EPM3064ATC44-10N

Complex Programmable Logic Devices Overview

The Altera EPM3064ATC44-10N is a CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family. It features 64 macrocells, 1,250 usable gates, and 66 maximum user I/O pins in a 44-pin TQFP package. The device operates at a 3.3-V supply voltage with a pin-to-pin logic delay of 10 ns and a setup time of 2.8 ns. It supports in-system programmability via IEEE Std. 1149.1 JTAG and includes MultiVolt I/O compatibility for 2.5-V, 3.3-V, and 5.0-V logic levels.

Complex Programmable Logic Devices Feature Summary

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

Complex Programmable Logic Devices Applications

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

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-10) against the datasheet Table 2 to confirm it corresponds to the 10 ns tPD specification. Ensure the package type matches the 44-pin TQFP form factor listed in Table 3. Confirm that the manufacturing source provides the correct IDCODE value for the EPM3064A device as defined in Table 9.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require 64 macrocells and 1,250 usable gates within a 44-pin footprint. The -10 speed grade is suitable for applications requiring 10 ns propagation delays. Consider the MAX 3000A architecture's ability to handle mixed-voltage I/O if interfacing with 5.0-V or 2.5-V systems while maintaining a 3.3-V core.

Complex Programmable Logic Devices Part Context

This device belongs to the MAX 3000A family, which offers high-performance, low-cost CPLDs. The family ranges from 600 to 10,000 usable gates across five device variants: EPM3032A, EPM3064A, EPM3128A, EPM3256A, and EPM3512A. The EPM3064A sits in the middle of this range, providing a balance of density and pin count for general-purpose logic applications.
