AMD XC3190-3PC84C

Overview

XC3190-3PC84C from Xilinx is a high-performance, 6,000-gate Field Programmable Gate Array (FPGA) in the XC3100A family, featuring 320 Configurable Logic Blocks (CLBs) in a 16 × 20 array, 144 user I/Os, and guaranteed 370 MHz flip-flop toggle rates with 1.55–4.1 ns logic delays. It operates at 5 V, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation in digital subsystems.

For engineers reviewing the XC3190-3PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, 8 mA output drive strength, Soft Startup slew-rate limiting, bitstream and footprint compatibility with XC3000A/XC3100A families, and support for automatic serial configuration via XC17XX PROMs.

Technical Context

The XC3190-3PC84C implements a static memory-based FPGA architecture with distributed configuration memory cells controlling CLBs, IOBs, and interconnect resources. Its 320 CLBs each contain dual flip-flops, five-input look-up tables, programmable clock enable, asynchronous reset, and flexible routing to horizontal longlines and direct interconnect paths.

Configuration is loaded via byte-parallel or serial modes using external EEPROM/EPROM/ROM or XC17XX serial PROMs; on-chip initialization logic enables automatic power-up loading. The device supports soft startup - slew-rate limited output activation at power-up - and includes error checking of configuration bitstream to terminate invalid loads.

Key Specifications

Pinout & Package

FAQ

What is the maximum guaranteed toggle rate for XC3190-3PC84C?

The XC3190-3PC84C has a guaranteed flip-flop toggle rate of 370 MHz, verified under worst-case conditions (VCC = 4.5 V, TA = 70 °C). This performance enables system clock speeds exceeding 85 MHz and supports high-speed data path and control logic in applications such as test equipment and medical imaging. The XC3190-3PC84C achieves this using an advanced CMOS process and optimized interconnect architecture.

Does XC3190-3PC84C support 3.3 V operation?

No, XC3190-3PC84C is a 5 V-only device and does not support 3.3 V operation. It requires VCC = 5 V ±10% (4.5–5.5 V) and is incompatible with low-voltage XC3100L family members. For 3.3 V applications, Xilinx offered the pin-compatible XC3190L-3PC84C variant, which trades speed for reduced power and voltage tolerance. The XC3190-3PC84C must be powered from a regulated 5 V rail.

How many configuration bits does XC3190-3PC84C require?

The XC3190-3PC84C requires 64,160 bits of configuration data, stored in internal static memory cells. This bitstream defines CLB logic functions, IOB configurations, and interconnect routing. Configuration can be loaded via byte-parallel mode (using 8-bit data bus) or serial mode (using CCLK/DIN), and is typically stored externally in an XC17XX-series serial PROM or parallel EEPROM. The XC3190-3PC84C validates bitstream integrity during load.

Is XC3190-3PC84C pin-compatible with XC3000A family devices?

Yes, XC3190-3PC84C is 100% pin-out compatible with XC3000A and XC3100A family members in the same package (e.g., PC84C), including identical power, ground, I/O, clock, and configuration pin assignments. This allows drop-in replacement in existing PCB layouts. However, full functional equivalence requires matching speed grade and confirming that the target design fits within the XC3190-3PC84C's 320 CLBs and 144 I/Os.

What packaging options exist for XC3190-3PC84C?

The XC3190-3PC84C is specifically offered in the 84-pin plastic leaded chip carrier (PLCC) package, designated "PC84C" in the part number. While the broader XC3100A family supported over 20 packages - including ceramic PGA, PQFP, and TQFP - the XC3190-3PC84C variant was standardized to the PLCC format for reliability and ease of prototyping. No other package variants (e.g., QFP or BGA) were released for this specific speed-grade and temperature version.
