AMD XC5215-6HQ208IO359

Overview

XC5215-6HQ208IO359 from Xilinx is a 5-Volt, SRAM-based Field-Programmable Gate Array with 1,936 logic cells (23,000 equivalent gates), 244 user I/Os, and four low-skew global clock nets. It implements synchronous digital logic using configurable CLBs with 4-input LUTs and D-flip-flops/latches, and is used in legacy industrial control, telecom interface, and reconfigurable embedded systems requiring field-upgradable hardware.

For engineers reviewing the XC5215-6HQ208IO359 datasheet, pinout, applications, or equivalent options, key selection criteria include its VersaRing I/O architecture for pin-locking, dedicated carry logic for arithmetic acceleration, IEEE 1149.1 boundary scan support, zero hold-time input delay configuration, and compatibility with Xilinx Foundation design tools targeting PC and workstation platforms.

Technical Context

The XC5215-6HQ208IO359 uses a VersaBlock architecture composed of 484 Configurable Logic Blocks (CLBs), each containing four independent Logic Cells (LCs) with 4-input LUTs, edge-triggered D-flip-flops or transparent latches, and dedicated carry multiplexers. 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-eliminating IOB registers to maximize I/O count-and supports programmable slew-rate control, 8-mA output drive, TTL/CMOS input thresholds, and a one-tap input delay element that guarantees zero flip-flop hold time when using global clock nets.

Key Specifications

Pinout & Package

Manufacturer

Xilinx, Inc. was a pioneering programmable logic company founded in 1984 and acquired by AMD in 2022. It developed industry-standard FPGA architectures and toolchains for digital system design.

The XC5200 Series-including XC5215-6HQ208IO359-was designed for cost-sensitive, high-I/O-density applications in industrial, telecom, and instrumentation markets where reprogrammability and pin-locking accelerated time-to-market.

FAQ

What is the maximum system clock frequency supported by XC5215-6HQ208IO359?

The XC5215-6HQ208IO359 achieves typical system performance beyond 50 MHz, with benchmarked synchronous designs running above 66 MHz. Actual achievable clock speed depends on logic depth, routing congestion, and placement; the -6 speed grade specifies worst-case propagation delays optimized for this performance tier. XC5215-6HQ208IO359 does not guarantee minimum clock period across all configurations, so timing closure must be verified per design using Xilinx Foundation software.

Does XC5215-6HQ208IO359 support in-system programming via JTAG?

Yes, XC5215-6HQ208IO359 includes full IEEE 1149.1 boundary scan circuitry on all I/O pins and supports configuration through the JTAG TAP controller. It enables in-system programming, debugging, and board-level testing without requiring external configuration PROMs. XC5215-6HQ208IO359 uses the same JTAG instruction set and boundary-scan register structure as other XC5200 devices, ensuring interoperability with standard JTAG tools.

Can XC5215-6HQ208IO359 interface directly with 3.3-V logic devices?

XC5215-6HQ208IO359 operates at 5 V and supports TTL input thresholds (1.2 V), allowing reliable reception from 3.3-V CMOS outputs when configured in TTL mode. However, its outputs swing rail-to-rail at 5 V and are not 3.3-V tolerant-direct connection to 3.3-V inputs requires level-shifting circuitry. XC5215-6HQ208IO359 does not include internal voltage translators or mixed-voltage I/O banks.

What configuration modes does XC5215-6HQ208IO359 support?

XC5215-6HQ208IO359 supports Express configuration mode and Peripheral Synchronous mode. Express mode enables faster loading from serial PROMs, while Peripheral Synchronous mode allows parallel configuration using microprocessor-style handshaking. It does not support Power-down mode or internal oscillator-based configuration. XC5215-6HQ208IO359 requires external configuration memory and relies on PROGRAM, INIT, and DONE signals for control sequencing.

Is XC5215-6HQ208IO359 still in production or subject to obsolescence?

XC5215-6HQ208IO359 is marked as obsolete or under obsolescence per Xilinx documentation dated November 1998. No new production lots have been manufactured since the early 2000s. Aetrix Electronics provides traceable, tested inventory with full lifecycle support-including counterfeit mitigation, extended warranty, and engineering consultation-for continued use in legacy system maintenance and repair programs involving XC5215-6HQ208IO359.
