Overview
The EPM7064AETC44- is a member of Intel's (formerly Altera) MAX 7000 family of CPLDs. It provides 64 macrocells and operates at 5V, packaged in a 44-pin Thin Quad Flat Pack (TQFP). This device is designed for high-performance logic integration, offering in-system programmability for flexible design iterations. As a non-volatile CPLD, it retains its configuration when powered off, making it suitable for systems requiring instant-on operation. The EPM7064 series is widely used across industries due to its reliability and mature technology, though newer low-voltage alternatives exist for power-sensitive applications.
Structure and Working Principle
The device architecture consists of multiple Logic Array Blocks (LABs), each containing 16 macrocells. These connect through a Programmable Interconnect Array (PIA), allowing flexible routing between logic elements. Each macrocell can be configured for combinatorial or registered logic operations. The CPLD is programmed using Hardware Description Languages (HDL) or schematic entry, with configuration data stored in EEPROM cells. This technology enables thousands of reprogramming cycles, supporting design prototyping and field updates. The 44-pin TQFP package offers a compact footprint while maintaining good thermal characteristics for industrial environments.
Key Features
With 64 macrocells, the EPM7064AETC44- provides equivalent logic capacity to approximately 1,200-2,400 gates. It operates at 5V with typical propagation delays of 5-10ns, suitable for many control applications. The device supports 36 user I/O pins in the 44-pin package. Notable features include programmable slew rate control for EMI reduction, programmable power-saving modes, and security bits to prevent configuration copying. The in-system programmability (ISP) allows programming via a 4-pin JTAG interface, eliminating the need for physical device removal during development cycles.
Application Areas
This CPLD is commonly deployed in industrial control systems for logic glue, state machines, and interface bridging. Telecommunications equipment uses it for protocol conversion and signal conditioning. Embedded systems benefit from its instant-on capability for boot management and peripheral control. Other applications include automotive electronics (non-safety-critical), test equipment, and legacy system maintenance. While newer FPGAs offer greater density, the EPM7064 remains popular for simpler designs requiring deterministic timing and lower static power consumption compared to SRAM-based alternatives.
Maintenance and Precautions
Proper handling requires ESD precautions - use grounded workstations and wrist straps. During soldering, follow TQFP package guidelines with maximum temperature of 260°C for 10 seconds. Avoid exceeding absolute maximum ratings (7V input voltage, 125°C junction temperature). For long-term reliability, operate within recommended conditions (4.75-5.25V supply, 0-70°C commercial or -40-85°C industrial temperature ranges). Configuration data integrity can be verified through checksum validation. When designing, allocate sufficient I/O margin as 36 pins may limit complex interfaces.
B2B Procurement Guide
When sourcing the EPM7064AETC44-, verify authenticity through authorized distributors like Arrow, Avnet, or Future Electronics. Be cautious of counterfeit parts in the secondary market - request original packaging and lot traceability. Lead times vary; newer MAX V or MAX 10 devices may offer better availability. Consider minimum order quantities (MOQs) - full reels typically contain 250 or 500 units. Pricing fluctuates based on market conditions; negotiate volume discounts for orders exceeding 1,000 pieces. For prototyping, development kits like the MAX 7000 Breakout Board can accelerate design verification before production commits.
