EPM7128SQC100-15F

Complex Programmable Logic Devices Overview

The Altera EPM7128SQC100-15F is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 128 macrocells, 2,500 usable gates, and 84 user I/O pins within a 100-pin FBGA package. The device operates at 3.3V with a maximum propagation delay of 6 ns and a counter frequency of 147.1 MHz. Key architectural elements include eight logic array blocks (LABs), EEPROM-based non-volatile storage allowing up to 100 reprogramming cycles, and in-system programmability via JTAG.

Complex Programmable Logic Devices Feature Summary

• In-System Programmability (ISP): Supports programming via IEEE Std. 1149.1 JTAG interface without removing from the board.
• High Performance: Delivers 6 ns pin-to-pin delay and 147.1 MHz counter speed for high-frequency logic applications.
• Flexible Architecture: Contains 128 macrocells organized into 8 LABs with shareable and parallel expander product terms.
• Mixed-Voltage I/O: Supports MultiVolt operation, allowing interfacing with both 3.3V and 5.0V devices.

Complex Programmable Logic Devices Applications

• Replacing complex discrete logic gates and standard logic families (PALs, GALs).
• Address decoding and bus bridging in embedded systems.
• State machine implementation and timing control circuits.
• Protocol conversion and interface adaptation between different voltage domains.

Complex Programmable Logic Devices Procurement Notes

Verify the 'F' suffix indicates testing via the constant algorithm for ISP compatibility with specific in-circuit testers. Confirm the QC100 designation corresponds to the 100-pin FBGA package. Check RoHS compliance status as older variants may differ. Ensure design tools support the MAX 7000S architecture for compilation.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for the design logic density. Choose the -15 speed grade if a 6 ns delay meets timing requirements; faster grades like -10 exist but may have different availability. Verify that the FBGA package fits the PCB footprint constraints compared to PQFP or PLCC alternatives.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000S series, which adds In-System Programmability to the enhanced MAX 7000E features. It sits between the lower-density EPM7064S and higher-density EPM7160S in the family lineup. The device utilizes Altera's second-generation MAX architecture based on CMOS EEPROM technology.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible replacements within the same package include other MAX 7000S devices such as EPM7128SQC100-10 or EPM7128SQC100-15. For higher density, EPM7160S variants offer more resources. Cross-family replacement requires checking voltage levels and pin assignments against MAX 7000A or MAX V series datasheets.
