Product details
Overview
XCS40-3PQ240C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 40,000 system gates, 240-pin PQFP package, 3.3 V I/O voltage, and -3 speed grade (12 ns CLB propagation delay). It serves as a reconfigurable logic fabric in industrial control interfaces requiring deterministic timing and moderate gate count.
For engineers reviewing the XCS40-3PQ240C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (180 user I/Os), configuration mode (serial PROM or parallel slave), JTAG boundary-scan support, and compatibility with Xilinx Foundation/ISE design tools.
Technical Context
The XCS40-3PQ240C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM (up to 256 bits per CLB), and dedicated carry logic for arithmetic functions. It supports synchronous and asynchronous reset, clock enable, and three-state bus interfacing.
Configuration occurs via master serial, slave serial, or slave parallel modes using external PROM or microprocessor. Boundary-scan testing complies with IEEE Std 1149.1 (JTAG), enabling in-system verification and programming without dedicated test fixtures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 40,000 system gates - supports medium-complexity glue logic, protocol bridging, and state-machine control. |
| I/O Count | 180 user-configurable I/Os - enables direct connection to microcontrollers, ADCs, and display drivers without external bus buffers. |
| Speed Grade | -3 (12 ns CLB tPD) - guarantees maximum 83 MHz toggle rate in critical paths under worst-case conditions. |
| VCCIO | 3.3 V ± 0.3 V - compatible with LVTTL and LVCMOS33 interface standards; requires separate 3.3 V supply rail. |
| Configuration Mode | Master/Slave Serial or Slave Parallel - allows flexible boot sources including Xilinx XC18V00 PROM or microcontroller-controlled loading. |
| JTAG Support | IEEE 1149.1 compliant - enables boundary-scan testing, in-circuit programming, and debug visibility without additional test pins. |
Pinout & Package
240-pin Plastic Quad Flat Pack (PQFP), 32 × 32 mm body, 0.5 mm lead pitch, JEDEC MO-118 standard. RoHS-compliant, Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND / VCC | Power supply reference / I/O power | Dedicated power/ground pairs per quadrant minimize switching noise and ensure signal integrity across 180 I/Os. |
| PROGRAM* | Configuration initialization | Active-low asynchronous reset of configuration memory; must be pulled high after power-up to enable normal operation. |
| DIN | Serial configuration data input | Accepts bitstream from XC18V00 PROM or microcontroller during master serial mode; latched on rising CCLK edge. |
| CCLK | Configuration clock | Drives internal shift registers during configuration; frequency ≤ 25 MHz; sourced externally in master mode. |
| TMS / TDI / TDO / TCK | JTAG test access port | Enables IEEE 1149.1 boundary-scan operations; TCK must be ≤ 10 MHz for reliable scan chain operation. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable CLBs with LUTs and FFs | Provides deterministic combinational and sequential logic implementation without fixed-function constraints. |
| Distributed RAM per CLB | Enables small FIFOs, register files, or state storage without consuming dedicated memory blocks. |
| Three-state bus drivers | Supports shared data bus architectures with bidirectional control, reducing external transceiver count. |
| Programmable I/O standards | Per-pin selectable LVTTL/LVCMOS33 drive strength and slew rate for EMI and timing optimization. |
| Boundary-scan (JTAG) | Reduces test development time and eliminates need for bed-of-nails fixtures in production test. |
Applications
| Industrial Motion Controller | Legacy Bus Interface Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCS40-4PQ240C | Faster -4 speed grade (10 ns CLB tPD); otherwise identical architecture, pinout, and configuration interface. | Required where 100+ MHz toggle rates or tighter setup margins are needed in critical paths. | Select when timing closure fails on XCS40-3PQ240C and board layout cannot be modified. |
| XCS40-3TQ144C | Same -3 speed grade and logic capacity but 144-pin TQFP package (113 user I/Os); smaller footprint, lower I/O count. | Suitable for space-constrained designs with ≤113 I/O requirements and no need for full 180-pin interface. | Choose when PCB area is limited and I/O count reduction is acceptable for cost or routing simplification. |
Compared with XCS40-3PQ240C, the XCS40-4PQ240C offers higher timing margin at identical package and toolchain compatibility, while the XCS40-3TQ144C trades I/O count and thermal performance for compactness-both require no HDL or constraint file changes beyond pin assignment updates.

FAQ
What configuration methods does the XCS40-3PQ240C support?
The XCS40-3PQ240C supports master serial, slave serial, and slave parallel configuration modes. Master serial uses an external PROM (e.g., XC18V00) to drive CCLK and DIN; slave modes allow microprocessor-controlled loading. All modes retain full IEEE 1149.1 JTAG access for debugging and programming. XCS40-3PQ240C does not support internal configuration memory or single-chip boot.
Does the XCS40-3PQ240C support hot-swapping or live I/O reconfiguration?
No, the XCS40-3PQ240C does not support partial reconfiguration or hot-swapping. Configuration is static and occurs only at power-up or upon assertion of PROGRAM*. I/O voltage (3.3 V) and drive strength are set at configuration time and cannot be altered dynamically. XCS40-3PQ240C requires full reconfiguration to change logic functionality or I/O settings.
What is the operating temperature range for the XCS40-3PQ240C?
The XCS40-3PQ240C is rated for commercial temperature range: 0 °C to +70 °C ambient. It is not specified for industrial (-40 °C to +85 °C) or extended temperature operation. Thermal derating applies above 70 °C; junction temperature must remain below 125 °C. XCS40-3PQ240C datasheets do not guarantee timing or functionality outside the commercial range.
Can the XCS40-3PQ240C be programmed via JTAG alone without external PROM?
Yes, the XCS40-3PQ240C can be configured exclusively via JTAG using IEEE 1149.1 boundary-scan instructions (ISC_ENABLE, ISC_PROGRAM, ISC_NOOP). This method loads configuration bitstream directly into SRAM cells and is commonly used for prototyping and in-system programming. XCS40-3PQ240C retains configuration only while powered; power loss requires reprogramming.
Is the XCS40-3PQ240C pin-compatible with newer Spartan families like Spartan-3 or Spartan-6?
No, the XCS40-3PQ240C is not pin-compatible with Spartan-3 or Spartan-6 devices. It belongs to the legacy Spartan-XL architecture with distinct I/O cell structure, configuration protocol, and power requirements. Migration requires complete PCB redesign, HDL rewrite, and toolchain transition. XCS40-3PQ240C has no drop-in replacement in later Spartan generations.
