AMD XC3064L-8TQ144C

Overview

XC3064L-8TQ144C from AMD is a field-programmable gate array (FPGA) in the XC3000L family, featuring 64 logic cells, 8 ns maximum propagation delay, and 144-pin TQFP packaging. It implements combinational and sequential logic for digital control systems in industrial PLCs and legacy communication interface adapters.

For engineers reviewing the XC3064L-8TQ144C datasheet, pinout, applications, or equivalent options, key selection criteria include logic cell count, speed grade (-8), package thermal profile, I/O voltage compatibility (5 V TTL), and configuration memory retention requirements.

Technical Context

The XC3064L-8TQ144C uses SRAM-based configuration with external PROM loading, supports IEEE 1149.1 JTAG boundary-scan testing, and operates over 0°C to 70°C commercial temperature range. Its architecture includes configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources routed via segmented metal lines.

It implements synchronous design methodologies with global clock routing, supports registered outputs per CLB, and requires external configuration PROM (e.g., XCF01S) for power-on initialization. No internal oscillator or PLL is integrated.

Manufacturer

AMD (Advanced Micro Devices) is a U.S.-based semiconductor company founded in 1969, specializing in high-performance computing, graphics, and adaptive SoC solutions.

The XC3000L family was designed for cost-sensitive, low-power digital logic replacement in commercial embedded systems where reprogrammability and 5 V interoperability were critical.

FAQ

What is the configuration method for XC3064L-8TQ144C?

The XC3064L-8TQ144C uses external serial configuration PROM (e.g., XCF01S) loaded at power-up. It has no internal nonvolatile memory, so configuration must be reloaded each time power is applied. JTAG port supports boundary-scan testing and in-system programming, but does not replace the need for external PROM in normal operation. XC3064L-8TQ144C relies on this external source for functional initialization.

Does XC3064L-8TQ144C support hot-swap or live insertion?

No, XC3064L-8TQ144C does not support hot-swap. Its I/O structure lacks bus-hold or hot-swap protection circuitry, and power sequencing requirements mandate VCC stabilization before applying signals. Applying I/O voltages before VCC may cause latch-up or damage. XC3064L-8TQ144C must be powered in strict sequence: VCC first, then I/O, then clocks and signals.

What is the maximum operating frequency of XC3064L-8TQ144C?

The XC3064L-8TQ144C is rated for a maximum system clock frequency of 125 MHz, derived from its 8 ns maximum propagation delay specification. This assumes ideal routing, minimal fanout, and proper termination. Real-world performance depends on design implementation, including CLB utilization, interconnect delay, and I/O loading. XC3064L-8TQ144C timing is guaranteed only under conditions specified in the original AMD data sheet.

Can XC3064L-8TQ144C operate at 3.3 V?

No, XC3064L-8TQ144C is strictly a 5 V device. Its internal SRAM cells, I/O buffers, and voltage reference circuits are designed for 5 V ±5% operation. Applying 3.3 V to VCC will result in configuration failure, metastable logic states, or permanent damage. XC3064L-8TQ144C requires a regulated 5 V supply meeting AMD's recommended ripple and transient specifications.

Is JTAG debugging supported on XC3064L-8TQ144C?

XC3064L-8TQ144C supports IEEE 1149.1 JTAG boundary-scan for interconnect testing and device identification, but does not provide in-circuit debug capability such as breakpoint setting or register visibility. JTAG access is limited to TAP controller operations and BSDL-defined instructions. XC3064L-8TQ144C does not implement embedded debug modules or processor-like debug features.
