AMD XC5215-6HQ240IO359

Overview

XC5215-6HQ240IO359 from Xilinx is a 5-Volt, SRAM-based field-programmable gate array (FPGA) with 1,936 logic cells, 244 I/O pins, and four dedicated low-skew global clock nets - designed for cost-sensitive embedded control, industrial interface logic, and reconfigurable digital signal routing in legacy 5V systems.

For engineers reviewing the XC5215-6HQ240IO359 datasheet, pinout, applications, or equivalent options, key selection criteria include its VersaRing™ I/O architecture for pin-locking, IEEE 1149.1 boundary scan support on all I/Os, zero flip-flop hold time with programmable input delay, and compatibility with XC4000-series footprints for drop-in migration paths.

Technical Context

The XC5215-6HQ240IO359 implements a VersaBlock™ architecture composed of 484 configurable logic blocks (CLBs), each containing four independent 4-input LUTs and four D-type flip-flops/latches with shared clock, clock enable, and asynchronous clear. Its local interconnect matrix (LIM) provides full intra-CLB connectivity without consuming general routing resources.

Routing uses six hierarchical levels - single-length, double-length, and Longlines - managed through a General Routing Matrix (GRM); each CLB includes four 3-state buffers driving horizontal/vertical Longlines, and dedicated carry logic enables high-speed arithmetic with cascade chaining across adjacent logic cells.

Key Specifications

Manufacturer

Xilinx, Inc. pioneered commercial FPGA technology and developed the XC5200 series to deliver cost-optimized, reprogrammable logic for 5V industrial and embedded systems before the shift to 3.3V and lower.

The XC5200 family - including XC5215-6HQ240IO359 - was engineered for register-rich, SRAM-based programmability with emphasis on I/O flexibility, timing predictability, and seamless migration from gate arrays and earlier FPGA families.

FAQ

What is the maximum operating frequency of XC5215-6HQ240IO359 in typical designs?

The XC5215-6HQ240IO359 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 net utilization - the -6 speed grade specifies worst-case delays for CLB-to-CLB paths and setup/hold times under defined voltage and temperature conditions.

Does XC5215-6HQ240IO359 support in-system programming via JTAG?

Yes, XC5215-6HQ240IO359 includes full IEEE 1149.1 boundary scan circuitry on all I/O pins and supports JTAG-based configuration, verification, and debugging. The TCK, TMS, TDI, and TDO pins enable bitstream loading, readback, and interconnect testing without requiring dedicated programming headers.

Can XC5215-6HQ240IO359 interface directly with 3.3V devices?

XC5215-6HQ240IO359 inputs can accept 3.3V logic levels when configured for TTL thresholds (1.2V switching point), making them compatible with 3.3V CMOS outputs in mixed-voltage systems. However, its outputs swing 0–5V and require level-shifting or open-drain termination to safely drive 3.3V inputs.

What is the purpose of the PROGRAM pin on XC5215-6HQ240IO359?

The PROGRAM pin on XC5215-6HQ240IO359 is a dedicated, single-function active-low input that forces immediate reinitialization of the SRAM configuration memory - clearing all logic states and reloading the bitstream from external PROM or host processor. It does not share functionality with other pins and overrides all other control signals when asserted.

Is XC5215-6HQ240IO359 still in active production or subject to obsolescence?

XC5215-6HQ240IO359 is classified as obsolete or under obsolescence per Xilinx documentation dated November 1998. Aetrix Electronics maintains legacy inventory and provides lifecycle coordination support, including last-time-buy planning, cross-reference assistance, and technical documentation access for ongoing maintenance of installed systems.
