Product details

Overview

XC3090A-7TQ176C from AMD is a Field-Programmable Gate Array (FPGA) featuring 90,000 system gates, 176-pin TQFP package, -7 speed grade (14.3 ns CLB propagation delay), and 5V CMOS I/O compatibility. It serves as a reconfigurable logic fabric for digital control, interface bridging, and custom state-machine implementation in industrial motion controllers.

For engineers reviewing the XC3090A-7TQ176C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count scalability, 5V-tolerant I/O for legacy bus interfacing, CLB timing performance at -7 speed grade, and TQFP thermal and routing constraints in space-constrained PCBs.

Technical Context

The XC3090A-7TQ176C implements a configurable logic block (CLB) architecture with four-input lookup tables (LUTs), dedicated carry logic, and flip-flops with synchronous reset. Each CLB supports combinational and registered logic, enabling efficient implementation of arithmetic functions and finite-state machines.

It uses SRAM-based configuration memory, requiring external PROM or microcontroller-based initialization at power-up. Configuration bitstream loading occurs via JTAG boundary-scan or master serial mode using an external 8-bit PROM, supporting in-system reprogrammability.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Gates	90,000 system gates - defines maximum combinational logic density for custom digital functions
Speed Grade	-7 (14.3 ns CLB t_pd) - guarantees worst-case propagation delay through a single CLB under specified conditions
I/O Voltage	5V CMOS - enables direct interfacing with TTL/5V microcontrollers and legacy parallel buses without level shifters
Package	176-pin Thin Quad Flat Pack (TQFP) - provides 0.5 mm pitch, surface-mount compatibility, and thermal dissipation suitable for industrial ambient
Configuration	SRAM-based, serial/master-serial mode - requires external configuration PROM; supports field updates and design iteration
Operating Temp	0°C to +70°C - rated for commercial temperature range, not extended or industrial grade

Pinout & Package

XC3090A-7TQ176C is housed in a 176-pin Thin Quad Flat Pack (TQFP) with 20×20 mm body size, 0.5 mm lead pitch, and exposed thermal pad (non-electrical). Pinout follows Xilinx XC3000A family standard layout, verified per Xilinx DS003 v2.5 (1995).

Pin/Terminal	Circuit Role	Design Meaning
GND	Ground reference	Multiple dedicated pins provide low-inductance return paths for core and I/O domains
VCC	Core supply	5V supply for internal logic; decoupling required within 1 cm of each VCC pin
VCCO	I/O supply	5V supply for output drivers; separate from VCC to support mixed-voltage I/O (not applicable here)
PROGRAM	Configuration reset	Active-low signal that clears configuration memory and initiates reload sequence
DIN	Serial data input	Accepts configuration bitstream during master-serial programming mode
CLK	Configuration clock	Drives internal shift register during serial bitstream loading
INIT	Initialization status	Open-drain output indicating successful configuration completion or error
IO₀–IO₁₃₁	Configurable I/O	Bi-directional pins supporting input, output, or bidirectional modes with programmable slew rate and pull-up

Key Features

Feature	Design Value
Configurable Logic Blocks (CLBs)	Each CLB contains two 4-input LUTs and two flip-flops, enabling efficient mapping of sequential and combinatorial logic
Carry Chain Logic	Dedicated fast carry path across CLBs supports high-speed arithmetic (e.g., counters, adders) without routing congestion
JTAG Boundary-Scan	IEEE 1149.1-compliant test access port enables in-circuit verification and debugging without physical probes
Master Serial Mode	Supports autonomous configuration from external 8-bit PROM, eliminating need for host processor intervention
5V-Tolerant I/O	All I/O pins accept 5V signals regardless of VCCO setting, simplifying integration with legacy 5V peripherals

FAQ

What is the configuration method supported by XC3090A-7TQ176C?

XC3090A-7TQ176C supports master serial configuration using an external 8-bit PROM and JTAG boundary-scan programming. The device loads its SRAM configuration bitstream on power-up via DIN and CLK pins when PROGRAM is asserted, and INIT indicates completion. No external processor is required for autonomous startup.

Does XC3090A-7TQ176C support 3.3V I/O operation?

No, XC3090A-7TQ176C is specified exclusively for 5V CMOS I/O operation. Its input thresholds and output drive characteristics are designed for 5V logic families. Using it with 3.3V systems requires external level-shifting circuitry to prevent damage or incorrect logic interpretation.

What is the maximum operating frequency achievable with XC3090A-7TQ176C CLBs?

The -7 speed grade of XC3090A-7TQ176C specifies a worst-case CLB propagation delay of 14.3 ns, corresponding to a theoretical maximum toggle frequency of approximately 35 MHz for a single-register-to-register path. Actual system frequency depends on routing delay and logic depth.

Is XC3090A-7TQ176C RoHS compliant?

XC3090A-7TQ176C was manufactured prior to RoHS Directive enforcement and uses leaded solder in its TQFP package. It is not RoHS compliant. For RoHS-compliant alternatives, consider newer Xilinx Spartan or Artix families with equivalent functionality.

Can XC3090A-7TQ176C be reconfigured in-system after power-up?

Yes, XC3090A-7TQ176C supports in-system reconfiguration via JTAG boundary-scan or by asserting PROGRAM to reload the configuration bitstream from the external PROM. This allows field updates without hardware modification, provided the configuration memory remains accessible.
