AMD XC3090A-7PQ160C

Overview

XC3090A-7PQ160C from AMD is a Field-Programmable Gate Array (FPGA) featuring 90,000 system gates, 160-pin Plastic Quad Flat Package (PQFP), -7 speed grade (15 ns CLB propagation delay), and commercial temperature range (0°C to 70°C). It implements configurable logic blocks, I/O blocks, and interconnect resources for digital system prototyping and glue logic replacement in industrial control and communications equipment.

For engineers reviewing the XC3090A-7PQ160C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (118 user I/Os), speed grade timing, PQFP thermal and mounting constraints, and legacy Xilinx 3000A family compatibility.

Technical Context

The XC3090A-7PQ160C belongs to the Xilinx XC3000A FPGA family, built on 0.8 µm CMOS technology with SRAM-based configuration memory. It contains 400 Configurable Logic Blocks (CLBs), each supporting two 3-input lookup tables and flip-flops, and supports up to 118 user-defined I/O pins with TTL/CMOS-compatible voltage levels.

Configuration is performed via serial or parallel mode using external PROM or microprocessor interface. The device requires external power supply sequencing: VCC = 5.0 V ± 5%, and supports boundary-scan testing per IEEE Std 1149.1 (JTAG).

Manufacturer

Xilinx (now part of AMD) pioneered commercial FPGAs and developed the XC3000 series as the first widely adopted SRAM-based programmable logic platform.

The XC3000A family was designed for high-reliability, field-upgradable digital logic replacement in industrial and telecom systems where ASIC NRE costs were prohibitive.

FAQ

What is the configuration method supported by XC3090A-7PQ160C?

The XC3090A-7PQ160C supports master serial, slave serial, and parallel configuration modes. It loads configuration bitstream from external PROM or microprocessor bus, with JTAG boundary-scan used for verification and debug. Configuration occurs on power-up or after PROGRAM pin assertion, and the SRAM cells retain logic mapping until next reconfiguration. XC3090A-7PQ160C does not support active serial or SelectMAP modes introduced in later families.

Does XC3090A-7PQ160C support hot-swapping or live insertion?

No, XC3090A-7PQ160C does not support hot-swapping. Its 5 V supply and TTL-compatible I/O structure require power to be stable before configuration and operation. Inserting or removing XC3090A-7PQ160C while powered risks latch-up, I/O contention, or permanent damage. System-level hot-swap capability must be implemented externally using power sequencers and isolation logic.

What is the maximum operating frequency for CLB logic in XC3090A-7PQ160C?

The XC3090A-7PQ160C -7 speed grade specifies a 15 ns CLB propagation delay (t_PD), translating to a theoretical maximum toggle frequency of approximately 33 MHz for simple register-to-register paths. Actual system clock rates depend on routing delay, fan-out, and logic depth; Xilinx timing reports for XC3090A-7PQ160C typically show 20–25 MHz for fully utilized designs.

Is XC3090A-7PQ160C RoHS compliant?

XC3090A-7PQ160C was manufactured prior to RoHS Directive enforcement and uses leaded solder in its PQFP package. It is not RoHS compliant. No lead-free version was released for the XC3000A family. For RoHS-compliant alternatives, engineers must migrate to newer FPGA families such as Spartan-3 or Artix-7 with verified Pb-free packaging.

Can XC3090A-7PQ160C be reprogrammed in-system without removing it from the PCB?

Yes, XC3090A-7PQ160C supports in-system reprogramming via its serial or parallel configuration interfaces. Using an onboard microcontroller or JTAG controller, the XC3090A-7PQ160C can reload its SRAM configuration bitstream without physical removal. This enables field updates of logic functionality, but requires proper reset coordination and power stability during the PROGRAM cycle.
