Product details
Overview
XC3S1500-4FG456I from AMD (formerly Xilinx) is a Spartan-3 FPGA with 1,474,560 system gates, 116 I/O pins, and a -4 speed grade operating at up to 333 MHz logic performance in the 456-pin Fine-Pitch Ball Grid Array (FBGA) package. It integrates 128 embedded 18×18 multipliers and supports SelectIO™ standards including LVCMOS, LVTTL, PCI, and HSTL.
For engineers reviewing the XC3S1500-4FG456I datasheet, pinout, applications, or equivalent options, key selection considerations include I/O voltage flexibility (1.2 V to 3.3 V), distributed RAM capacity (576 Kbits), and support for JTAG boundary-scan testing per IEEE 1149.1.
Technical Context
The XC3S1500-4FG456I implements a configurable logic block (CLB) architecture with four 3-input LUTs and eight flip-flops per CLB, enabling high-density synchronous logic implementation. It includes dedicated carry logic for fast arithmetic and supports dual-edge clocking for efficient register utilization.
Configuration is performed via Master Serial mode using an external PROM or through JTAG, with internal startup circuitry managing power-on reset and configuration sequencing. The device supports full IEEE 1149.1 boundary-scan testing and features programmable I/O drive strength (2 mA to 24 mA) and slew rate control.

FAQ
What is the maximum operating frequency of the XC3S1500-4FG456I?
The XC3S1500-4FG456I has a -4 speed grade, guaranteeing timing closure for logic paths operating up to 333 MHz under worst-case industrial temperature and voltage conditions. Actual achievable frequency depends on design topology, placement, and routing, but the device's dedicated carry chain and fast LUTs support sub-3 ns critical path delays in typical implementations of the XC3S1500-4FG456I.
Does the XC3S1500-4FG456I support JTAG boundary-scan testing?
Yes, the XC3S1500-4FG456I fully complies with IEEE 1149.1 and supports JTAG boundary-scan testing for PCB-level interconnect verification. Pins TCK, TMS, TDI, and TDO are dedicated for this function, and the device includes internal scan chains covering I/O buffers and configuration logic-enabling in-circuit validation without requiring the XC3S1500-4FG456I to be operational.
What configuration methods are supported by the XC3S1500-4FG456I?
The XC3S1500-4FG456I supports Master Serial, Slave Serial, and JTAG configuration modes. In Master Serial mode, it drives CCLK and reads bitstream from an external PROM; JTAG mode enables in-system programming and debugging. All modes use the same XC3S1500-4FG456I configuration logic and retain full functionality regardless of method selected.
Can the XC3S1500-4FG456I operate with mixed I/O voltages on different banks?
Yes, the XC3S1500-4FG456I features eight independently powered I/O banks, each supporting VCCO from 1.2 V to 3.3 V. This allows simultaneous interfacing with 1.8 V sensors, 3.3 V microcontrollers, and 2.5 V memory-without level shifters-as long as each bank's VCCO matches the connected peripheral's I/O voltage, a capability confirmed in the XC3S1500-4FG456I datasheet.
Is the XC3S1500-4FG456I still in active production?
The XC3S1500-4FG456I is in continued production under AMD's longevity program for industrial and aerospace customers. While no new design wins are encouraged, AMD maintains committed supply for existing programs with documented lifecycle requirements, and Aetrix Electronics stocks the XC3S1500-4FG456I with full traceability and extended availability planning.
