EPM3064ATC44-10

Complex Programmable Logic Devices Overview

The Altera EPM3064ATC44-10 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 64 macrocells, 1,250 usable gates, and 34 user I/O pins within a 44-pin Thin Quad Flat Pack (TQFP) package. The device operates on a 3.3 V supply with a maximum frequency of 222.2 MHz and a pin-to-pin propagation delay of 4.5 ns. It utilizes CMOS EEPROM technology for non-volatile configuration, supporting in-system programming via JTAG.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture allowing up to 100 reprogramming cycles
• In-system programmability (ISP) through IEEE Std. 1149.1 JTAG interface
• MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic levels
• Programmable interconnect array (PIA) providing predictable timing performance

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification compliant logic functions
• Transistor-to-transistor logic (TTL) emulation
• Small-scale to large-scale integration logic replacement

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number is listed as End-of-Life (EOL). Confirm RoHS compliance status, as datasheet references indicate potential non-compliant variants. Ensure sourcing from authorized distributors or verified secondary markets due to discontinuation.

Complex Programmable Logic Devices Selection Notes

Select the -10 speed grade for 4.5 ns delay requirements. Compare against EPM3032A for lower gate counts or EPM3128A for higher density. Verify package availability, as TQFP-44 is distinct from PLCC-44 or PQFP options within the same logic family.

Complex Programmable Logic Devices Part Context

Part of the MAX 3000A series, designed for low-cost, high-performance applications. It integrates with Altera development systems like Quartus Prime and supports VHDL/Verilog design entry. The architecture replaces legacy PALs, GALs, and pLSI devices.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents are unavailable due to EOL status. Consider EPM3064ALC44-7 (PLCC package) or EPM3064ATC100-10N (100-pin TQFP) for pin-compatible or footprint-adaptable alternatives within the same family.
