EPM7032STC44-7F

Complex Programmable Logic Devices Overview

The Altera EPM7032STC44-7F is a MAX 7000S series Complex Programmable Logic Device (CPLD) housed in a 44-pin Thin Quad Flat Pack (TQFP). It contains 32 macrocells organized into two logic array blocks, providing 600 usable gates and up to 36 user I/O pins. The device operates at 5.0 V with a maximum propagation delay of 5 ns and supports counter frequencies up to 175.4 MHz. As an in-system programmable (ISP) variant, it features built-in JTAG boundary-scan test circuitry and EEPROM storage for reprogrammability.

Complex Programmable Logic Devices Feature Summary

• In-system programmability via IEEE Std. 1149.1 JTAG interface
• High-performance 5 ns pin-to-pin delay with 175.4 MHz counter speed
• EEPROM-based non-volatile memory allowing 100+ reprogramming cycles
• Fast input registers with 2.5 ns setup time for MAX 7000S devices

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification Revision 2.2 compliant logic interfaces
• Replacement for PALs, GALs, and standard PLDs in digital systems
• In-circuit testing and boundary-scan verification
• Mixed-voltage system integration with 3.3-V or 5.0-V devices

Complex Programmable Logic Devices Procurement Notes

Verify the 'F' suffix indicates constant algorithm testing for compatibility with specific in-circuit testers that do not support adaptive algorithms. Confirm package integrity for the TQFP-44 form factor. Check RoHS compliance status as historical data may vary by manufacturing batch. Ensure programming hardware supports the 5.0 V ISP requirements.

Complex Programmable Logic Devices Selection Notes

Select this model when 32 macrocells are sufficient for the design logic density. Choose the -7 speed grade for 5 ns timing requirements. Opt for the 'S' variant if JTAG boundary-scan or in-system programming is required. Note that MultiVolt I/O operation is unavailable in 44-pin packages; verify voltage levels against connected components.

Complex Programmable Logic Devices Part Context

This component belongs to the MAX 7000 family, utilizing Altera’s second-generation MAX architecture. It is part of the MAX 7000S subset, which adds ISP capabilities and enhanced features like fast input registers compared to the base MAX 7000E series. The device is designed for high-density integration of SSI, MSI, and LSI logic functions.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes within the same family include EPM7032STC44-5, EPM7032STC44-6, and EPM7032STC44-10, differing only in speed grades. For higher density, consider EPM7064STC44 variants. Non-Altera equivalents require careful evaluation of pinout compatibility and logic architecture differences.
