EPM3256ATI144-10 Description

The EPM3256ATI144-10 is a high-performance Complex Programmable Logic Device (CPLD) from Intel's MAX® 3000A series, designed for applications requiring flexible logic integration and rapid signal processing. This 256-macrocell device operates at a 3V to 3.6V internal supply voltage, delivering a maximum propagation delay (tpd) of 10 ns, making it suitable for high-speed logic implementations. Packaged in a 144-pin TQFP (Thin Quad Flat Package), it features 116 I/O pins, enabling extensive interfacing capabilities. Although marked as obsolete, its robust architecture—16 logic blocks and 5,000 equivalent gates—remains relevant for legacy designs requiring reliable, in-system programmable (ISP) logic solutions.

EPM3256ATI144-10 Features

• High-Speed Performance: 10 ns max delay ensures efficient timing-critical applications.
• Dense Logic Integration: 256 macrocells and 5,000 gates provide ample resources for complex logic designs.
• Flexible I/O Configuration: 116 programmable I/Os support versatile interfacing with peripherals.
• In-System Programmability (ISP): Allows field updates without physical removal, reducing downtime.
• Low-Power Operation: 3.3V core voltage aligns with modern low-power design requirements.
• Industrial Reliability: REACH unaffected and MSL 3 (168 hours) rated for robust handling.

EPM3256ATI144-10 Applications

• Legacy System Upgrades: Ideal for retrofitting older systems with programmable logic.
• Communication Interfaces: Used in UART, SPI, and I2C protocol bridging.
• Industrial Control Systems: Suitable for PLCs, motor control, and sensor interfacing.
• Embedded Systems: Acts as a glue logic for FPGA co-processing or I/O expansion.
• Test and Measurement Equipment: Provides reconfigurable logic for signal conditioning and timing control.

Conclusion of EPM3256ATI144-10

The EPM3256ATI144-10 stands out for its high-speed logic density and ISP flexibility, making it a pragmatic choice for legacy or cost-sensitive designs. While obsolete, its 5,000-gate capacity and 116 I/Os offer a balance of performance and versatility, particularly in industrial and embedded applications. Engineers seeking a proven, low-risk CPLD solution for timing-critical tasks may still find value in this Intel MAX® 3000A series device.
