EPM3128ATI100-10N

Complex Programmable Logic Devices Overview

The Altera EPM3128ATI100-10N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 128 macrocells, 2,500 usable gates, and 98 maximum user I/O pins in a 100-pin TQFP package. The device operates at a 3.3 V supply voltage with a typical pin-to-pin propagation delay of 5.0 ns and a maximum counter frequency of 192.3 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration, supporting up to 100 reprogramming cycles.

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface with advanced pin-locking
• MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic levels
• Programmable interconnect array (PIA) providing predictable routing delays
• Built-in boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification Revision 2.2 compatible designs
• Mixed-voltage system integration requiring 5V/3.3V/2.5V tolerance
• Industrial temperature range applications
• High-density SSI, MSI, and LSI logic functions

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'I' against official documentation to confirm industrial temperature range classification. Confirm package type matches the 100-pin TQFP specification. Check current availability status as older MAX 3000A devices may have limited stock or end-of-life status from distributors.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 2,500 gates are sufficient for the design. The -10 speed grade offers 5.0 ns delay suitable for frequencies up to 192.3 MHz. Ensure the design requires 3.3 V core voltage with mixed-voltage I/O capabilities. Consider alternative MAX 3000A models if higher gate counts or different package options are needed.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A family, which includes devices ranging from 600 to 10,000 usable gates. The EPM3128A variant sits between the EPM3064A and EPM3256A in terms of logic density. The family is characterized by its EEPROM-based architecture and support for both parallel and shareable expander product terms within Logic Array Blocks (LABs).

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other EPM3128A variants with different speed grades (-4, -5, -6, -7) or packages. Cross-family migration to MAX II or MAX V series requires architectural redesign due to differences in logic structure and programming technology.
