EPM7128SLC84-10N

Complex Programmable Logic Devices Overview

The EPM7128SLC84-10N is a high-density, high-performance Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. Fabricated using CMOS EEPROM technology, it integrates 128 macrocells organized into eight logic array blocks (LABs), providing approximately 2,500 usable gates. The device supports in-system programmability (ISP) via a built-in IEEE Std. 1149.1 JTAG interface and includes boundary-scan test circuitry. It operates at a maximum frequency of 147.1 MHz with a pin-to-pin propagation delay of 6 ns. The component is housed in an 84-pin PLCC package and offers multi-voltage I/O capabilities for interfacing with both 3.3-V and 5.0-V logic systems.

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via 4-pin JTAG interface compatible with IEEE Std. 1149.1 and IEEE Std. 1532
• Integrated JTAG boundary-scan test (BST) circuitry for devices with 128 or more macrocells
• MultiVolt I/O interface allowing operation with 3.3-V or 5.0-V devices
• Programmable speed/power optimization with individual macrocell power-saving modes

Complex Programmable Logic Devices Applications

• Address decoding and bus interface logic
• State machine implementation and timing control
• Replacement for standard logic gates (PALs, GALs, 22V10s)
• Data acquisition and signal processing circuits

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix corresponds to the required speed grade (-10) and package type (PLCC-84). Confirm RoHS compliance status as specifications may vary by manufacturing batch. Ensure design tools support the MAX 7000S architecture for proper compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require ISP capability and boundary-scan testing within a CPLD architecture. The -10 speed grade provides a 6 ns delay suitable for moderate-speed applications. Consider the 128 macrocell capacity against logic density requirements; higher density options are available in the same family if more resources are needed.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 series, which utilizes second-generation MAX architecture. The 'S' designation indicates In-System Programmability, while 'L' typically denotes the PLCC package variant. The MAX 7000 family is designed to replace discrete logic components, offering reprogrammability and integration of SSI, MSI, and LSI functions.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other MAX 7000S devices such as EPM7128E or EPM7160S, though pin counts and resource densities differ. For legacy system upgrades, verify voltage compatibility and timing constraints before substituting with newer FPGA or CPLD families.
