EPM7128BFC169-7

Complex Programmable Logic Devices Overview

The Altera EPM7128BFC169-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000B family. It features 128 macrocells, 2500 usable gates, and 134 I/O pins within a 169-pin FBGA package. The device operates on a 2.5 V supply voltage with a maximum frequency of 243.9 MHz and a typical propagation delay of 4 ns. It utilizes EEPROM technology for non-volatile configuration and supports In-System Programming (ISP) via the IEEE 1149.1 JTAG interface.

Complex Programmable Logic Devices Feature Summary

• MAX 7000B architecture with 2.5 V CMOS EEPROM technology
• 128 macrocells and 134 I/Os in a 169-pin FBGA package
• In-System Programmability (ISP) through built-in JTAG interface
• High performance with 4 ns max propagation delay and 243.9 MHz frequency

Complex Programmable Logic Devices Applications

• Data merging converters for serial-to-PCM stream processing
• Address decoding and interface bridging in embedded systems
• State machine implementation for industrial control logic
• Protocol handling and logic expansion in communication equipment

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to potential availability from secondary markets. Confirm RoHS compliance status as original specifications may vary by manufacturing date. Ensure proper ESD handling procedures are followed during installation, as the device exhibits moisture sensitivity. Cross-reference datasheet revisions to confirm pinout compatibility with existing PCB layouts.

Complex Programmable Logic Devices Selection Notes

Select this model when a 2.5 V supply is required instead of the standard 3.3 V or 5.0 V variants found in other MAX 7000 families. The FBGA-169 package is suitable for high-density board designs requiring 134 accessible I/O lines. Consider the 4 ns delay specification for timing-critical applications operating up to 243.9 MHz. Verify that the design toolchain supports ISP programming for the specific B variant.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B family, which introduced 2.5 V operation while maintaining pin compatibility with the 5.0 V MAX 7000S and 3.3 V MAX 7000A series. It shares the second-generation Multiple Array MatriX (MAX) architecture used across the broader MAX 7000 product line, offering a balance of density and speed for general-purpose programmable logic tasks.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives include the EPM7128BFC169-5N and EPM7128BFC169-10. These variants offer different speed grades but maintain identical electrical characteristics and package dimensions. Ensure the replacement matches the required propagation delay and operating frequency for the specific application.
