EPM7064STC44-5F

Complex Programmable Logic Devices Overview

The Altera EPM7064STC44-5F is a MAX 7000S series Complex Programmable Logic Device (CPLD) housed in a 44-pin Thin Quad Flat Pack (TQFP). It features 64 macrocells, 1,250 usable gates, and 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. It utilizes EEPROM technology for non-volatile storage and includes an 'F' suffix indicating testing via the constant algorithm for In-System Programming (ISP).

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface.
• EEPROM-based architecture allowing reprogramming up to 100 times.
• Configurable expander product terms providing up to 32 product terms per macrocell.
• Programmable power-saving mode reducing macrocell power dissipation by over 50%.

Complex Programmable Logic Devices Applications

• PCI-compliant logic interfacing.
• Replacement for PALs, GALs, and pLSI devices.
• High-density integration of SSI, MSI, and LSI logic functions.

Complex Programmable Logic Devices Procurement Notes

Verify the 'F' suffix indicates constant algorithm testing for ISP compatibility with specific in-circuit testers. Confirm package integrity for the TQFP-44 form factor. Check RoHS compliance status as this component may be obsolete or lead-containing based on family history.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 5.0 V operation and 36 I/Os in a compact 44-pin package. Note that MultiVolt I/O is not available in 44-pin packages; voltage levels are fixed to 5.0 V for I/O interfaces.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000S family, which adds ISP capabilities to the enhanced MAX 7000E architecture. The EPM7064 represents the mid-range density option within the 44-pin variant lineup, offering 64 macrocells compared to the 32 in the EPM7032S.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other speed grades of the EPM7064S series (e.g., -6, -7, -10) provided timing requirements allow. Verify software toolchain support for older MAX 7000 devices if migrating from legacy systems.

Complex Programmable Logic Devices FAQ

What does the 'F' suffix indicate?

The 'F' suffix denotes that the device was tested using a constant algorithm for In-System Programming, ensuring compatibility with test equipment that cannot support adaptive algorithms.

Is MultiVolt I/O supported?

No, MultiVolt I/O interface operation is not available in 44-pin packages. These devices operate strictly at 5.0 V for I/O.

How many product terms are available per macrocell?

Each macrocell provides five primary product terms, supplemented by shareable and parallel expanders to achieve up to 32 total product terms.
