Product details
Overview
XCS30-3VQ100C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 30,000 system gates, 100-pin VQFP package, 217 logic cells, 176 I/O pins, and 1.2 V core voltage. It targets low-cost, high-volume embedded control and interface bridging in industrial PLCs and serial protocol adapters.
For engineers reviewing the XCS30-3VQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, core voltage tolerance, configuration mode support (Master Serial), and JTAG boundary-scan compliance for production testability.
Technical Context
The XCS30-3VQ100C implements a configurable logic block (CLB) architecture with dedicated carry logic and distributed RAM. It supports IEEE 1149.1 JTAG boundary-scan and uses internal configuration memory loaded via serial PROM or microprocessor interface.
It operates at -3 speed grade (max 100 MHz system clock), requires external 3.3 V I/O supply and 1.2 V core supply, and supports LVCMOS25/LVTTL I/O standards with programmable slew rate and drive strength per bank.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 217 - defines maximum combinational/sequential logic capacity for state machines or data path logic |
| I/O Pins | 176 - supports multi-bank voltage domain isolation and mixed-voltage interfacing |
| Core Voltage | 1.2 V ± 3% - mandates tight-regulation DC-DC converter with <50 mV ripple for stable operation |
| Speed Grade | -3 - guarantees timing closure up to 100 MHz system clock frequency under worst-case conditions |
| Configuration Mode | Master Serial - enables boot from external SPI PROM without host processor involvement |
| JTAG Support | IEEE 1149.1 compliant - provides full boundary-scan test access for PCB assembly verification |
Pinout & Package
Package: 100-pin Very Thin Quad Flat Pack (VQFP), 14 mm × 14 mm, 0.5 mm pitch, thermally enhanced with exposed pad (non-electrical).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCK0–GCK3 | Global Clock Input | Dedicated low-skew routing to all CLBs; required for synchronous design timing integrity |
| TCK/TMS/TDI/TDO | JTAG Test Access Port | Enables in-circuit programming and IEEE 1149.1 boundary-scan diagnostics |
| HSWAP_EN | Hot-Swap Enable | Controls I/O weak pull-up during power-up; must be tied HIGH for normal operation |
| M0–M2 | Mode Select | Configures startup mode (Master Serial, Slave Serial, Boundary Scan); hardwired at power-on |
| VCCO_0–VCCO_3 | I/O Bank Supply | Independent 3.3 V supplies per I/O bank enable mixed-voltage interface (e.g., 3.3 V + 2.5 V) |
Key Features
| Feature | Design Value |
|---|---|
| Distributed RAM | Each CLB contains 16-bit RAM usable as shift register or small lookup table - reduces external memory need in FIFO or buffering logic |
| Carry Chain Logic | Fast arithmetic chain across CLBs - enables efficient counter, adder, and accumulator implementation without LUT resource penalty |
| Programmable I/O Drive | Selectable 4/8/12/16 mA drive strength per pin - balances signal integrity and EMI in noisy industrial environments |
| Three-State Control | Per-pin tristate enable with independent control - supports shared bus arbitration in multi-master systems |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCS30-4VQ100C | Faster -4 speed grade (125 MHz max clock), identical pinout and logic resources | Better suited for higher-frequency data sampling or tighter timing margins | Select when timing closure fails at -3 grade or when future-proofing for clock scaling |
| XCS25-3VQ100C | Lower density (25K gates, 176 I/O, 181 CLBs), same package and voltage | Reduced logic capacity limits complex state machines or wide datapaths | Choose for cost-sensitive designs where 217 CLBs exceed requirement and BOM cost is critical |

FAQ
What is the configuration method supported by XCS30-3VQ100C?
The XCS30-3VQ100C supports Master Serial configuration mode, allowing automatic loading of bitstream from an external SPI PROM at power-up. It also supports Slave Serial and JTAG modes for programming and debugging. The M0–M2 pins determine the active mode at reset, and no external processor is required for Master Serial operation. This makes XCS30-3VQ100C ideal for standalone embedded systems with minimal boot components.
Does XCS30-3VQ100C require external configuration memory?
Yes, XCS30-3VQ100C does not include on-chip nonvolatile configuration memory. It relies on external SPI PROM or microprocessor-controlled configuration via JTAG or Slave Serial interface. The device retains its programmed logic only while powered; reconfiguration occurs at each power cycle unless persistent storage is provided externally. This behavior is inherent to the XCS30-3VQ100C architecture and applies regardless of configuration mode selected.
What I/O standards are supported by XCS30-3VQ100C?
XCS30-3VQ100C supports LVCMOS25, LVCMOS33, and LVTTL I/O standards across four independently powered I/O banks. Each bank accepts 3.3 V VCCO, and input thresholds are compatible with both 2.5 V and 3.3 V signaling. Programmable drive strength (4–16 mA) and slew rate control per pin allow optimization for noise immunity or edge rate in mixed-signal industrial environments where XCS30-3VQ100C is commonly deployed.
Can XCS30-3VQ100C operate with a single 3.3 V supply?
No, XCS30-3VQ100C requires two separate supplies: 1.2 V ± 3% for the core logic and 3.3 V for I/O banks. Using only 3.3 V on VCCINT will damage the device. A dedicated low-noise 1.2 V regulator with adequate decoupling is mandatory. This dual-supply requirement is specified in the XCS30-3VQ100C datasheet and reflects the architectural separation of core and I/O domains to optimize power and signal integrity.
Is JTAG boundary-scan supported on XCS30-3VQ100C?
Yes, XCS30-3VQ100C fully complies with IEEE 1149.1 JTAG boundary-scan. The TCK, TMS, TDI, and TDO pins provide access to internal scan chains for interconnect testing, in-system programming, and debug visibility. This capability is factory-tested and documented in the XCS30-3VQ100C Technical Reference Manual, enabling automated PCB test coverage without physical probe access.
