EPM7128SQC100-10

Complex Programmable Logic Devices Overview

The Altera EPM7128SQC100-10 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 128 macrocells, 8 logic array blocks (LABs), and 2,500 usable gates within a 100-pin PQFP package. The device operates at a supply voltage of 5.0 V and supports In-System Programming (ISP) via an IEEE Std. 1149.1 JTAG interface. Key electrical parameters include a maximum propagation delay of 6 ns, a maximum counter frequency of 147.1 MHz, and a fast input setup time of 3.4 ns. It utilizes CMOS EEPROM technology for non-volatile configuration.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical data may vary. Check for moisture sensitivity handling requirements prior to assembly. Ensure programming hardware compatibility with JTAG interfaces for ISP operations.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 100 I/O pins are required in a surface-mount PQFP package. Choose the -10 speed grade for applications needing a maximum propagation delay of 6 ns. Ensure the design environment supports 5.0 V logic levels and JTAG-based programming workflows.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000S series, which enhances the standard MAX 7000E architecture by adding ISP capabilities and open-drain output options. It shares architectural similarities with the EPM7128E but provides field-reprogrammability. The device represents a high-density solution within the second-generation MAX architecture line.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same speed grade include other EPM7128S variants with different package suffixes. For 3.3 V operation, consider the MAX 7000A series, though voltage level translation may be necessary.
