It integrates 128 embedded 18×18 multipliers and supports SelectIO standards including LVCMOS, LVTTL, and SSTL. It is used in industrial control logic and reconfigurable digital signal processing subsystems.
For engineers reviewing the XC3S1500-5FG676C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count, multiplier resource density, configuration interface (JTAG/Slave Serial), and thermal performance in compact PCB layouts.
Technical Context
The XC3S1500-5FG676C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, block RAM (576 Kbits), and dedicated digital clock managers (DCMs). Its DCMs provide phase-matched clock synthesis, duty-cycle correction, and frequency synthesis up to 320 MHz.
Configuration is performed via Master Serial, Slave Serial, or JTAG modes using external PROM or processor-controlled interfaces. The device supports IEEE 1149.1 boundary-scan testing and includes internal pull-up resistors on unused I/O pins.

FAQ
What is the maximum operating frequency of the XC3S1500-5FG676C?
The XC3S1500-5FG676C has a -5 speed grade specifying guaranteed timing performance up to 320 MHz for DCM-synthesized clocks. Internal logic paths achieve typical maximum frequencies of 250–280 MHz depending on routing and resource utilization. The actual achievable system clock depends on design constraints, place-and-route results, and I/O standard selection.
Does the XC3S1500-5FG676C support JTAG programming and debugging?
Yes, the XC3S1500-5FG676C fully supports IEEE 1149.1 JTAG boundary-scan for programming, debugging, and in-circuit verification. TCK, TMS, TDI, and TDO pins are dedicated for this interface, and the device enables configuration through JTAG mode without requiring external PROM or microcontroller bootloading.
What configuration methods are supported by the XC3S1500-5FG676C?
The XC3S1500-5FG676C supports Master Serial, Slave Serial, and JTAG configuration modes. In Master Serial mode, it drives an external PROM; in Slave Serial, it accepts configuration data from a microcontroller; and JTAG allows direct programming via standard debug tools. All modes use the same bitstream format.
Can the XC3S1500-5FG676C operate in extended temperature ranges?
No, the XC3S1500-5FG676C is rated for commercial temperature range only (0°C to +85°C ambient). It is not qualified for industrial (-40°C to +100°C) or automotive grades. Thermal derating and board-level cooling must be applied if ambient exceeds +85°C during sustained operation.
How many differential I/O pairs does the XC3S1500-5FG676C support?
The XC3S1500-5FG676C supports up to 56 differential I/O pairs (LVDS, RSDS, BLVDS) when configured in compatible I/O standards. Each pair uses two adjacent pins within the same I/O bank, and termination resistors must be externally placed. Full differential support requires proper VCCO and VREF assignment per bank.
