EPM3064ATC44-10N: Intel's Obsolete CPLD - Features, Specifications & Legacy Applications

The EPM3064ATC44-10N is a discontinued Complex Programmable Logic Device (CPLD) from Intel (formerly Altera), designed for high-performance embedded systems. Despite its obsolete status, this IC remains relevant for engineers maintaining legacy hardware due to its robust architecture and proven reliability. This guide provides an in-depth technical analysis of the EPM3064ATC44-10N, including its key features, electrical characteristics, and industrial use cases.

EPM3064ATC44-10N Technical Specifications

• Manufacturer: Intel (formerly Altera)
• Device Type: 3.3V CPLD
• Logic Capacity: 64 macrocells, 1,250 gates
• Speed Grade: -10 (10ns maximum t_PD)
• Package: 44-pin TQFP (10 10mm)
• I/O Count: 34 user pins
• Voltage Range: 3.0V to 3.6V operation
• Temperature Range: Commercial (0 C to +70 C)
• Programmability: In-system programmable (ISP) via JTAG

Detailed Feature Breakdown

1. High-Speed Logic Implementation

The -10 speed grade delivers 10ns pin-to-pin delays, enabling clock frequencies up to 100MHz. Four logic array blocks (LABs) provide flexible routing for combinational and sequential logic designs.

2. Power-Efficient Architecture

Operating at 3.3V with advanced CMOS technology, the device consumes <50mA typical current, making it suitable for power-sensitive applications.

3. Enhanced I/O Capabilities

34 I/O pins support multiple standards:

• 3.3V LVTTL/LVCMOS
• 5V-tolerant inputs
• Programmable slew rate control

4. Reliable Non-Volatile Storage

EEPROM-based configuration retains programming indefinitely (20+ years data retention) without requiring external configuration memory.
