AMD XC4013-6PQ240C

Overview

XC4013-6PQ240C from Xilinx is a third-generation Field-Programmable Gate Array (FPGA) with 13,000 usable gates, 576 Configurable Logic Blocks (CLBs), and 1,536 flip-flops. It features on-chip RAM (18,432 bits), eight global low-skew clock networks, and wide-edge decoders supporting up to 72 inputs per device - optimized for high-speed address decoding in microprocessor systems.

For engineers reviewing the XC4013-6PQ240C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count (576), I/O count (192), -6 speed grade (max 60 MHz system clock), PQ240 package compatibility, and support for IEEE 1149.1 boundary-scan testing.

Technical Context

The XC4013-6PQ240C implements a symmetric CLB architecture with two independent 4-input function generators (F' and G') plus a third 3-input generator (H'), enabling single-block implementation of 5–9 variable logic functions. Each CLB provides four outputs (X, Y, XQ, YQ), dual edge-triggered D flip-flops with programmable asynchronous set/reset, and dedicated fast-carry logic for arithmetic acceleration.

Its IOB structure supports programmable input setup time, slew-rate control, 24 mA sink current per output (pairable to 48 mA), and IEEE 1149.1-compliant boundary-scan. The device uses sub-micron CMOS technology and supports six configuration modes including master serial, slave parallel, and peripheral synchronous.

Manufacturer

Xilinx, now part of AMD, pioneered commercial FPGAs and developed the XC4000 family as its third-generation high-density programmable logic platform.

The XC4000 family was designed for reconfigurable digital systems demanding high gate count, on-chip memory, and deterministic timing - targeting industrial control, communications infrastructure, and military/aerospace applications.

FAQ

What is the maximum guaranteed system clock frequency for XC4013-6PQ240C?

The XC4013-6PQ240C carries the -6 speed grade, guaranteeing reliable synchronous operation up to 60 MHz. This rating assumes worst-case voltage (3.135 V), temperature (85°C), and process corner conditions. Measured toggle rates exceed 125 MHz, but system-level timing closure depends on routing congestion and logic depth - actual achievable clock frequency must be verified using Xilinx Foundation or Alliance software timing analysis tools with the final placed-and-routed design.

Does XC4013-6PQ240C support in-system reconfiguration?

Yes, XC4013-6PQ240C supports unlimited in-system reconfiguration via its slave serial or slave parallel configuration modes. Configuration data can be loaded dynamically through a microcontroller or host processor using the INIT, PROGRAM, and DONE signals. The device retains its configuration in volatile SRAM cells and requires reloading after power cycle - no external nonvolatile memory is needed for reprogramming, though PROMs are commonly used for power-on initialization.

How many bits of RAM does XC4013-6PQ240C provide, and how is it structured?

XC4013-6PQ240C provides 18,432 bits of on-chip RAM, implemented as distributed memory within its 576 CLBs. Each CLB's F' and G' function generators can be configured as either a 16×2-bit or 32×1-bit synchronous RAM block. Read access time matches logic propagation delay (~5.5 ns); write cycle time is ~8 ns. This RAM is not contiguous - it is scattered across the array - making it ideal for small buffers, status registers, and pipeline stages rather than large frame buffers.

Is XC4013-6PQ240C pin-compatible with other XC4000 family devices in PQ240 packaging?

No - XC4013-6PQ240C is not pin-compatible with smaller XC4000 devices (e.g., XC4005, XC4006) in the same PQ240 package. While all XC4000 PQ240 variants share the same mechanical footprint and pin count (240), their I/O assignments, VCC/GND pin allocations, and dedicated function pin locations (e.g., JTAG, configuration, global clocks) differ significantly between densities. Migration requires PCB redesign and netlist adaptation; only speed-grade variants (-5/-6/-7) of the exact same density (XC4013) are pin-identical.

What configuration modes does XC4013-6PQ240C support, and which are most commonly used?

XC4013-6PQ240C supports six configuration modes: Master Serial, Master SelectMAP, Slave Serial, Slave Parallel, Peripheral Synchronous, and Peripheral Asynchronous. Master Serial (using on-chip oscillator driving external serial PROM) is most common for cost-sensitive applications. Slave Parallel is preferred for high-speed reconfiguration by microcontrollers. Peripheral Synchronous (8-bit wide) is widely adopted in embedded systems requiring fast bitstream loading from flash memory with handshake control.
