Product details

Overview

XC3195-3PQ160C from Xilinx is a high-density, high-speed Field Programmable Gate Array (FPGA) with 7,500 usable logic gates, 484 Configurable Logic Blocks (22 × 22 array), and 176 user I/Os in a 160-pin Plastic Quad Flat Package (PQFP). It supports system clock speeds over 85 MHz, features TTL/CMOS input thresholds, on-chip crystal oscillator amplifier, and internal 3-state bus capability - deployed in legacy telecom line cards and industrial control backplanes.

For engineers reviewing the XC3195-3PQ160C datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 370 MHz flip-flop toggle rate, 1.5 ns logic delay, soft-start slew-rate limiting for ground-bounce mitigation, 8 mA output drive, and full bitstream compatibility with XC3000A/XC3100A families.

Technical Context

The XC3195-3PQ160C implements a static CMOS-based FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its 22 × 22 CLB array delivers 1,320 maximum flip-flops and 44 horizontal longlines, supporting high-fan-out signal distribution and low-skew clock nets.

Each IOB provides programmable registered/direct input paths, dual-clock-edge configurable flip-flops, TTL/CMOS threshold selection, and slew-rate-controlled 3-state outputs. Each CLB integrates dual 4-input LUTs (F/G), five logic inputs (A–E), dual flip-flops with shared RD/EC, and programmable clock inversion - enabling single-cycle modulo-8 counters and merged 6–7 variable functions via FGM mode.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Capacity	7,500 usable gates - enables integration of entire subsystems (e.g., protocol engines + interface logic) into one device.
CLB Array Size	22 × 22 = 484 CLBs - provides scalable routing density for complex state machines and datapaths.
User I/O Pins	176 - supports wide parallel buses (e.g., 16-bit data + 24-bit address + control) without external glue logic.
Toggle Rate	370 MHz - guarantees reliable register-to-register timing closure at >85 MHz system clocks.
Logic Delay	1.5 ns - ensures sub-ns path margin for critical timing paths in high-speed control logic.
Output Drive	8 mA sink/source - directly drives 10+ TTL loads or 20+ CMOS inputs without buffers.
Configuration Bits	94,984 bits - defines full functionality including IOB settings, CLB logic, and interconnect routing.

Pinout & Package

XC3195-3PQ160C uses a 160-pin Plastic Quad Flat Package (PQFP) with 40 pins per side, 0.65 mm pitch, and standard JEDEC MO-137AC footprint. Package dimensions are 28.0 × 28.0 × 2.45 mm.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Power Supply	5 V ±5% main supply for core and I/O logic; requires local 0.1 µF decoupling per power pair.
GND	Ground Reference	Dedicated ground pins distributed across all four sides to minimize ground bounce during simultaneous switching.
IOB Pin I	Input Signal Path	Direct or registered input source; configurable for TTL (1.4 V) or CMOS (2.0 V) threshold detection.
IOB Pin O	Output Buffer	CMOS-compatible output with 8 mA drive; slew rate programmable per pin to reduce EMI on non-critical nets.
IOB Pin T	3-State Control	Active-High enable for output buffer; inversion selectable via configuration bit to match bus controller polarity.
CLK1 / CLK2	Global Clock Inputs	Dual edge-programmable clock inputs per die edge; each can drive multiple CLBs and IOBs with low skew.
RESET	Global Asynchronous Reset	Active-Low chip-wide reset that clears all CLB and IOB flip-flops during configuration or runtime fault recovery.
INIT	Configuration Status	Open-drain output indicating configuration success (High) or bitstream error (Low); used for system-level fault logging.

Key Features

Feature	Design Value
Soft Startup	Automatically limits output slew rate at power-up to prevent ground bounce when all 176 I/Os activate simultaneously.
Bitstream Compatibility	Fully compatible with XC3000A, XC3000L, XC3100A, and XC3100L families - enables reuse of verified HDL and place-and-route databases.
On-Chip Oscillator Amplifier	Allows direct connection of external quartz crystal (1–50 MHz) to generate system clock without external oscillator IC.
Error-Checked Configuration	Hardware validates stop bits in bitstream during loading; halts configuration and asserts INIT if corruption detected.
Internal 3-State Bus	Enables bidirectional data transfer across CLB-to-CLB or CLB-to-IOB paths without external transceivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA logic integration applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
XC3195A-3PQ160C	Same gate count, CLB array, and pinout; differs only in speed grade marking ('A' suffix denotes same -3 speed bin).	No functional difference; 'A' suffix reflects identical electrical specs and timing performance.	Select XC3195A-3PQ160C if sourcing from distributors listing the 'A' variant - electrically and mechanically identical to XC3195-3PQ160C.
XC3195-4PQ160C	Same architecture and package but rated for 4 ns logic delay (vs. 1.5 ns), resulting in lower max toggle rate (~250 MHz) and reduced system clock headroom.	Suitable for cost-sensitive designs where 85 MHz system clock is sufficient and tighter timing margins are not required.	Choose XC3195-4PQ160C only if design operates below 60 MHz and requires lower unit cost; avoid for new designs targeting >75 MHz operation.

Compared with XC3195-3PQ160C, the XC3195A-3PQ160C offers identical performance and compatibility, while the XC3195-4PQ160C trades 370 MHz toggle capability for lower cost - making the -3 speed grade essential for designs requiring guaranteed sub-2 ns logic delays and >85 MHz synchronous operation.

FAQ

What is the maximum guaranteed toggle rate for XC3195-3PQ160C?

The XC3195-3PQ160C has a guaranteed flip-flop toggle rate of 370 MHz under specified operating conditions. This value is measured and documented in the official XC3000 Series datasheet (Version 3.1, November 1998) and reflects worst-case performance across voltage, temperature, and process corners. The XC3195-3PQ160C achieves this using its advanced CMOS process and optimized CLB architecture, enabling high-speed register-to-register paths critical for communication protocol engines.

Is XC3195-3PQ160C pin-compatible with other XC3000-series FPGAs?

Yes, XC3195-3PQ160C is 100% pin-out compatible with other XC3000A and XC3100A family members in the PQ160 package, including XC3090A-3PQ160C and XC3164A-3PQ160C. This compatibility extends to physical pad layout, power/ground pin assignments, and I/O bank organization - allowing PCB reuse across density variants. However, CLB count and I/O count differ between devices, so unused pins on lower-density parts remain unconnected.

Does XC3195-3PQ160C support in-system reprogramming?

Yes, XC3195-3PQ160C supports in-system logic changes via serial or parallel configuration modes. Its static memory-based configuration allows full reprogramming without device removal - enabled by external XC17XX series PROMs or microcontroller-driven configuration controllers. The XC3195-3PQ160C retains its programmed logic state indefinitely when powered, and configuration can be reloaded dynamically to implement field-upgradable features or bug fixes.

What is the purpose of the Soft Startup feature in XC3195-3PQ160C?

The Soft Startup feature in XC3195-3PQ160C automatically limits the slew rate of all outputs during initial power-up and configuration completion. This prevents simultaneous switching noise (SSN) and ground bounce that could destabilize power rails or corrupt adjacent signals. After startup, individual I/O slew rates revert to configuration-selected values. This feature is hardware-implemented and requires no user code - it is active in every XC3195-3PQ160C device at power-on.

Can XC3195-3PQ160C operate with a 3.3 V supply?

No, XC3195-3PQ160C is a 5 V-only device and requires a nominal 5.0 V ±5% supply. It belongs to the XC3100A family, which uses standard 5 V CMOS process technology. For 3.3 V operation, Xilinx offers the XC3195L-3PQ160C (low-voltage variant), which shares the same logic capacity and pinout but is optimized for 3.0–3.6 V operation and exhibits reduced speed performance compared to the 5 V XC3195-3PQ160C.
