EPM7128ATC100-7

EPM7128ATC100-7 Description

The EPM7128ATC100-7 is a high-performance Complex Programmable Logic Device (CPLD) from Altera's (now Intel) MAX® 7000A series. Designed for surface-mount applications, this device integrates 128 macrocells and 8 logic blocks, delivering 2,500 equivalent gates with a 7.5 ns maximum propagation delay. Operating within a 3V to 3.6V internal supply range, it is optimized for low-power, high-speed logic integration in industrial and commercial environments. The 100-pin TQFP package ensures compact PCB integration, while its EE PLD (Electrically Erasable PLD) architecture allows for in-system reprogrammability, making it ideal for prototyping and iterative design processes.

EPM7128ATC100-7 Features

• High-Speed Performance: 7.5 ns max delay ensures rapid signal processing for time-critical applications.
• 128 Macrocells: Provides ample logic capacity for complex state machines and glue logic.
• Low-Voltage Operation: 3V–3.6V supply reduces power consumption, suitable for battery-powered or energy-efficient designs.
• 84 I/O Pins: Offers extensive interfacing flexibility for peripheral connectivity.
• In-System Programmability (ISP): Supports field updates without physical removal, reducing downtime.
• Industrial Temperature Range: Operates reliably from 0°C to 70°C, making it suitable for commercial and light industrial use.
• MAX 7000A Architecture: Combines EEPROM-based configurability with high-density logic, outperforming older PLD families in speed and flexibility.

EPM7128ATC100-7 Applications

• Embedded Systems: Ideal for bus interfacing, address decoding, and control logic in microcontroller-based designs.
• Communications Equipment: Used in protocol bridging, signal conditioning, and data routing for telecom hardware.
• Industrial Automation: Implements PLC logic, motor control timing, and sensor interfacing due to its deterministic latency.
• Consumer Electronics: Enables display controllers, input multiplexing, and power management in smart devices.
• Prototyping & Education: Its reprogrammability makes it a preferred choice for FPGA/ASIC prototyping and academic projects.
