EPM7128AFC100-6 - Altera High-Speed CPLD with 128 Macrocells & 5ns Delay | 3V EE PLD
The EPM7128AFC100-6 by Altera (now Intel) is a high-performance Complex Programmable Logic Device (CPLD) designed for demanding embedded applications. With 128 macrocells, 5ns maximum propagation delay (tpd), and 3V to 3.6V operation, this device delivers exceptional speed and energy efficiency. Its 100-FBGA (11x11) package ensures compact integration, while the EE (Electrically Erasable) PLD technology allows for flexible in-system reprogramming. Ideal for real-time control, data communication, and industrial automation, this CPLD combines Altera's reliability with cutting-edge logic density.
Technical Specifications: The EPM7128AFC100-6 features 8 logic blocks and 84 I/O pins, providing ample resources for complex state machines, counters, and glue logic. Its 2500-gate equivalent capacity supports intricate designs without external components. Operating in a commercial temperature range (0 C to 70 C), this device ensures stability in diverse environments. The FBGA packaging is optimized for surface-mount assembly, making it suitable for space-constrained PCBs in modern electronics.
Performance Advantages: With a 5ns max delay time, the EPM7128AFC100-6 outperforms many CPLDs in its class, enabling rapid signal processing for high-speed interfaces like SPI, I2C, and UART. The low-voltage operation (3V) reduces power consumption, extending battery life in portable devices. Its electrically erasable architecture allows engineers to iterate designs quickly, reducing development cycles. Altera's proven MAX 7000AE series foundation ensures long-term availability and compatibility with industry-standard tools like Quartus II.
Applications: This CPLD is widely used in industrial automation (PLC control, motor drives), telecom infrastructure (signal routing, protocol bridging), and medical devices (patient monitoring, diagnostic equipment). Automotive systems leverage its reliability for ECU control logic, while consumer electronics benefit from its glue logic integration in smart home devices. The 84 I/O pins enable versatile interfacing with sensors, displays, and memory modules, making it a cornerstone of embedded system design.
Procurement & Support: As an active Altera/Intel product, the EPM7128AFC100-6 is available through authorized distributors with full traceability. Design resources include HDL code examples, timing analysis tools, and reference designs to accelerate implementation. For high-volume orders, Intel offers supply chain assurances and extended lifecycle support, ensuring continuity for critical applications. Engineers can access Altera's MAX+PLUS II or Quartus Prime software for seamless development with this CPLD family.
