EPM3128ATC100-10

Complex Programmable Logic Devices Overview

The Altera EPM3128ATC100-10 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 128 macrocells, 8 logic array blocks (LABs), and 2,500 usable gates. The device provides up to 98 user I/O pins in a 100-pin TQFP package. Electrical specifications include a maximum propagation delay of 5 ns, a maximum counter frequency of 192.3 MHz, and operation at a 3.3 V supply voltage. It utilizes CMOS EEPROM technology for non-volatile configuration.

Complex Programmable Logic Devices Feature Summary

• Supports 3.3-V In-System Programming (ISP) via IEEE Std. 1149.1 JTAG interface with advanced pin-locking.
• Features MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic levels.
• Includes built-in boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990.
• Utilizes a Programmable Interconnect Array (PIA) for predictable performance.

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification Revision 2.2 compatible designs.
• Mixed-voltage system integration requiring 2.5 V, 3.3 V, or 5.0 V I/O compatibility.
• High-density small-scale, medium-scale, and large-scale integration logic functions.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence. Confirm that the specific ordering suffix matches the required speed grade and package type. Ensure programming hardware supports the IEEE Std. 1532 ISP standard for in-system configuration.

Complex Programmable Logic Devices Selection Notes

Select the EPM3128ATC100-10 when 128 macrocells and 2,500 usable gates are sufficient for the design. The -10 speed grade indicates a 5 ns maximum propagation delay. Verify that the 100-pin TQFP package fits the PCB layout constraints and that the 3.3 V core voltage aligns with the system power architecture.

Complex Programmable Logic Devices Part Context

This device is part of the Altera MAX 3000A family, which offers low-cost, high-performance CPLDs. The family ranges from 600 to 10,000 usable gates. The EPM3128A variant specifically bridges the gap between lower-density devices like the EPM3064A and higher-density options like the EPM3256A.

Complex Programmable Logic Devices Replacement Considerations

Compatible alternatives within the same family include EPM3128ATC100-7 and EPM3128ATC100-5, which offer faster speed grades. For pin-compatible upgrades, consider EPM3256A variants if additional macrocells are required, though package and pin counts may differ.
