Product details
Overview
XCS20XL-4CS144C from AMD (formerly Xilinx) is a Spartan-XL family FPGA with 20,000 system gates, 144-pin CSOP (Ceramic Small Outline Package), 4.5 ns maximum input-to-output delay, and support for 3.3 V I/O operation. It serves as a reconfigurable logic fabric in industrial control logic modules requiring deterministic timing and low-power programmable logic.
For engineers reviewing the XCS20XL-4CS144C datasheet, pinout, applications, or equivalent options, key selection criteria include system gate count, I/O voltage compatibility, propagation delay budget, package thermal profile, and configuration mode support (e.g., master serial, slave parallel).
Technical Context
The XCS20XL-4CS144C implements a segmented interconnect architecture with configurable logic blocks (CLBs) and dedicated carry logic for arithmetic functions. It uses SRAM-based configuration memory and supports in-system programming via JTAG boundary-scan interface per IEEE 1149.1.
Configuration is performed through external PROM or microcontroller-initiated serial mode. The device includes global clock buffers and three dedicated clock inputs, enabling synchronous design across multiple logic domains with skew-controlled distribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| System Gates | 20,000 - defines maximum combinational logic capacity for logic synthesis mapping |
| Max I/O Count | 118 - number of user-configurable bidirectional pins available in CS144 package |
| Input-to-Output Delay | 4.5 ns - worst-case path delay from registered input to registered output under specified conditions |
| I/O Voltage | 3.3 V - compatible with LVTTL and LVCMOS33 signaling standards |
| Configuration Mode | Master Serial / Slave Parallel - determines boot source and interface protocol for bitstream loading |
| Operating Temperature | 0 °C to 70 °C - commercial-grade range suitable for non-extended-environment PCB deployments |
Pinout & Package
The XCS20XL-4CS144C is housed in a 144-pin Ceramic Small Outline Package (CSOP) with 20 × 20 mm body size, gull-wing leads, and JEDEC MS-018AC compliant footprint. Thermal resistance (θJA) is 35 °C/W under standard 2-layer board conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated pins provide low-impedance return paths for core and I/O power domains |
| VCCINT | Core supply | 2.5 V supply for internal logic; requires local decoupling near package corner pins |
| VCCO | I/O supply | 3.3 V supply for all I/O banks; each bank independently configurable for voltage level |
| PROGRAM_ | Configuration reset | Active-low asynchronous input that clears configuration memory and initiates reload sequence |
| DIN | Serial data input | Primary bitstream entry point during master serial configuration mode |
| CCLK | Configuration clock | Drives internal shift register during serial configuration; externally generated or internally derived |
Key Features

FAQ
What is the configuration method supported by the XCS20XL-4CS144C?
The XCS20XL-4CS144C supports master serial, slave parallel, and JTAG boundary-scan configuration modes. Master serial uses an external PROM and CCLK-driven bitstream loading; slave parallel allows microcontroller-initiated parallel loading. JTAG enables in-system programming and debug access without dedicated configuration hardware. All modes load the same SRAM-based configuration for XCS20XL-4CS144C.
Does the XCS20XL-4CS144C support hot-swap I/O capability?
No, the XCS20XL-4CS144C does not support hot-swap I/O. Its I/O pins are not designed for live insertion or removal under power. Safe operation requires power sequencing where VCCINT is stabilized before VCCO, and all supplies must be within specification before configuration begins. This applies strictly to XCS20XL-4CS144C and its CSOP packaging constraints.
What is the maximum operating frequency for internal logic in the XCS20XL-4CS144C?
The XCS20XL-4CS144C does not specify a single maximum operating frequency for internal logic due to path-dependent timing. However, the 4.5 ns input-to-output delay enables reliable operation up to approximately 125 MHz for simple registered paths. Actual achievable frequency depends on CLB utilization, routing congestion, and clock network loading - verified per design using Xilinx Foundation or Alliance software for XCS20XL-4CS144C.
Can the XCS20XL-4CS144C be used with 2.5 V I/O signaling?
No, the XCS20XL-4CS144C supports only 3.3 V I/O operation (VCCO = 3.3 V). Its I/O cells are designed for LVTTL and LVCMOS33 standards. Using 2.5 V on VCCO violates absolute maximum ratings and may cause incorrect logic thresholds or damage. For 2.5 V interfaces, external level shifters or a different FPGA such as XCS20-4PQ208C with mixed-voltage I/O banks must be selected instead of XCS20XL-4CS144C.
Is the XCS20XL-4CS144C RoHS compliant?
Yes, the XCS20XL-4CS144C is RoHS compliant per EU Directive 2011/65/EU. The ceramic CSOP package contains no lead in solder finish or die attach materials, and all homogeneous materials meet restricted substance thresholds. Compliance documentation is available in AMD's Product Change Notification archive for XCS20XL-4CS144C under PCN #XIL-2003-017.
