EPM7064AETC100-4

Complex Programmable Logic Devices Overview

The Altera EPM7064AETC100-4 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 64 macrocells organized into four Logic Array Blocks (LABs), providing approximately 1250 usable gates. The device operates with a supply voltage range of 3.0 V to 3.6 V and supports up to 68 I/O pins. It utilizes EEPROM technology for non-volatile configuration storage, allowing for system reprogrammability. The component is housed in a TQFP-100 surface-mount package and is rated for commercial temperature operation from 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells distributed across 4 Logic Array Blocks (LABs)
• EEPROM-based non-volatile memory for instant-on operation
• Supports 68 I/O pins with flexible logic function assignment
• System In-Programmability (SIPI) capability via JTAG

Complex Programmable Logic Devices Applications

• Protocol conversion and interface bridging in embedded systems
• Address decoding and bus arbitration in industrial control units
• State machine implementation for automated machinery
• Logic replacement for legacy discrete gate circuits

Complex Programmable Logic Devices Procurement Notes

Verify manufacturer authenticity as Altera was acquired by Intel, which is now Intel FPGA. Confirm the specific speed grade suffix (-4) matches design timing requirements. Check for RoHS compliance status relative to production date, as older batches may differ. Ensure EOL or lifecycle status is current before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the target logic density. The -4 speed grade indicates a maximum propagation delay suitable for moderate-speed applications. Compare against the EPM7064STC100 series if higher performance or extended temperature ranges are required. Ensure the TQFP-100 footprint aligns with existing PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000S CPLD family, an evolution of the original MAX 7000 series offering improved performance and lower power consumption. It serves as a mid-range solution between smaller PLDs and larger FPGAs, balancing cost and flexibility for general-purpose programmable logic needs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include the EPM7064STC100-4 for potentially different speed grades or packaging variants. Cross-family migration to MAX II or MAX V series requires schematic redesign due to architectural differences.
