EPM7032LI44-15

Complex Programmable Logic Devices Overview

The Altera EPM7032LI44-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 32 macrocells, 600 usable gates, and 36 I/O pins housed in a 44-pin PLCC package. The device operates at a supply voltage of 4.5V to 5.5V with a maximum propagation delay of 15 ns. It utilizes EEPROM technology for non-volatile storage and supports standard surface-mount installation.

Complex Programmable Logic Devices Feature Summary

• 32 Macrocells and 600 usable gates within 2 Logic Array Blocks
• 36 User I/O Pins in a 44-pin PLCC package
• 15 ns Maximum Propagation Delay
• EEPROM-based programmable logic architecture

Complex Programmable Logic Devices Applications

• General-purpose digital logic implementation
• Replacement for legacy PAL/GAL devices
• Interface bridging between different logic families

Complex Programmable Logic Devices Procurement Notes

This component is marked as obsolete and no longer manufactured by Altera. Verification of authenticity is critical when sourcing from secondary markets due to the end-of-life status. Buyers should confirm the specific speed grade (-15) and package type (PLCC-44) match design requirements before acquisition.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 32 macrocells and 5V operation. The -15 speed grade indicates a 15 ns delay, which is slower than the -5 or -6 grades available in the same family. Ensure the PCB footprint matches the 44-PLCC (16.59x16.59 mm) dimensions and that the system power supply provides 4.5V to 5.5V.

Complex Programmable Logic Devices Part Context

The EPM7032LI44-15 is part of the original MAX 7000 series, distinct from the later MAX 7000S (ISP-capable) or MAX 7000A/B (low-voltage) variants. It represents the second-generation MAX architecture using CMOS EEPROM cells. This specific suffix 'L' typically denotes the plastic J-lead chip carrier package variant within the broader EPM7032 product line.

Complex Programmable Logic Devices Replacement Considerations

Public documentation lists the ATF1502AS-10JU44 from Microchip Technology as a similar replacement option.
