EPM7064BTC44-5: Altera's High-Performance CPLD for Embedded Systems | Fast 5ns Delay
The EPM7064BTC44-5 is a cutting-edge Complex Programmable Logic Device (CPLD) from Altera (now Intel), engineered to deliver exceptional performance for demanding digital applications. With its 5ns maximum propagation delay and 64 macrocells, this device excels in high-speed logic implementations. Its 2.375V to 2.625V operating voltage range ensures stable performance across varying power conditions, while the 44-TQFP package (10x10mm) offers compact and efficient PCB integration. Designed for in-system programmability (ISP), the EPM7064BTC44-5 simplifies firmware updates without physical removal, making it a versatile choice for iterative development cycles.
This CPLD features 4 logic blocks and 36 I/O pins, providing ample resources for complex logic designs and peripheral interfacing. The device's 1250 equivalent gates enable sophisticated digital circuit implementations, from state machines to data path control. Operating within a 0 C to 70 C temperature range, it ensures reliability in diverse environments. The surface-mount design (44-TQFP) enhances thermal performance and manufacturing efficiency, while the electrically erasable (EE) technology allows for repeated reprogramming, extending product lifecycles.
The EPM7064BTC44-5 shines in real-time systems where speed and reliability are paramount. Its architecture supports parallel processing, making it ideal for DSP acceleration, communication protocol bridging, and industrial automation. The 36 I/O pins accommodate bidirectional data flow, clock distribution, and interfacing with memory or sensors. Engineers appreciate its predictable timing characteristics, enabled by Altera's proven MAX 7000S architecture. With 5V-tolerant I/Os, it seamlessly integrates with legacy systems while maintaining low-power operation (typical ICC under 10mA at 2.5V).
Applications span from consumer electronics (smart home controllers, wearable tech) to mission-critical systems (medical devices, aerospace subsystems). In telecommunications, it handles glue logic for FPGA companion chips, while automotive designs leverage its robustness for sensor fusion and ECU interfaces. The device's ISP capability via JTAG simplifies field upgrades, a critical feature for IoT edge devices. Compared to FPGAs, this CPLD offers deterministic latency and instant-on operation advantages for power-up sequencing and control plane management.
Altera's Quartus II software provides comprehensive development support, from schematic entry to timing analysis. The EPM7064BTC44-5 remains a cost-effective alternative to ASICs for medium-complexity designs, with 10,000 program/erase cycles endurance. Its non-volatile configuration memory eliminates external boot devices, reducing BOM costs. For engineers seeking a balance between flexibility and performance, this CPLD delivers a compelling solution whether prototyping or scaling to production. With over two decades of field proven reliability in the MAX 7000 family, it continues to power innovation across industries.
