Applications
The XC3S50-4PQG208C suits embedded control and interface bridging applications where a small, low-cost FPGA is needed. Its 173 I/O pins and 50,000 gates make it practical for glue logic replacement, UART or SPI protocol conversion, and sensor data aggregation in industrial and consumer designs. The 208-pin PQFP form factor is compatible with standard through-hole-compatible footprints used in cost-sensitive production boards.

Frequently Asked Questions
How many user I/O pins does the XC3S50-4PQG208C provide, and what voltage levels do they support?
The XC3S50-4PQG208C provides 173 user I/O pins in the 208-pin PQFP package. The device operates from a 3.3 V core supply, and I/O banks support multiple voltage standards including LVCMOS33, LVCMOS25, and LVTTL, allowing direct interfacing with 2.5 V and 3.3 V peripheral devices without additional level shifters.
Which embedded clock management features does the XC3S50-4PQG208C include?
The XC3S50-4PQG208C includes 4 Digital Clock Manager (DCM) blocks that support clock multiplication, division, and phase shifting. Each DCM can synthesize output frequencies across a range dictated by the input clock, enabling designers to generate multiple derived clocks from a single 50 MHz or 100 MHz reference without external PLLs.
When is XC3S50-4PQG208C a better choice than a larger Spartan-3 device such as XC3S200?
When the design logic fits within 1,728 cells and 50,000 gates, the XC3S50-4PQG208C offers a lower unit cost and smaller 208-pin PQFP footprint compared to the XC3S200. For glue logic, protocol bridges, or simple state machines where resource utilization stays below 80%, the XC3S50 avoids paying for unused capacity and simplifies board layout with fewer decoupling capacitors needed.
What is the on-chip distributed RAM capacity available in the XC3S50-4PQG208C?
The XC3S50-4PQG208C provides 12,288 bits of distributed SelectRAM implemented across its logic cell array. This RAM is accessible at full clock speed and can be configured as single-port or dual-port memory, supporting widths such as 16x8 or 32x4 arrangements to store look-up tables, FIFOs, or small coefficient arrays within the FPGA fabric.
