EPM7064BFC100-5 CPLD - High-Performance In-System Programmable Logic Device | Altera
The EPM7064BFC100-5 by Altera is a cutting-edge Complex Programmable Logic Device (CPLD) designed for high-performance digital systems. With its in-system programmability (ISP), this device allows engineers to reconfigure logic on-the-fly, streamlining prototyping and reducing time-to-market. The CPLD operates at a blistering 5ns maximum propagation delay, ensuring real-time responsiveness for critical applications like motor control and data acquisition. Its 2.375V 2.625V internal voltage range minimizes power consumption, making it ideal for battery-operated devices. The 100-LBGA package (11x11mm) offers a compact footprint for space-constrained designs, while the 68 I/O pins enable extensive peripheral connectivity.
Architecturally, the EPM7064BFC100-5 boasts 4 logic blocks and 64 macrocells, equivalent to 1,250 gates, providing ample resources for state machines, glue logic, and interface bridging. The device supports JTAG boundary-scan testing, simplifying PCB validation. With an operating temperature range of 0 C to 70 C, it performs reliably in commercial and industrial environments. Altera's MAX+PLUS II development software (or Quartus II for newer versions) offers seamless design integration with VHDL/Verilog support, enabling rapid implementation of complex logic functions.
Key technical specifications include 5V tolerant I/Os for mixed-voltage system compatibility and 10,000 program/erase cycles for robust field updates. The FineLine BGA package enhances thermal performance with a 4-layer PCB recommendation for optimal signal integrity. Security features include programmable encryption to protect intellectual property. Clock networks support global and local routing, with dedicated inputs for low-skew distribution.
The EPM7064BFC100-5 excels in embedded control applications across industries. In automotive systems, it manages CAN bus interfaces and dashboard logic. For telecom infrastructure, it handles protocol conversion in base stations. Industrial designers leverage its deterministic timing for PLC ladder logic and safety interlocks. Consumer electronics benefit from its ability to consolidate legacy ICs into a single programmable solution, reducing BOM costs. Its live-insertion capability makes it suitable for hot-swappable modules in server backplanes.
Compared to FPGAs, this CPLD offers instant-on operation without configuration memory, critical for power-up sequencing. The non-volatile EEPROM technology retains programming during outages. For legacy support, it maintains pin compatibility with earlier MAX 7000S devices. When sourcing, verify lead-free (RoHS) compliance for modern manufacturing. For high-reliability applications, consider the EPM7064BFC100-5N industrial-grade variant (-40 C to +85 C). Always reference Altera's AN 265: Power Sequencing Guidelines for robust power-up behavior.
