AMD XC3195-5PC84C

Overview

XC3195-5PC84C from Xilinx is a high-density, static CMOS Field Programmable Gate Array (FPGA) with 7,500 usable logic gates, 484 Configurable Logic Blocks (CLBs) in a 22 × 22 array, and 176 user I/Os. It supports system clock speeds over 85 MHz, features guaranteed flip-flop toggle rates up to 370 MHz, and delivers logic delays as low as 1.5 ns - enabling replacement of TTL/MSI logic and integration of complete subsystems in industrial control and communications interface designs.

For engineers reviewing the XC3195-5PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5V operation, -5 speed grade (1.5 ns logic delay), 84-pin plastic leaded chip carrier (PLCC) package, Soft Startup slew-rate limiting, and full bitstream compatibility with XC3000A/XC3100A families.

Technical Context

The XC3195-5PC84C implements a regular, extendable architecture comprising a perimeter of programmable I/O Blocks (IOBs), a core array of 484 CLBs, and hierarchical interconnect resources including general-purpose metal grids, direct CLB-to-CLB paths, and horizontal longlines. Its configuration memory uses static CMOS cells with dual-inverter latches for high noise immunity and radiation tolerance.

Each IOB supports TTL/CMOS input thresholds, programmable slew rate, passive pull-up, registered/direct I/O, and 3-state control; each CLB contains five logic inputs (A–E), dual flip-flops with shared asynchronous reset (RD) and enable clock (EC), and a 32×1 look-up table supporting two 4-variable functions or one 5-variable function. Configuration is loaded serially or in byte-parallel mode via external PROM or host controller.

Key Specifications

Pinout & Package

XC3195-5PC84C is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-lead geometry, 0.050" lead pitch, and 1.17" × 1.17" body size. The package supports surface-mount assembly and offers thermal and mechanical reliability for industrial temperature range operation (0°C to 70°C).

Equivalent & Alternatives

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

Compared with XC3195-5PC84C, the –6 variant trades 0.2 ns logic delay for reduced cost and power, while XC3195A-5PC84C reflects updated family naming but delivers identical electrical and timing behavior - making it a documentation-aligned drop-in option rather than a technical alternative.

Availability

XC3195-5PC84C is available at Aetrix Electronics and suitable for industrial motion control, legacy bus interface adaptation, digital video timing generation, and telecom line card control requiring stable component supply across extended product lifecycles.

Supply support for XC3195-5PC84C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Xilinx, Inc. pioneered commercial FPGA technology and developed the XC3000 series as the industry's first widely adopted field-programmable logic platform for high-density digital system integration.

The XC3100A family - including XC3195-5PC84C - was designed to deliver ultra-high-speed performance (370 MHz toggle, >85 MHz system clocks) while maintaining full backward compatibility with XC3000A bitstreams and footprints.

FAQ

What is the operating temperature range for XC3195-5PC84C?

The XC3195-5PC84C is specified for commercial temperature operation from 0°C to +70°C. It uses a plastic-leaded chip carrier (PLCC) package rated for this range and does not support extended or industrial temperature grades. Thermal derating is not required within this envelope, and all timing parameters in the datasheet apply strictly within these limits.

Does XC3195-5PC84C support in-system reprogramming?

Yes, XC3195-5PC84C supports in-system reconfiguration via its PROG and CCLK pins. Asserting PROG resets the configuration memory, and reloading the bitstream through serial or parallel mode allows logic changes without removing the device from the board. This capability is enabled by its static CMOS configuration memory architecture and is fully documented in Xilinx Application Note XAPP017.

Is XC3195-5PC84C pin-compatible with XC3064-5PC84C?

No, XC3195-5PC84C is not pin-compatible with XC3064-5PC84C. Although both use the 84-pin PLCC package, XC3195-5PC84C has 176 user I/Os versus 120 for XC3064-5PC84C, resulting in different I/O pin assignments and internal routing resource allocation. Pinouts differ significantly - confirmed by Xilinx Package Pinout Guide DS031, Table 7-1.

What configuration modes does XC3195-5PC84C support?

XC3195-5PC84C supports five configuration modes: Master Serial, Slave Serial, Master SelectMAP, Slave SelectMAP, and Boundary Scan. These are selected via MODE pins (M0–M2). Master Serial uses internal oscillator to clock CCLK; Slave modes accept external clock. All modes load the same 94,984-bit configuration stream, ensuring functional consistency across implementations.

Can XC3195-5PC84C drive 5V TTL loads directly?

Yes, XC3195-5PC84C can directly drive standard 5V TTL loads. Its I/O buffers provide 8 mA sink and 8 mA source current per pin, meeting TTL input current requirements (I_IL ≤ –1.6 mA, I_IH ≤ 40 µA) with margin. Output voltage levels (V_OH ≥ 2.4 V, V_OL ≤ 0.4 V) comply with TTL specifications at V_CC = 5.0 V, eliminating need for external level-shifting circuitry.
