EPM7064BTC100-7: Altera's High-Performance CPLD - Features, Applications & Datasheet
The EPM7064BTC100-7 from Altera (now Intel) is a high-performance Complex Programmable Logic Device (CPLD) designed for advanced digital systems. With 64 macrocells and 1,250 gates, it delivers robust logic integration in a compact 100-TQFP package (14x14mm). Its electrically erasable (EE) PLD architecture allows for repeated reprogramming, making it ideal for prototyping and production. Operating at a 2.375V 2.625V internal supply voltage and featuring a 7.5ns maximum propagation delay, this CPLD ensures rapid signal processing for time-sensitive applications. The device supports 68 I/O pins, enabling versatile interfacing with peripherals, and operates reliably in temperatures ranging from 0 C to 70 C.
Engineers favor the EPM7064BTC100-7 for its 4 logic blocks and surface-mount (SMT) compatibility, which streamline PCB design. Its 7.5ns tpd ensures minimal latency, critical for real-time systems like automotive control modules or industrial automation. The 100-TQFP package balances space efficiency with thermal performance, while the EE PLD technology simplifies firmware updates. Altera's ongoing Active status guarantees long-term availability and support, reducing obsolescence risks for OEMs.
Key technical specifications include a 64-macrocell count, organized into 4 logic blocks, providing ample resources for state machines, counters, and combinatorial logic. The device s 1250-gate equivalent capacity supports moderate complexity designs, while its 68 I/Os accommodate diverse bidirectional communication needs. Power efficiency is achieved through a 2.5V nominal supply, reducing energy consumption in battery-operated systems. The 7.5ns delay outperforms many legacy CPLDs, making it suitable for high-speed interfaces like UART, SPI, or custom bus protocols.
The EPM7064BTC100-7 excels in telecommunications (protocol bridging), consumer electronics (display controllers), automotive (sensor interfacing), and industrial automation (PLC logic). Its reprogrammability allows for field upgrades, while the robust TQFP package resists mechanical stress. Designers leverage its low-latency performance for motor control or real-time data processing. With Altera s Quartus II toolchain, development is streamlined from simulation to deployment.
For engineers seeking a reliable, mid-density CPLD, the EPM7064BTC100-7 offers an optimal blend of speed, flexibility, and I/O options. Its industry-standard packaging and extended temperature range ensure compatibility with harsh environments. Available through authorized distributors, this CPLD remains a cost-effective solution for replacing ASICs or discrete logic.
