AMD XC3190-3PQ208C

Overview

XC3190-3PQ208C from Xilinx is a high-density, high-speed Field Programmable Gate Array (FPGA) with 6,000 logic gates, 320 Configurable Logic Blocks (CLBs) in a 16 × 20 array, and 144 user I/Os. It features TTL/CMOS input thresholds, on-chip crystal oscillator amplifier, and internal 3-state bus capability - used in digital subsystem integration for industrial control and communications interface logic.

For engineers reviewing the XC3190-3PQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 370 MHz flip-flop toggle rate, 1.55–4.1 ns logic delay range, soft-start slew-rate limiting at power-up, and bitstream compatibility with XC3000A/L and XC3100A/L families.

Technical Context

The XC3190-3PQ208C implements a static-memory-based FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its CLBs contain dual flip-flops with shared asynchronous reset (RD), programmable clock polarity (K), and enable clock (EC), supporting both registered and direct I/O paths.

Interconnect includes general-purpose metal grids, direct CLB-to-CLB routing (e.g., X→B/C, Y→D/A), and horizontal longlines with TBUF access. Configuration supports serial (via XC17XX PROMs) or parallel loading, with automatic bitstream error checking and soft startup that limits output slew rate during initial power-up to suppress ground bounce.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and established foundational architectures for reconfigurable logic design.

The XC3000 Series - including XC3190-3PQ208C - was designed for high-reliability, medium-complexity digital subsystem integration in industrial, aerospace, and instrumentation applications where mask-programmed ASICs were cost-prohibitive.

FAQ

What is the maximum guaranteed flip-flop toggle rate for XC3190-3PQ208C?

The XC3190-3PQ208C has a guaranteed flip-flop toggle rate of up to 370 MHz, verified across commercial temperature range and 5.0 V ±5% supply. This specification reflects worst-case performance under full-load conditions and is documented in the November 1998 XC3000 Series datasheet Version 3.1. The XC3190-3PQ208C achieves this using an advanced CMOS process and optimized CLB clocking architecture.

Does XC3190-3PQ208C support 3.3 V operation?

No, XC3190-3PQ208C is a 5 V device and requires VCC = 5.0 V ±5%. For 3.3 V operation, the pin-compatible XC3190L-3PQ208C variant must be used - it shares the same package and I/O count but operates at 3.0–3.6 V and has reduced speed (190 MHz toggle rate). The XC3190-3PQ208C will not function reliably below 4.5 V.

Is XC3190-3PQ208C pin-compatible with XC3000A family devices?

Yes, XC3190-3PQ208C is 100% pin-out compatible with XC3000A, XC3000L, XC3100A, and XC3100L devices in the same PQ208 package. This includes identical power, ground, I/O, clock, and configuration pin assignments. However, XC3190-3PQ208C requires updated bitstream generation due to enhanced interconnect resources and error-checking logic not present in earlier families.

What configuration methods does XC3190-3PQ208C support?

XC3190-3PQ208C supports five configuration modes: Master Serial (using XC17XX PROM), Slave Serial, Boundary Scan (JTAG), SelectMAP (8-bit parallel), and Fast SelectMAP (8-bit parallel with handshaking). Configuration data is loaded into static memory cells and verified for stop-bit integrity - any error pulls INIT low and halts loading. The XC3190-3PQ208C does not support in-system reprogramming via JTAG alone; external controller or PROM is required.

What is the purpose of Soft Startup in XC3190-3PQ208C?

Soft Startup in XC3190-3PQ208C automatically limits the slew rate of all outputs during initial power-up and configuration completion, preventing simultaneous switching noise and ground bounce. After startup, individual I/O slew rates revert to configuration-programmed settings. This feature is implemented in hardware and requires no user logic - it applies exclusively to the XC3100A/L families and is not present in original XC3000 devices.
