AMD XC4003E-4PC84C

Overview

XC4003E-4PC84C from Xilinx is a Field-Programmable Gate Array (FPGA) with 3,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -4 speed grade (15 ns CLB propagation delay), and commercial temperature range (0°C to 70°C). It implements synchronous digital logic in embedded control and interface bridging applications.

For engineers reviewing the XC4003E-4PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (69 user I/Os), speed grade timing, PLCC-84 mechanical compatibility, and legacy 5 V CMOS interface support.

Technical Context

The XC4003E-4PC84C belongs to Xilinx's XC4000E FPGA family, built on 0.5 µm CMOS technology. It contains configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources programmable via SRAM configuration bits loaded at power-up.

It supports IEEE Std 1149.1 (JTAG) boundary-scan testing and in-system programming via dedicated configuration pins. Configuration is typically performed using a serial PROM or microprocessor-controlled parallel mode.

FAQ

What is the maximum operating frequency supported by the XC4003E-4PC84C?

The XC4003E-4PC84C does not specify a single maximum clock frequency due to path-dependent timing. Its -4 speed grade guarantees a 15 ns worst-case propagation delay through a configurable logic block (CLB), enabling system clock frequencies up to approximately 33 MHz for simple register-to-register paths. Actual achievable frequency depends on design topology, routing, and I/O timing constraints - verified via Xilinx Foundation or Alliance software timing analysis.

Does the XC4003E-4PC84C support in-system programming?

Yes, the XC4003E-4PC84C supports in-system programming via its JTAG port (TCK/TMS/TDI/TDO) compliant with IEEE Std 1149.1. Configuration data can be loaded dynamically using boundary-scan instructions, allowing field updates without removing the device. However, configuration is volatile - XC4003E-4PC84C requires external non-volatile storage (e.g., serial PROM) for automatic reload at power-up.

Is the XC4003E-4PC84C pin-compatible with other XC4000E family members in PLCC-84?

XC4003E-4PC84C shares the same PLCC-84 pinout with XC4004E-4PC84C and XC4005E-4PC84C, including identical power, ground, I/O, JTAG, and configuration pin assignments. This enables direct substitution within the same speed grade for designs where increased gate count is acceptable. Always verify timing closure and configuration bitstream compatibility before replacement.

What configuration modes does the XC4003E-4PC84C support?

The XC4003E-4PC84C supports Master Serial, Slave Serial, and Slave Parallel configuration modes. In Master Serial mode, it drives CCLK and reads configuration data from an attached serial PROM. In Slave modes, an external controller (e.g., microprocessor) provides CCLK and configuration data via dedicated pins. JTAG mode allows configuration and boundary-scan testing without requiring dedicated configuration hardware.

Can the XC4003E-4PC84C operate with mixed voltage interfaces?

No, the XC4003E-4PC84C is a single-supply 5 V device with 5 V-tolerant I/Os only. It does not support mixed-voltage operation (e.g., 3.3 V core with 5 V I/O) or internal voltage translation. All I/Os and internal logic operate at 5 V ±5%, and interfacing with lower-voltage devices requires external level-shifting circuitry to avoid damage or incorrect logic thresholds.
