5M1270ZF256A5N

Overview

The Altera 5M1270ZF256A5N 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 includes an internal oscillator, up to 8 Kbits of user flash memory, and supports In-System Programming via JTAG. The component is housed in a 256-pin FineLine BGA package measuring 17 x 17 mm with a height of 1.25 mm.

Feature Summary

• Non-volatile Flash Architecture: Provides instant-on operation (≤0.5 ms) and eliminates external configuration memory requirements.
• MultiVolt I/O Interface: Supports multiple voltage standards (3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V) with a single 1.8 V core supply.
• Integrated Resources: Includes an internal oscillator, 8 Kbits of user-accessible flash memory, and four global clocks.
• High Density I/O: Offers 211 user I/O pins within a compact 256-pin FBGA footprint.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'A5N' corresponds to the automotive temperature range (-40°C to +125°C), speed grade 5, and lead-free packaging. Confirm that the 256-pin FBGA package dimensions match the design constraints. Ensure compatibility with the Quartus II software version required for MAX V device programming and compilation.

Selection Notes

Select this model for applications requiring low power consumption and instant-on functionality without external configuration devices. The -A5 suffix indicates suitability for automotive environments requiring operation up to 125°C junction temperature. Compare propagation delays against system timing requirements, noting that speed grade 5 offers lower performance than grade 4 but may offer cost advantages.

Part Context

This component belongs to the Altera MAX V family, designed as a low-cost, low-power CPLD alternative to SRAM-based FPGAs. It serves as a bridge between simple discrete logic and complex programmable devices, offering vertical migration capabilities within the same package footprint across different density levels such as 5M570Z and 5M2210Z.

Replacement Considerations

Devices within the same 256-pin FBGA package, such as the 5M570ZF256 and 5M2210ZF256, support vertical migration if pinout compatibility is verified. Ensure that the replacement part maintains the required temperature grade and speed grade specifications for the target application.
