5M1270ZF324C4N

Overview

The Altera 5M1270ZF324C4N 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 with up to 271 user I/Os. The device operates on a single 1.8V core supply and supports MultiVolt I/O levels including 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V. Key electrical parameters include a maximum propagation delay of 6.2 ns for the -C4 speed grade and an internal oscillator. It features non-volatile flash configuration for instant-on operation and includes 8 Kbits of user-accessible flash memory.

Feature Summary

• Non-volatile architecture with instant-on configuration time of 0.5 ms or less
• Single 1.8V external power supply requirement with MultiVolt I/O support
• Integrated 8 Kbits user flash memory block for data storage
• Built-in JTAG BST circuitry compliant with IEEE Std. 1149.1-1990

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 -C4 speed grade corresponds to the commercial temperature range of 0°C to 85°C junction temperature. Ensure design layouts account for the 324-pin FBGA footprint dimensions of 19 mm x 19 mm.

Selection Notes

Select this model for designs requiring vertical migration within the 324-pin FBGA package, such as moving between 5M1270Z and 5M2210Z densities. The -C4 speed grade offers faster performance compared to the -C5 variant. Consider the 271 maximum user I/O limit when planning pin assignments for high-density interfaces.

Part Context

This component belongs to the MAX V family, which replaces older CPLD technologies with lower power consumption and higher density per footprint. The 5M1270ZF324C4N utilizes the same pinout structure as other devices in the 324-pin FBGA category, facilitating board-level upgrades without redesigning the substrate layout.

Replacement Considerations

Devices such as 5M2210ZF324C4N offer vertical migration compatibility within the same 324-pin package. Ensure that the target replacement supports the required number of logic elements and I/O pins while maintaining the same package pitch and pin definitions.
