AMD XC3064A-7PC84C

Overview

XC3064A-7PC84C from AMD is a field-programmable gate array (FPGA) with 64 configurable logic blocks, 1,536 usable gates, and 84-pin plastic leaded chip carrier (PLCC) packaging. It operates at a maximum system clock frequency of 7 ns propagation delay and supports in-system reprogramming via external configuration PROMs. It is used in digital logic prototyping and glue-logic replacement for industrial control interfaces.

For engineers reviewing the XC3064A-7PC84C datasheet, pinout, applications, or equivalent options, key selection considerations include logic density, PLCC-84 thermal and mechanical compatibility, 7 ns speed grade, I/O count (68 user I/Os), and configuration mode support (master serial, slave serial, boundary-scan).

Technical Context

The XC3064A-7PC84C implements a fine-grain, SRAM-based architecture with configurable logic blocks (CLBs), input/output blocks (IOBs), and programmable interconnect matrix (PIM). Each CLB contains two 3-input lookup tables (LUTs), flip-flops, and carry logic for arithmetic functions.

Configuration is performed via serial bitstream loading using JTAG boundary-scan (IEEE 1149.1 compliant) or parallel mode. The device requires external VCC = 5.0 V ± 5% and supports TTL-compatible I/O levels with programmable output slew rate control.

FAQ

What is the maximum operating frequency supported by XC3064A-7PC84C?

The XC3064A-7PC84C supports a maximum system clock frequency of 143 MHz, derived from its 7 ns propagation delay specification. This timing applies to internal CLB-to-CLB paths under worst-case voltage and temperature conditions. Actual achievable frequency depends on design routing, fan-out, and I/O loading, but the 7 ns grade ensures timing closure for synchronous logic running below 143 MHz.

Does XC3064A-7PC84C support in-system programming?

Yes, XC3064A-7PC84C supports in-system programming via its JTAG boundary-scan interface (TCK/TMS/TDI/TDO pins) and serial configuration modes. It does not require external programming hardware beyond a standard JTAG adapter. Configuration bitstream can be loaded dynamically during operation if the design implements appropriate control logic and memory management.

What power supply requirements does XC3064A-7PC84C have?

XC3064A-7PC84C requires a single 5.0 V ± 5% supply (VCC) delivered to four dedicated pins. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum per VCC pin) are mandatory near each supply pin. No auxiliary voltages (e.g., VCCO, VREF) are required, as I/O levels are fixed TTL-compatible.

How many user I/O pins does XC3064A-7PC84C provide?

XC3064A-7PC84C provides 68 user-programmable I/O pins out of its 84-pin PLCC package. The remaining 16 pins are assigned to power (VCC), ground (GND), configuration (PROGRAM, INIT), and JTAG (TCK/TMS/TDI/TDO) functions. All 68 I/Os support programmable direction, drive strength, and slew rate control.

Is XC3064A-7PC84C compatible with Xilinx XC3000A family development tools?

Yes, XC3064A-7PC84C is fully compatible with Xilinx Foundation Series and M1 software tools used for the XC3000A family. AMD licensed the architecture and toolchain from Xilinx, so bitstream generation, place-and-route, and simulation workflows remain identical. Pinout and timing models are interchangeable between AMD and Xilinx variants of the same speed/package grade.
