EPM3032ATC44-10NAA

Complex Programmable Logic Devices Overview

The Altera EPM3032ATC44-10NAA is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 600 usable gates, 32 macrocells organized into two logic array blocks (LABs), and supports up to 34 user I/O pins in a 44-pin TQFP package. The device operates on a 3.3 V supply with a maximum propagation delay of 4.5 ns and counter frequencies reaching 227.3 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration, allowing reprogramming up to 100 times.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture supporting In-System Programming (ISP) via IEEE Std. 1149.1 JTAG interface
• MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic levels
• Programmable interconnect array (PIA) providing predictable timing performance
• Supports hot-socketing and includes boundary-scan test (BST) circuitry

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification compliant logic interfacing
• TTL emulation for legacy system integration
• High-density small-scale (SSI), medium-scale (MSI), and large-scale (LSI) logic functions

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'AA' against official documentation, as standard datasheets typically list grades such as -4, -5, -7, or -10 without this suffix. Confirm current availability status, as MAX 3000A devices are generally considered obsolete or end-of-life products requiring careful lifecycle management.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require low-cost, high-performance CPLDs with fast pin-to-pin delays of 4.5 ns. Ensure the application benefits from the MultiVolt I/O capability for mixed-voltage systems. Consider the 32 macrocell capacity and 34 I/O limit for complex logic replacement tasks involving PALs, GALs, or pLSI devices.

Complex Programmable Logic Devices Part Context

The EPM3032ATC44-10NAA is part of the MAX 3000A family, which ranges from 600 to 10,000 usable gates. This specific model represents the entry-level density within the series, offering 32 macrocells and 2 LABs. It shares architectural features with higher-density variants like the EPM3064A and EPM3128A but provides fewer resources and I/O pins.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may be limited due to the obsolete status of the MAX 3000A family. Verify compatibility with successor families such as MAX II or MAX V, noting differences in voltage levels, programming interfaces, and feature sets.
