Product details
Overview
XC3S50-4VQG100C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 50,000 system gates, 1728 logic cells, 120 I/O pins, and configured in a 100-pin VQFP package for embedded control and interface bridging applications.
For engineers reviewing the XC3S50-4VQG100C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count, logic cell density, VQFP thermal profile, and -4 speed grade timing compliance in industrial temperature range.
Technical Context
The XC3S50-4VQG100C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated multipliers. It supports SelectIO standards including LVCMOS, LVTTL, and PCI up to 33 MHz.
Configuration is performed via master serial mode using external PROM or JTAG boundary-scan. The device operates at 1.2 V core voltage and 3.3 V I/O voltage, with internal digital clock managers (DCMs) supporting frequency synthesis and phase alignment.

FAQ
What is the maximum operating frequency of the XC3S50-4VQG100C?
The XC3S50-4VQG100C has a -4 speed grade, guaranteeing a maximum system clock frequency of 280 MHz for CLB-to-CLB paths under industrial temperature conditions (0°C to +85°C). This rating is verified per Xilinx DS099 and applies to synchronous logic paths meeting setup/hold timing constraints.
Does the XC3S50-4VQG100C support JTAG programming?
Yes, the XC3S50-4VQG100C supports IEEE 1149.1 JTAG boundary-scan for configuration, debugging, and in-system programming. Pins TCK, TMS, TDI, and TDO are dedicated for this interface and function independently of the main configuration mode.
What power supplies are required for the XC3S50-4VQG100C?
The XC3S50-4VQG100C requires two regulated supplies: 1.2 V ±3% for the core (VCCINT) and 3.3 V for I/O banks (VCCO). Separate decoupling capacitors per bank and core are mandatory per Xilinx UG331 to ensure stable configuration and signal integrity.
Is the XC3S50-4VQG100C RoHS compliant?
Yes, the XC3S50-4VQG100C is RoHS-6 compliant and lead-free, with matte tin finish on all leads. Compliance is documented in AMD's Product Change Notification PCN-2021-001 and applies to all production lots shipped after Q3 2021.
Can the XC3S50-4VQG100C be used in automotive applications?
The XC3S50-4VQG100C is qualified for industrial temperature range (0°C to +85°C) and is used in automotive diagnostic tools and non-safety-critical subsystems. It is not AEC-Q100 qualified and should not be deployed in engine bay or safety-critical ADAS functions without additional system-level qualification.
