Product details
Overview
XC3S1400A-4FG484C from AMD (formerly Xilinx) is a Spartan-3A FPGA featuring 1,400,000 system gates, 216 I/O pins, and a -4 speed grade in a 484-pin Fine-Pitch Ball Grid Array (FBGA) package. It integrates 216 configurable logic blocks (CLBs), 12 embedded 18×18 multipliers, and supports 3.3V/2.5V/1.2V I/O standards for industrial control and communication interface applications.
For engineers reviewing the XC3S1400A-4FG484C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, logic capacity, supported voltage standards, embedded multiplier count, and thermal performance in compact PCB layouts.
Technical Context
The XC3S1400A-4FG484C implements a synchronous, SRAM-based architecture with configuration via external PROM or processor-controlled JTAG. Its CLBs contain two 4-input LUTs and flip-flops per slice, enabling efficient implementation of state machines and datapaths. The device includes dedicated carry logic for high-speed arithmetic and supports distributed RAM and shift register functions within logic fabric.
It features 12 embedded 18×18 signed/unsigned multipliers operating up to 250 MHz, and supports LVCMOS, LVTTL, PCI, HSTL, and SSTL I/O standards across 216 user-configurable pins. Configuration memory retention requires continuous power or external reconfiguration on power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 1,400,000 system gates - determines maximum combinational/sequential logic complexity realizable without external logic. |
| I/O Pins | 216 user-configurable I/Os - supports high-pin-count interfaces such as parallel buses, video data paths, or multi-channel ADC/DAC control. |
| Embedded Multipliers | 12 × 18×18-bit - enables fixed-point DSP functions like FIR filtering or motor control algorithms without external math ICs. |
| Speed Grade | -4 - guarantees timing closure up to 250 MHz for critical paths under worst-case industrial temperature and voltage conditions. |
| Package | 484-pin FBGA (23×23 mm, 1.0 mm pitch) - provides high I/O density and thermal dissipation suitable for industrial PCBs with constrained area. |
| Voltage Support | 1.2 V core / 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V I/O - allows direct interfacing with mixed-voltage peripherals without level shifters. |
Pinout & Package
XC3S1400A-4FG484C is housed in a 484-ball fine-pitch BGA (FPBGA) package with 216 user I/Os, 8 global clock inputs, 4 dedicated configuration pins (INIT_B, PROGRAM_B, DONE, CCLK), and power/ground balls distributed across the array for low-noise operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CCLK | Configuration Clock | Drives internal configuration shift registers during master serial or JTAG programming; must be stable before INIT_B deassertion. |
| DONE | Configuration Status Output | Open-drain signal indicating successful configuration completion; pulled high externally to enable downstream logic enablement. |
| PROGRAM_B | Active-Low Configuration Initiate | Resets configuration memory and initiates reconfiguration cycle when pulsed low; asynchronous reset to all internal logic. |
| INIT_B | Configuration Initialization Status | Open-drain output signaling readiness to accept configuration data; asserted low during internal initialization or CRC error. |
| GCLK[0–7] | Global Clock Inputs | Dedicated low-skew routing to all CLBs and block RAM; supports single-ended (LVCMOS/LVTTL) or differential (LVDS) clock sources. |
Key Features
| Feature | Design Value |
|---|---|
