EPM7128BFC256-7

Complex Programmable Logic Devices Overview

The Altera EPM7128BFC256-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000B family. It features 128 macrocells, 100 I/O lines, and approximately 2500 usable gates organized into 8 Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3 V (range 3.0 V to 3.6 V) with a maximum operating frequency of 243.9 MHz and a typical pin-to-pin propagation delay of 4 ns. It utilizes EEPROM technology for non-volatile configuration and is housed in a 256-pin FineLine BGA package.

Complex Programmable Logic Devices Feature Summary

• High-performance 3.3-V CMOS architecture with 4 ns max propagation delay
• In-system programmability via IEEE 1149.1 JTAG interface
• Non-volatile EEPROM configuration retaining data without external memory
• Compatible with 5.0-V and 3.3-V I/O standards

Complex Programmable Logic Devices Applications

• Data merging converters for serial-to-PCM stream processing
• Protocol conversion and interface bridging in communication systems
• Address decoding and control logic in embedded systems

Complex Programmable Logic Devices Procurement Notes

This component is designated as obsolete or end-of-life by the manufacturer. Availability is restricted to surplus markets or existing stock. Verification of RoHS compliance is required as standard production versions may not meet current environmental directives. Supply chain stability should be assessed prior to integration into new designs.

Complex Programmable Logic Devices Selection Notes

Select this model when a 3.3-V CPLD with 128 macrocells and high-speed performance (up to 243.9 MHz) is required. The FBGA-256 package suits applications needing dense I/O in a compact footprint. Ensure design requirements align with the 0°C to +70°C commercial temperature range and 3.3-V power supply constraints.

Complex Programmable Logic Devices Part Context

As part of the MAX 7000B series, the EPM7128BFC256-7 serves as a high-density solution within Altera's second-generation MAX architecture. It bridges the gap between low-density PLDs and complex FPGAs, offering deterministic timing and instant-on functionality. The 'B' suffix denotes the 3.3-V variant, distinct from the 5.0-V MAX 7000S/A families.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the MAX 7000 family include the EPM7128BFC256-10 (slower speed grade) or the EPM7256BFC256-5N (higher density, 256 macrocells). Designers migrating from 5.0-V devices should verify voltage level compatibility.
