EPM1270GF256C3N

Complex Programmable Logic Devices Overview

The Altera EPM1270GF256C3N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 980 macrocells and 212 I/O pins within a 256-pin FineLine BGA package. The device operates at a supply voltage of 1.8 V, with an additional capability to function at 3.3 V. Key electrical parameters include a maximum operating frequency of 304 MHz and a maximum propagation delay of 6.2 ns. It utilizes Flash memory technology for non-volatile configuration, eliminating the need for external configuration devices.

Complex Programmable Logic Devices Feature Summary

• Contains 980 macrocells and 127 Logic Array Blocks (LABs) for logic implementation.
• Supports System In-Programmability (SIP) via JTAG interface.
• Operates at 1.8 V core voltage with 3.3 V tolerant I/O capabilities.
• Utilizes non-volatile Flash memory for instant-on operation without external configuration.

Complex Programmable Logic Devices Applications

• Interface bridging between different voltage domains in embedded systems.
• Address decoding and control logic in industrial automation equipment.
• State machine implementation for communication protocol handling.
• General-purpose logic expansion for microcontroller-based designs.

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status through official manufacturer documentation, as some listings indicate non-compliance while others specify detailed compliance data. Confirm the specific suffix 'N' denotes lead-free packaging and verify the humidity sensitivity level (MSL 3) requirements for storage and handling during assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires moderate logic density (980 macrocells) with a high number of I/O pins (212). The 1.8 V operation makes it suitable for low-power applications, while the 3.3 V I/O tolerance allows direct interfacing with legacy 3.3 V peripherals. Ensure the FBGA-256 package footprint fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part is part of the Altera MAX II series, which bridges the gap between simple PLDs and complex FPGAs. Unlike SRAM-based FPGAs, the MAX II series uses Flash technology, providing immediate functionality upon power-up. The EPM1270 variant represents a mid-range capacity within the family, offering a balance between pin count and logic resources for cost-sensitive designs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout include other variants from the EPM1270F256 series, such as EPM1270F256I3N or EPM1270GF256I3N, provided speed grades and temperature ranges are compatible. Cross-family replacements require careful verification of I/O counts and logic resources.
