EPM7128STC100-15N

Complex Programmable Logic Devices Overview

The Altera EPM7128STC100-15N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 128 macrocells, 2,500 usable gates, and up to 100 user I/O pins in a TQFP-100 package. The device operates at 5.0 V with a maximum pin-to-pin propagation delay of 6 ns and a counter frequency of 147.1 MHz. Key architectural elements include eight logic array blocks (LABs), a programmable interconnect array (PIA), and EEPROM-based non-volatile configuration. It supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG interface and includes built-in boundary-scan test circuitry.

Complex Programmable Logic Devices Feature Summary

• MAX 7000S architecture with 128 macrocells and 2,500 usable gates
• In-system programming (ISP) via IEEE Std. 1149.1 JTAG interface
• Built-in JTAG boundary-scan test (BST) circuitry
• Open-drain output option available for MAX 7000S devices

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification compliant designs
• High-density integration of SSI, MSI, and LSI logic functions
• Mixed-voltage system interfacing with 3.3-V or 5.0-V devices

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm that the ordering suffix 'N' denotes lead-free status if required by specific environmental regulations. Ensure compatibility with existing design tools such as Quartus II or MAX+PLUS II for programming and verification.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 100 I/O pins are sufficient for the target logic density. The -15 speed grade provides a 6 ns delay suitable for moderate-speed applications requiring ISP capabilities. Consider alternative packages like PLCC-84 if surface-mount technology is not feasible, noting potential differences in I/O count.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000S series, which extends the standard MAX 7000E features with In-System Programmability and JTAG BST. The EPM7128 variant specifically offers a balance of logic resources and I/O density, positioned between the lower-capacity EPM7064S and higher-capacity EPM7160S within the same package family.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements within the MAX 7000S family include EPM7128STC100-10N (faster speed grade) or EPM7128ETC100-15N (non-ISP version). Verify pinout compatibility and voltage levels when substituting with other CPLD families.
