,270 logic elements and 980 macrocells. It utilizes a non-volatile flash architecture for instant-on configuration with a delay of 0.5 ms or less. The device operates on a single 1.8 V core supply while supporting MultiVolt I/O levels including 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V. It offers up to 211 user I/Os in a 256-pin FineLine BGA package. Key electrical parameters include a maximum propagation delay of 6.2 ns and an internal oscillator.

Feature Summary

• Non-volatile Flash Architecture: Provides instant-on operation (≤0.5 ms) and supports up to 1,000 read/write cycles for user data storage.
• MultiVolt I/O Interface: Supports multiple voltage standards (3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V) with programmable slew rate, drive strength, and Schmitt triggers.
• High Performance: Features a maximum propagation delay of 6.2 ns and supports emulated LVDS outputs up to 304 Mbps.
• Integrated Resources: Includes an internal oscillator, four global clocks, and 8 Kbits of user flash memory.

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 'I5' corresponds to the industrial temperature range (-40°C to 100°C TJ) and speed grade 5. Confirm the 256-pin FBGA package dimensions match the design footprint requirements. Ensure compatibility with the Quartus II software version used for compilation and programming.

Selection Notes

Select this model for designs requiring low power consumption with instant-on capabilities and non-volatile storage. The -I5 speed grade is suitable for industrial environments requiring operation up to 100°C junction temperature. Compare against the -C4/C5 grades if commercial temperature ranges are sufficient, as they may offer different performance characteristics.

Part Context

This component belongs to the Altera MAX V family, which is designed for low-cost, low-power applications. It serves as a successor to older CPLD families, offering higher density per footprint and integrated flash memory. The 5M1270Z variant provides vertical migration compatibility within the 256-pin FBGA package alongside other densities like 5M570Z and 5M2210Z.

Replacement Considerations

For pin-compatible upgrades within the same package, consider the 5M570ZF256I5N (lower density) or 5M2210ZF256I5N (higher density). Verify that the target device's power pin configuration is a subset or superset of the current layout to ensure successful vertical migration without PCB redesign.
