5M1270ZF256C5N

Overview

The Altera 5M1270ZF256C5N is a MAX V series Complex Programmable Logic Device (CPLD) housed in a 256-pin FineLine BGA package. It provides 1,270 logic elements and 980 macrocells with 211 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 and an internal oscillator. It features non-volatile flash configuration for instant-on operation and supports In-System Programming.

Feature Summary

• Non-volatile flash architecture providing instant-on configuration in 0.5 ms or less
• Single 1.8V external power supply requirement for the device core
• MultiVolt I/O interface supporting 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V logic levels
• Built-in JTAG BST circuitry compliant with IEEE Std. 1149.1-1990

Applications

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

Procurement Notes

Verify the component matches the commercial temperature grade (-C5) and lead-free packaging suffix (N). Confirm the 256-pin FBGA footprint dimensions are 17x17 mm with a 0.5 mm pitch. Ensure design files account for the specific pinout of the 5M1270Z density within this package type.

Selection Notes

Select this model for designs requiring low power consumption and non-vatile storage without external configuration memory. The -C5 speed grade offers a 6.2 ns propagation delay suitable for general-purpose logic. Verify that the target application fits within the 211 available user I/Os and 8 Kbits of user flash memory.

Part Context

This part belongs to the MAX V family, which offers vertical migration capabilities within the same package. Designers can migrate between 5M570Z, 5M1270Z, and 5M2210Z devices in the 256-pin FBGA package if dedicated pins and JTAG connections remain compatible. The Quartus II software facilitates this migration process.

Replacement Considerations

For equivalent functionality, consider other MAX V devices in the 256-pin FBGA package such as the 5M570ZF256C5N or 5M2210ZF256C5N, provided the pinout compatibility requirements for vertical migration are met.
