AMD XC4085XL-1BG560C

Overview

XC4085XL-1BG560C from Xilinx is a Field-Programmable Gate Array (FPGA) featuring 8,500 usable logic cells, 176 I/O pins, and 100 kbits of block RAM, configured in a 560-pin Ball Grid Array (BGA) package with 3.3V I/O voltage support for embedded control and digital signal processing applications.

For engineers reviewing the XC4085XL-1BG560C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, RAM capacity, speed grade (-1), and BGA thermal/mechanical compatibility in industrial control and communications hardware.

Technical Context

The XC4085XL-1BG560C implements a configurable logic architecture based on CLBs (Configurable Logic Blocks), each containing two 3-input LUTs and flip-flops, supporting synchronous design with global clock routing and dedicated carry chains for arithmetic functions.

It supports IEEE 1149.1 JTAG boundary-scan testing, operates at 3.3V core and I/O supply, and uses SRAM-based configuration loaded via serial PROM or microprocessor interface - requiring external configuration memory for power-up initialization.

Key Specifications

Pinout & Package

XC4085XL-1BG560C is housed in a 560-pin Fine-Pitch Ball Grid Array (FBGA) package with 27×27 array, 1.27 mm ball pitch, and thermal pad center. Pin functions are organized into banks with dedicated clock, configuration, JTAG, and I/O resources.

Manufacturer

Xilinx, now part of AMD, is a pioneer in programmable logic devices, delivering FPGAs, SoCs, and adaptive compute acceleration platforms since 1984.

The XC4000XL family was engineered for low-power, high-density logic implementation in industrial and communications systems where reconfigurability and I/O flexibility are critical.

FAQ

What is the maximum operating frequency supported by XC4085XL-1BG560C?

The XC4085XL-1BG560C speed grade -1 guarantees a worst-case clock-to-out delay of 10 ns and supports system clock frequencies up to 100 MHz in typical PCB layouts with proper timing constraints. Actual performance depends on design placement, routing, and I/O loading - verified using Xilinx Foundation or Alliance software timing analysis tools for XC4085XL-1BG560C.

Does XC4085XL-1BG560C require external configuration memory?

Yes, XC4085XL-1BG560C uses volatile SRAM configuration cells and must be reloaded at power-up from an external serial PROM or microprocessor-controlled source. The XC4085XL-1BG560C supports master serial, slave serial, and boundary-scan configuration modes, with PROGRAM_, INIT_, and DONE pins managing the process.

Is XC4085XL-1BG560C pin-compatible with other XC4000XL devices?

XC4085XL-1BG560C shares the BG560 package footprint and I/O bank structure with other XC4000XL family members like XC4062XLA-1BG560C and XC40100XL-1BG560C, but logic resource count and internal routing differ. Pin compatibility is limited to same-package variants; voltage and timing behavior must be validated per design for XC4085XL-1BG560C.

What JTAG features does XC4085XL-1BG560C support?

XC4085XL-1BG560C fully complies with IEEE 1149.1, providing TCK, TMS, TDI, and TDO pins for boundary-scan testing, in-system programming, and debug visibility. It supports instruction register access, device ID readback, and BSDL file-based test vector generation specific to XC4085XL-1BG560C.

Can XC4085XL-1BG560C operate with mixed I/O voltages?

No, XC4085XL-1BG560C supports only 3.3V I/O operation across all banks - it lacks multi-voltage I/O capability. Each I/O bank must be powered at 3.3V (VCCO), and interfacing with 5V or 1.8V peripherals requires level-shifting circuitry external to XC4085XL-1BG560C.
