AMD XC3190-5PC84C

Overview

XC3190-5PC84C from Xilinx is a high-performance, 6,000-gate Field Programmable Gate Array (FPGA) in a 84-pin plastic leaded chip carrier (PLCC) package, featuring 144 user I/Os, 928 maximum flip-flops, and guaranteed 1.55–4.1 ns logic delays. It implements configurable logic blocks (CLBs), programmable I/O blocks (IOBs), and hierarchical interconnect resources for digital system integration in industrial control and communications subsystems.

For engineers reviewing the XC3190-5PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 ns speed grade, PLCC-84 thermal and mechanical compatibility, 3.3 V nominal supply (XC3190L variant), and bitstream compatibility with XC3000A/XC3100A families for legacy design migration.

Technical Context

The XC3190-5PC84C implements a static memory-based FPGA architecture with a 16 × 20 array of Configurable Logic Blocks (CLBs), each containing dual flip-flops, five-input look-up tables, and programmable clock/enable/reset controls. Its IOBs support TTL or CMOS input thresholds, slew-rate-limited outputs, and soft-start initialization to suppress ground bounce.

Configuration uses external serial PROM (e.g., XC17XX series) or parallel byte-wide loading; configuration memory cells are radiation-hardened static latches with no sense amplifiers, ensuring immunity to alpha particles and power-supply excursions during operation.

The XC3000 Series-including XC3190-5PC84C-was designed for high-density, reprogrammable digital logic integration in systems requiring rapid prototyping, field upgrades, and avoidance of custom ASIC NRE costs.

FAQ

What is the operating temperature range for XC3190-5PC84C?

The XC3190-5PC84C is specified for industrial temperature operation from 0°C to 70°C. This rating is confirmed in the XC3000 Series datasheet Version 3.1, Section 7, and applies specifically to the "C" suffix variant. The device uses plastic encapsulation and is tested across this range for timing, voltage, and functional compliance-making it suitable for factory automation and outdoor telecom cabinets where ambient conditions exceed commercial-grade limits. XC3190-5PC84C maintains full parameter guarantees within this band.

Does XC3190-5PC84C support in-system reprogramming?

Yes, XC3190-5PC84C supports in-system reprogramming via its standard configuration interface. Using the PROG pin (P39), the device can be asynchronously reset and reloaded with a new bitstream from an external serial PROM (e.g., XC1708) or microcontroller-driven parallel port. This capability enables field firmware updates, dynamic function changes, and hardware debugging without physical device replacement-fully leveraging the unlimited reprogrammability feature documented for the XC3100A family. XC3190-5PC84C retains this behavior as a member of that family.

What package type does XC3190-5PC84C use, and is it RoHS-compliant?

XC3190-5PC84C uses an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads and 25.4 mm × 25.4 mm body size. Per historical documentation (Version 3.1, 1998), this package predates RoHS legislation and contains leaded solder and Pb-in-glass frit in the ceramic substrate. It is not RoHS-compliant. For RoHS-constrained designs, engineers must evaluate form-factor alternatives such as modern Xilinx 7-series FPGAs with PLCC-compatible footprints or use conformal coating + legacy procurement pathways. XC3190-5PC84C remains available through authorized distributors with full traceability.

How many configuration memory bits does XC3190-5PC84C require?

XC3190-5PC84C requires exactly 64,160 configuration bits to fully define its logic functionality, interconnect routing, and I/O settings. This value is explicitly listed in the "Product Description" table of the XC3000 Series datasheet (Version 3.1, page 7-3) for the XC3090A/L/3190A/L family row. The bitstream is loaded serially or in byte-parallel mode, and the internal static memory cells retain state indefinitely without refresh. XC3190-5PC84C uses the same configuration architecture as other XC3100A devices, ensuring bitstream compatibility across speed grades and packages.

Is XC3190-5PC84C pin-compatible with XC3090 devices?

Yes, XC3190-5PC84C is pin-compatible with XC3090A, XC3090L, and XC3190L variants in the same PLCC-84 package. All share identical pin functions, electrical characteristics, and mechanical dimensions-as confirmed in the "XC3000 Series Overview" section stating "100% architecture and pin-out compatible with other XC3000 families." This allows drop-in replacement in existing boards designed for XC3090-class devices, provided timing and voltage requirements align. XC3190-5PC84C delivers higher performance (1.55 ns vs. 3.5 ns typical for XC3090A-5) without layout change.
