AMD XC4010-5PQ208C

Overview

XC4010-5PQ208C from Xilinx is a third-generation Field-Programmable Gate Array (FPGA) with 10,000 usable gates, 400 Configurable Logic Blocks (CLBs), 1,120 flip-flops, and 160 I/O pins in a 208-pin Plastic Quad Flat Package (PQFP). It supports system clock rates up to 50 MHz and features on-chip RAM, fast carry logic, and eight global low-skew clock networks - deployed in high-speed digital signal processing and microprocessor peripheral interface designs.

For engineers reviewing the XC4010-5PQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count (400), max I/O (160), propagation delay (7 ns for 9-bit parity), RAM bit capacity (12,800), and PQ208 package compatibility with industrial PCB layouts.

Technical Context

The XC4010-5PQ208C implements a symmetric CLB architecture with two independent 4-input function generators (F' and G') plus a third 3-input H' generator, enabling single-block implementation of 5-variable logic or 9-input functions. Each CLB provides four outputs (X, Y, XQ, YQ) and dual edge-triggered D-flip-flops with programmable asynchronous set/reset.

Routing includes eight global low-skew nets, double-length and single-length interconnect lines, and four edge-mounted wide decoders (up to 60 inputs per side). IOBs support programmable slew rate, input delay compensation, and 12 mA sink current per output - with adjacent outputs wire-ANDable for 24 mA drive.

Key Specifications

Pinout & Package

XC4010-5PQ208C uses a 208-pin Plastic Quad Flat Package (PQFP) with 52 pins per side, 0.5 mm lead pitch, and exposed thermal pad. Pinout follows Xilinx XC4000 family standard layout: power (VCC, GND), configuration (INIT, PROGRAM, CCLK), global clocks (GCK0–GCK7), and bidirectional IOBs grouped by quadrant.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and developed the XC4000 family as its third-generation high-density programmable logic platform.

The XC4000 family was designed for reconfigurable digital systems demanding higher logic density, on-chip memory, and faster interconnect than second-generation XC3000 devices - targeting embedded control, signal processing, and protocol adaptation.

FAQ

What is the maximum guaranteed system clock frequency for XC4010-5PQ208C?

The XC4010-5PQ208C is rated for synchronous system clock rates up to 50 MHz under worst-case conditions (commercial temperature/voltage). This is validated by Xilinx timing analysis using the -5 speed grade, which guarantees 7 ns CLB propagation delay and 20.5 ns 16-bit adder carry delay. The XC4010-5PQ208C achieves this using eight global low-skew clock networks and optimized CLB carry logic - not dependent on external clock conditioning.

Does XC4010-5PQ208C support in-system reconfiguration?

Yes, XC4010-5PQ208C supports unlimited in-system reconfiguration via slave serial or peripheral modes. Configuration data can be written into the device through the CCLK and DIN pins under control of an external microcontroller, enabling dynamic hardware updates. The XC4010-5PQ208C retains full functionality during reconfiguration, and the INIT pin signals completion or CRC error - critical for field-upgradable embedded systems.

How much on-chip RAM does XC4010-5PQ208C provide, and how is it structured?

XC4010-5PQ208C provides 12,800 bits of distributed RAM, implemented by configuring CLB function generators as memory arrays. Each CLB supports either 16×2-bit or 32×1-bit RAM with 5.5 ns read access time - identical to logic propagation delay. RAM is distributed across all 400 CLBs, enabling concurrent access to multiple small buffers (e.g., FIFOs, status registers) without contention, unlike monolithic block RAM architectures.

Can XC4010-5PQ208C drive standard TTL loads directly?

Yes, XC4010-5PQ208C can drive standard TTL loads directly: each output sinks 12 mA at VOH = 2.4 V (min), meeting TTL input low-level current requirements. Two adjacent outputs can be wire-ANDed to sink 24 mA - sufficient for driving short PCB traces or multiple TTL inputs. Unlike earlier FPGAs, XC4010-5PQ208C eliminates need for external buffer ICs in most industrial control interfaces.

Is boundary-scan testing supported on XC4010-5PQ208C?

Yes, XC4010-5PQ208C includes full IEEE 1149.1-compliant boundary-scan logic embedded within its IOBs. The JTAG TAP controller supports instruction register scan, data register scan, EXTEST, SAMPLE/PRELOAD, and BYPASS operations - enabling board-level interconnect testing, in-system programming, and debugging without physical probe access. This capability is factory-configured and requires no user logic resources.
