EPM7032BUC49-7 - Altera Obsolete CPLD | Specifications & Applications
The EPM7032BUC49-7 is a Complex Programmable Logic Device (CPLD) from Altera's MAX 7000B family, designed for high-performance, low-cost digital logic solutions. Despite being marked as obsolete, this CPLD remains a preferred choice for engineers working on legacy systems or projects requiring stable, time-tested components. With 32 macrocells, 600 equivalent gates, and an ultra-low propagation delay of 7.5ns, it delivers efficient logic integration for applications like glue logic replacement, address decoding, and state machine implementation. Its in-system programmability (ISP) allows for flexible updates without hardware rework, making it a versatile option for prototyping and production.
This CPLD operates on a tight internal voltage range of 2.375V to 2.625V, ensuring low power consumption while maintaining reliability. Packaged in a compact 49-LFBGA (7x7mm) format, it suits space-constrained designs without sacrificing performance. The 36 I/O pins provide ample connectivity, enabling seamless integration with peripherals and other ICs. With a commercial temperature range of 0 C to 70 C, the EPM7032BUC49-7 is robust enough for industrial control systems, medical devices, and aerospace applications where component longevity is critical.
Altera's MAX 7000B series, including the EPM7032BUC49-7, is renowned for its high-speed logic processing and design flexibility. The device features two logic blocks, each configurable for combinational or sequential operations, supporting complex digital circuits. Its surface-mount (SMT) design enhances PCB space efficiency, while the lead-free BGA package ensures compliance with modern environmental standards. Though newer CPLDs and FPGAs have since surpassed it in density, this model remains relevant for cost-sensitive or backward-compatible projects.
Applications of the EPM7032BUC49-7 span industrial automation, telecommunications, and consumer electronics. It excels in replacing discrete logic gates, reducing board clutter, and simplifying circuit debugging. Engineers also leverage it for custom peripheral interfaces and real-time control systems due to its deterministic timing and reprogrammability. For hobbyists, it offers an accessible entry point into programmable logic without the complexity of modern FPGA toolchains.
In summary, the EPM7032BUC49-7 balances performance, power efficiency, and compactness, making it a pragmatic choice for niche applications. While newer alternatives exist, its proven track record and ease of use ensure continued demand.
