AMD XC5215-6HQ208 IO359

Overview

XC5215-6HQ208 IO359 from Xilinx is a 5-Volt, SRAM-based Field-Programmable Gate Array with 1,936 logic cells (23,000 equivalent gates), 244 I/O pins, and four dedicated low-skew global clock nets. It implements configurable logic via 4-input LUTs per logic cell, supports IEEE 1149.1 boundary scan on all I/Os, and targets cost-sensitive embedded control and interface bridging applications.

For engineers reviewing the XC5215-6HQ208 IO359 datasheet, pinout, applications, or equivalent options, key selection considerations include its VersaRing™ I/O architecture for pin-locking, zero-flip-flop hold time with programmable input delay, dedicated carry logic for arithmetic, internal 3-state bussing, and footprint compatibility with XC4000-series packages.

Technical Context

The XC5215-6HQ208 IO359 uses a VersaBlock™ architecture composed of 484 Configurable Logic Blocks (CLBs), each containing four independent Logic Cells (LCs) with 4-input LUTs, D-type flip-flops/latches, and dedicated carry multiplexers (CY_MUX). Its local interconnect includes a Local Interconnect Matrix (LIM) and direct connects, enabling high logic utilization without consuming general routing resources.

It features a VersaRing™ I/O interface decoupling IOBs from core logic-IOBs contain no registers but provide programmable slew-rate control, 8-mA drive strength, TTL/CMOS threshold selection, and a one-tap input delay to guarantee zero hold time relative to global clock nets. Boundary scan is implemented per IEEE 1149.1 on all 244 I/O pins.

Key Specifications

Pinout & Package

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and developed the XC5200 family as a cost-optimized, high-I/O-density solution for 5V system integration.

The XC5200 family-including XC5215-6HQ208 IO359-was designed for embedded control, protocol bridging, and interface consolidation in cost-sensitive, high-volume 5V applications where pin flexibility and timing predictability are critical.

FAQ

What is the maximum operating frequency of the XC5215-6HQ208 IO359?

The XC5215-6HQ208 IO359 supports system performance beyond 50 MHz, with benchmarked synchronous clock rates exceeding 66 MHz in optimized designs. Actual achievable frequency depends on logic depth, routing congestion, and clock network usage-designs leveraging dedicated carry logic and global clock nets typically achieve higher sustained throughput.

Does the XC5215-6HQ208 IO359 support 3.3V I/O interfacing?

The XC5215-6HQ208 IO359 is a 5V device with TTL/CMOS input thresholds. Its inputs accept 3.3V logic levels only in TTL mode (1.2V threshold); outputs are 5V-compatible and require level-shifting for reliable 3.3V interface. It does not support mixed-voltage I/O banks or internal 3.3V operation.

How does the VersaRing™ I/O interface benefit PCB design for the XC5215-6HQ208 IO359?

The VersaRing™ I/O interface enables full pin-locking-assigning specific I/O functions to physical pins before logic synthesis. This allows concurrent PCB layout and firmware development, reduces respins due to I/O remapping, and ensures mechanical compatibility with existing XC4000-series footprints in HQ208 packages.

Is IEEE 1149.1 boundary scan available on all I/O pins of the XC5215-6HQ208 IO359?

Yes, the XC5215-6HQ208 IO359 integrates IEEE 1149.1 boundary scan test circuitry on all 244 I/O pins. This provides full visibility into pin states during board-level testing, supports automated fault isolation, and eliminates the need for bed-of-nails fixtures in manufacturing test flows.

What configuration modes does the XC5215-6HQ208 IO359 support?

The XC5215-6HQ208 IO359 supports Express mode and Peripheral Synchronous configuration. It uses the same serial bitstream format as XC4000/Spartan families but differs from XC3000. Configuration is initiated via the dedicated PROGRAM pin, and status is monitored through DONE and INIT pins.
