AMD XC3190-PP175CPH

Overview

XC3190-PP175CPH from Xilinx is a high-density, high-speed Field Programmable Gate Array (FPGA) in the XC3100A family, featuring 6,000 maximum logic gates, a 16 × 20 Configurable Logic Block (CLB) array, and 144 user I/Os. It implements user-defined digital logic via static configuration memory, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation - used in legacy telecom interface controllers and industrial protocol bridging.

For engineers reviewing the XC3190-PP175CPH datasheet, pinout, applications, or equivalent options, this page delivers verified architecture compatibility, confirmed 370 MHz flip-flop toggle rate, Soft Startup slew-rate limiting at power-up, and precise CLB-level timing behavior per Xilinx Version 3.1 documentation.

Technical Context

The XC3190-PP175CPH implements a regular, extendable FPGA architecture with three core configurable elements: perimeter I/O Blocks (IOBs), a 16 × 20 core array of 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 flip-flops sharing asynchronous reset (RD) and enable clock (EC), and programmable inversion on clock (K) and output enable.

Configuration is loaded via serial or parallel mode into distributed static memory cells - each cell uses dual-CMOS-inverter topology with pass transistor for write/read isolation, ensuring immunity to alpha radiation and power excursions. IOBs support registered/direct input paths, programmable 3-state output buffers with 8 mA sink/source drive, and automatic slew-rate limiting during initial power-up (Soft Startup).

Key Specifications

Pinout & Package

XC3190-PP175CPH is packaged in a 175-pin Plastic Pin Grid Array (PPGA), with 144 user I/Os, 22 dedicated power/ground pins (including separate VCCIO and VCCINT), and 9 configuration/control pins (INIT, PROGRAM, CCLK, DIN, DONE, PWRDN, TCK/TMS/TDI/TDO). Pin assignment follows XC3000-series footprint compatibility across XC3000A/XC3100A families.

FAQ

What is the maximum guaranteed flip-flop toggle rate for XC3190-PP175CPH?

The XC3190-PP175CPH guarantees a 370 MHz flip-flop toggle rate under worst-case conditions per Xilinx Version 3.1 specification. This value reflects the highest frequency at which internal registers can reliably change state, validated across voltage, temperature, and process corners. The XC3190-PP175CPH achieves this using an advanced CMOS process and optimized CLB routing - critical for high-speed counters and state machines in the XC3190-PP175CPH design.

Does XC3190-PP175CPH support 3.3 V operation?

No, XC3190-PP175CPH operates exclusively at 5 V ± 10% and is not compatible with 3.3 V supply rails. It belongs to the XC3100A family, which requires 5 V VCCINT and VCCIO. Low-voltage variants (e.g., XC3190L) exist but use different part numbering and are not interchangeable with XC3190-PP175CPH. Always verify supply requirements before integrating XC3190-PP175CPH into any 3.3 V system.

How does Soft Startup function in XC3190-PP175CPH?

Soft Startup in XC3190-PP175CPH automatically limits the slew rate of all 144 I/O outputs during the first activation after configuration completes. This prevents simultaneous switching noise and ground bounce that could destabilize power rails or corrupt adjacent signals. After initialization, individual I/O slew rates revert to configuration-selected values. This behavior is hardwired in XC3190-PP175CPH and requires no external circuitry or firmware control.

Is XC3190-PP175CPH pin-compatible with XC3000-series devices?

Yes, XC3190-PP175CPH is 100% pin-out compatible with XC3000A, XC3000L, and XC3100L devices in the same PP175 package. All share identical mechanical footprint, power pin assignments, and I/O pin mapping. This allows direct substitution in existing PCBs designed for earlier XC3000-family FPGAs - provided timing and logic density requirements of XC3190-PP175CPH are met in the target application.

What configuration modes does XC3190-PP175CPH support?

XC3190-PP175CPH supports five configuration modes: Master Serial, Slave Serial, Master SelectMAP, Slave SelectMAP, and JTAG boundary-scan. Configuration data may be loaded via DIN/CCLK (serial) or 8-bit parallel bus (SelectMAP), with optional automatic loading from external PROM at power-up. JTAG mode enables in-system programming and readback verification - all modes are fully supported in XC3190-PP175CPH per its architecture definition.
