AMD XC3190-4PP175C

Overview

XC3190-4PP175C from Xilinx is a high-performance, 6,000-gate Field Programmable Gate Array (FPGA) in the XC3100A family, featuring a 16 × 20 Configurable Logic Block (CLB) array, 144 user I/Os, and guaranteed 370 MHz flip-flop toggle rates. It implements synchronous digital logic using static CMOS configuration memory, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation - used in legacy telecom interface logic and industrial control subsystems.

For engineers reviewing the XC3190-4PP175C datasheet, pinout, applications, or equivalent options, key selection criteria include its 175-pin plastic PGA package, -4 speed grade (4.1 ns logic delay), commercial temperature range (0°C to 70°C), and bitstream compatibility with XC3000A/XC3000L families.

Technical Context

The XC3190-4PP175C implements a regular, extendable architecture comprising a perimeter of programmable Input/Output Blocks (IOBs), a core array of 320 Configurable Logic Blocks (CLBs), and hierarchical interconnect resources including general-purpose metal grids, direct CLB-to-CLB paths, and horizontal longlines. Each CLB contains dual 4-input LUTs, two edge-triggered D flip-flops, programmable clock polarity, and shared asynchronous reset (RD) and enable clock (EC).

Configuration is loaded via serial or parallel mode into distributed static memory cells; the device supports automatic power-up initialization using external PROMs (e.g., XC17XX series). IOBs provide registered/direct I/O paths, slew-rate controlled outputs, programmable pull-ups, and soft-start output activation to suppress ground bounce during initial power-up.

Key Specifications

Pinout & Package

XC3190-4PP175C uses a 175-pin plastic pin-grid array (PPGA) package with 144 user I/Os, 12 dedicated power/ground pins, and 19 configuration/control pins (including INIT, PROGRAM, CCLK, DIN, DONE, and global RESET). Pin numbering follows standard PPGA layout with corner reference markers.

Manufacturer

Xilinx, Inc. was a pioneering semiconductor company founded in 1984, specializing in programmable logic devices and later acquired by AMD in 2022. It developed the first commercial FPGA architecture and established industry standards for reconfigurable computing.

The XC3100A family - including XC3190-4PP175C - was designed for high-speed, high-density custom logic replacement in mission-critical systems where design iteration, NRE avoidance, and deterministic timing were essential.

FAQ

What is the maximum operating frequency of the XC3190-4PP175C?

The XC3190-4PP175C has a guaranteed flip-flop toggle rate of 370 MHz and supports system clock speeds over 85 MHz. Its -4 speed grade specifies a worst-case logic delay of 4.1 ns, enabling reliable operation in synchronous designs with clock periods ≥11.8 ns. Actual achievable frequency depends on routing congestion and logic depth per critical path, but timing analysis tools confirm this limit under worst-case voltage/temperature conditions.

Does the XC3190-4PP175C support in-system reprogramming?

Yes, the XC3190-4PP175C supports in-system reprogramming via its serial configuration interface (DIN/CCLK/DONE/INIT). Configuration can be reloaded dynamically without power cycling, allowing field updates of logic functionality. However, reconfiguration erases current state; retention requires external state storage or use of dual-configuration images with fallback logic - a capability not natively built into the XC3190-4PP175C itself.

Is the XC3190-4PP175C pin-compatible with XC3000-series devices?

Yes, the XC3190-4PP175C is 100% pin-out compatible with XC3000A, XC3000L, XC3100A, and XC3100L families in the same package variant (PP175). This includes identical pin functions for I/O, power, ground, configuration, and clock inputs. No PCB redesign is required when migrating from XC3090A-4PP175C or XC3064A-4PP175C to XC3190-4PP175C, provided the same speed grade and temperature grade are maintained.

What configuration memory technology does the XC3190-4PP175C use?

The XC3190-4PP175C uses internal static CMOS memory cells for configuration storage - not flash or antifuse. These cells retain their state only while powered; configuration must be reloaded at power-up from an external serial PROM (e.g., XC17S100) or microcontroller. The memory cell design includes dual inverters and a pass transistor, providing high noise immunity and zero observed soft errors under alpha radiation testing - critical for industrial and telecom environments.

Can the XC3190-4PP175C operate at 3.3 V?

No, the XC3190-4PP175C is a 5 V-only device requiring VCC = 5.0 V ± 5%. It is not compatible with 3.3 V operation. For 3.3 V applications, Xilinx offered the XC3190L-4PP175C (low-voltage variant), which shares the same logic capacity and pinout but uses different process and I/O threshold circuitry. Mixing XC3190-4PP175C with 3.3 V peripherals requires level-shifting buffers on all I/O lines.
