Product details
Overview
XC2S100-5PQ208I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 100,000 system gates, 1728 logic cells, and 128 I/O pins in a 208-pin PQFP package. It operates at -5 speed grade (5 ns CLB delay), supports 3.3 V I/O, and features SelectRAM+ memory blocks for embedded data storage. It is used in industrial control logic and digital signal preprocessing.
For engineers reviewing the XC2S100-5PQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, CLB delay, configuration interface (JTAG/Slave Serial), RAM block depth, and thermal performance in constrained PCB layouts.
Technical Context
The XC2S100-5PQ208I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM (16-bit wide × 32 deep per CLB), and dedicated carry logic for arithmetic. It includes eight global clock buffers and supports multi-voltage I/O banks (3.3 V only).
Configuration is performed via JTAG boundary-scan or Slave Serial mode using an external PROM. The device lacks internal oscillator or analog functions and requires external configuration memory and power sequencing support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 100,000 system gates - defines maximum combinational logic density for gate-equivalent design mapping |
| CLB Count | 1728 CLBs - determines parallel logic resource availability for pipelined or parallel architectures |
| I/O Pins | 128 user I/Os - supports medium-complexity peripheral interfacing with banked voltage assignment |
| Speed Grade | -5 (5 ns CLB propagation delay) - sets worst-case timing closure margin for 200 MHz synchronous logic |
| RAM Blocks | SelectRAM+ distributed RAM (16×32 per CLB) - enables small FIFOs, state tables, or coefficient storage without external memory |
| Package | PQ208 (208-pin Plastic Quad Flat Pack, 28×28 mm, 0.5 mm pitch) - requires standard QFP reflow profile and 0.3 mm trace/space routing |
Pinout & Package
PQ208 is a 208-pin plastic quad flat pack with gull-wing leads, 28 mm × 28 mm body, 0.5 mm lead pitch, and JEDEC MS-026 compliant footprint. Thermal pad is not present; thermal dissipation relies on PCB copper area and airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCK0–GCK7 | Global Clock Input | Dedicated low-skew inputs for clock distribution to all CLBs and I/Os |
| TCK/TMS/TDI/TDO | JTAG Boundary-Scan Interface | Enables in-system programming, debug, and IEEE 1149.1 compliance testing |
| PROGRAM_B | Active-Low Configuration Initiate | Resets configuration logic and clears SRAM contents on falling edge |
| DIN | Serial Configuration Data Input | Accepts bitstream during Slave Serial mode; tied high when unused |
| INIT_B | Configuration Status Output | Open-drain active-low signal indicating configuration completion or error |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Logic Blocks (CLBs) | Each CLB contains two 4-input LUTs + 2 flip-flops - supports efficient implementation of synchronous state machines and arithmetic units |
| SelectRAM+ Memory | Distributed 16×32 RAM per CLB - eliminates need for external SRAM in small buffer or lookup table applications |
| Multi-Voltage I/O Banks | 3.3 V only - simplifies power delivery but requires level-shifting for 5 V or 2.5 V peripherals |
| JTAG & Slave Serial Configuration | Two independent configuration modes - enables field updates via JTAG or cost-effective PROM-based boot |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2S100-6PQ208C | Faster -6 speed grade (4.5 ns CLB delay); commercial temperature range (0°C to 70°C) | Not rated for industrial (-40°C to 100°C) operation; unsuitable for extended ambient environments | Select only if timing margin is critical and operating temperature remains within 0–70°C |
| XC3S100E-4PQ208C | Spartan-3E family; higher logic density (1584 logic cells), 1.2 V core, enhanced DSP slices | Requires different power supply architecture and configuration PROM; not pin-compatible | Choose for new designs needing lower power or improved arithmetic throughput, but expect full PCB and firmware redesign |
Compared with XC2S100-5PQ208I, the -6PQ208C offers tighter timing but sacrifices industrial temperature rating, while the XC3S100E-4PQ208C delivers architectural upgrades at the cost of full hardware incompatibility and revised power delivery.

FAQ
What is the operating temperature range for XC2S100-5PQ208I?
The XC2S100-5PQ208I is specified for industrial temperature operation from –40°C to +100°C. This range ensures reliable functionality in harsh environments such as factory floors or outdoor enclosures. Its thermal design assumes natural convection cooling and standard FR-4 PCB layout with adequate copper pour. The XC2S100-5PQ208I does not require active cooling under typical load conditions.
Does XC2S100-5PQ208I support in-system programming?
Yes, XC2S100-5PQ208I supports in-system programming via its IEEE 1149.1-compliant JTAG interface (TCK/TMS/TDI/TDO pins). This allows configuration bitstream updates without removing the device from the board. The XC2S100-5PQ208I also supports Slave Serial mode for PROM-based boot. Both methods retain full access to internal configuration memory and status registers.
What power supplies are required for XC2S100-5PQ208I?
XC2S100-5PQ208I requires a single 2.5 V supply for core logic and a separate 3.3 V supply for I/O banks. No auxiliary voltages are needed. Power-on sequencing must assert VCCINT before VCCO, with monotonic ramp rates between 0.1 V/ms and 1 V/ms. The XC2S100-5PQ208I draws up to 320 mA on VCCINT and 480 mA on VCCO under full toggle conditions.
Can XC2S100-5PQ208I be used as a drop-in replacement for XC2S100-5PQ208C?
No, XC2S100-5PQ208I is not a drop-in replacement for the commercial-grade XC2S100-5PQ208C. While both share identical pinout and logic resources, the I-grade version has extended temperature qualification, different AC timing parameters, and distinct thermal characterization. Substituting without validation may cause timing violations or reliability issues outside 0–70°C.
What configuration memory devices are compatible with XC2S100-5PQ208I?
XC2S100-5PQ208I supports standard 8-pin SPI PROMs such as Xilinx XC18V02 or Atmel AT17LV010 for Slave Serial configuration. JTAG configuration requires no external memory. The XC2S100-5PQ208I accepts 1.8 V or 3.3 V PROMs depending on VCCO setting, and supports cascaded PROM chains for multi-device systems.
