AMD XC3190-5PP175C

Overview

XC3190-5PP175C from Xilinx is a high-density Field Programmable Gate Array (FPGA) with 6,000 logic gates, 320 Configurable Logic Blocks (CLBs) in a 16 × 20 array, 144 user I/Os, and guaranteed 190 MHz flip-flop toggle rate. It implements custom digital logic using static memory-based configuration, supports TTL/CMOS input thresholds, and integrates subsystems into a single package for telecom interface logic and industrial control state machines.

For engineers reviewing the XC3190-5PP175C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O count, toggle rate, configuration memory size (64,160 bits), and compatibility with XC3000A/XC3100A bitstreams and pinouts.

Technical Context

The XC3190-5PP175C uses a distributed static memory configuration architecture with perimeter I/O Blocks (IOBs), a core array of CLBs, and programmable interconnect resources including horizontal longlines, general-purpose metal grids, and direct CLB-to-CLB routing paths. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock inversion, and a 32×1 look-up table supporting two 4-variable functions or one 5-variable function.

IOBs provide registered/direct input paths, programmable 3-state output buffers with 8 mA sink/source drive, slew-rate control, soft startup at power-up, and configurable TTL/CMOS input thresholds. Configuration data is loaded serially or in byte-parallel mode, with error checking on stop-bit positions and automatic initialization from external PROMs like XC17XX series.

Key Specifications

Pinout & Package

XC3190-5PP175C is packaged in a 175-pin Plastic Pin Grid Array (PPGA) with 1.27 mm pitch, 27.94 mm × 27.94 mm body size, and 3.56 mm height. The package supports full I/O access on all four sides with dedicated power/ground pins distributed for noise reduction.

FAQ

What is the maximum operating frequency supported by XC3190-5PP175C?

The XC3190-5PP175C guarantees a 190 MHz flip-flop toggle rate and supports system clock speeds over 85 MHz. Its 1.55 ns logic delay and low-skew clock distribution enable reliable operation at these frequencies in properly constrained designs. Timing closure depends on placement, routing, and I/O loading - actual achievable frequency must be verified using Xilinx Foundation or M1 software timing analysis tools with the XC3190-5PP175C speed file.

Is XC3190-5PP175C compatible with modern Xilinx development tools?

XC3190-5PP175C is supported only by legacy Xilinx development tools, including Foundation Series 1.x and M1 software released prior to 2000. It is not supported by ISE, Vivado, or any post-2005 Xilinx toolchain. Users must retain original floppy disk or archived CD-ROM versions of Foundation F1.5 or M1.5 to synthesize, place-and-route, and generate bitstreams for XC3190-5PP175C.

Does XC3190-5PP175C support in-system programming?

XC3190-5PP175C supports in-system configuration via serial or parallel modes using external PROMs (e.g., XC17128), but does not support in-system reprogramming of its internal static configuration memory. Configuration is volatile - the device must reload its bitstream from external memory at each power-up. True in-system programmability (ISP) requires external JTAG or microcontroller-controlled PROM reload, not native device capability.

What is the configuration memory technology used in XC3190-5PP175C?

XC3190-5PP175C uses static CMOS memory cells for configuration storage - each cell consists of two cross-coupled inverters and a pass transistor. This design provides high noise immunity and radiation tolerance, with no observed soft errors under alpha particle exposure. Unlike SRAM-based FPGAs, these cells retain state indefinitely when powered but require external non-volatile storage (PROM/EEPROM) for persistent configuration.

Can XC3190-5PP175C operate at 3.3 V?

No, XC3190-5PP175C is a 5 V-only device specified for 4.5 V to 5.5 V operation. It belongs to the XC3100A family, which does not include low-voltage variants. For 3.3 V operation, designers must select XC3190L-series parts (e.g., XC3190L-5PQ208C), which are architecturally identical but rated for 3.0–3.6 V supply and exhibit reduced speed performance.
