EPM7032VTC44-15

Complex Programmable Logic Devices Overview

The Altera EPM7032VTC44-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 32 macrocells and supports up to 36 I/O lines within a 44-pin Thin Quad Flat Package (TQFP). The device utilizes EEPROM technology for non-volatile configuration, allowing for in-system programmability via the IEEE 1149.1 JTAG interface. Key electrical parameters include a maximum propagation delay of 15 ns and a maximum operating frequency of approximately 76.9 MHz. It operates on a single 5.0 V supply voltage with an industrial temperature range capability.

Complex Programmable Logic Devices Feature Summary

• 32 Macrocells organized into 2 Logic Array Blocks (LABs)

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to the age of the MAX 7000 series. Confirm package integrity and pin alignment before soldering. Check for lead-free status if RoHS compliance is required for the specific manufacturing environment. Ensure design tools support legacy device families.

Complex Programmable Logic Devices Selection Notes

Select this model when 32 macrocells are sufficient for the logic density requirements. Compare against the EPM7032STC44 variant if higher speed or different packaging is needed. Verify that the 5.0 V I/O levels match the system voltage domains. Consider the TQFP-44 footprint constraints during PCB layout.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000S CPLD family, which introduced ISP capabilities to the established MAX 7000 line. It serves as a bridge between simple PLDs and larger FPGAs, offering a cost-effective solution for moderate logic complexity. The 'V' suffix typically denotes the specific speed grade and package variation within the standard product lineup.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to discontinuation. Evaluate Microchip ATF15xx series devices for functional equivalence. Verify logic capacity and I/O compatibility when selecting third-party alternatives.
