EPM7128BLC84-10

Complex Programmable Logic Devices Overview

The Altera EPM7128BLC84-10 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000B family. It features 128 macrocells, 68 I/O pins, and approximately 2500 usable gates organized into 8 Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3V with a maximum propagation delay of 10 ns and a maximum frequency of 125 MHz. It utilizes EEPROM technology for non-volatile storage and is housed in an 84-pin PLCC package.

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 handling procedures account for moisture sensitivity levels associated with the PLCC package type.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 3.3V logic compatibility with high-density programmability. Compare against MAX 7000S variants if In-System Programming (ISP) via JTAG is required, as standard MAX 7000 devices typically lack this feature. Verify pinout compatibility with existing PCB layouts using the PLCC-84 footprint.

Complex Programmable Logic Devices Part Context

This component is part of Altera's MAX 7000 series, a widely used line of CPLDs known for reliability and ease of use. The 'B' suffix indicates the 3.3V variant, distinguishing it from the 5.0V MAX 7000 and MAX 7000E families. It serves as a drop-in replacement for legacy 5V designs where voltage translation is managed externally or not required.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package are limited. Consider the EPM7128A series for similar gate counts but verify voltage differences. For ISP capabilities, evaluate the EPM7128S series, noting that pinouts and electrical characteristics may differ.
