5M1270ZF256C4N

Overview

The Altera 5M1270ZF256C4N 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 equivalent macrocells with 211 user I/Os. The device operates on a single 1.8V core supply and supports MultiVolt I/O levels of 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V. Key electrical parameters include a maximum propagation delay of 6.2 ns and a maximum global clock frequency of 304 MHz. It features non-volatile flash configuration for instant-on operation and an operating temperature range of 0°C to +85°C.

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
• Integrated 8 Kbits user flash memory block for general-purpose storage

Applications

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

Procurement Notes

Verify the specific ordering suffix 'C4' corresponds to the commercial temperature grade (-0°C to +85°C) and speed grade -4 (6.2 ns delay). Confirm the package type is 256-pin FBGA with dimensions 17 x 17 mm. Ensure compatibility with Quartus II software for compilation and programming.

Selection Notes

Select this model for designs requiring low power consumption and non-volatile logic without external configuration memory. The 5M1270Z offers vertical migration capability within the 256-pin FBGA package to other densities like 5M570Z or 5M2210Z if pinout constraints allow. Verify that the 6.2 ns propagation delay meets the timing requirements for the target application.

Part Context

This component belongs to the Altera MAX V family, which is designed as a low-cost, low-power CPLD solution. The '5M' prefix identifies it as a MAX V device, while '1270Z' indicates the 1,270 logic element density. The 'F' denotes the FineLine BGA package, and '256' specifies the pin count.

Replacement Considerations

Within the same 256-pin FBGA package, the 5M570ZF256C4N and 5M2210ZF256C4N offer vertical migration options. These devices share dedicated and JTAG pins, allowing for potential footprint reuse if power and I/O pin counts are sufficient.
