AMD XC3090-100PQ208C

Overview

XC3090-100PQ208C from Xilinx is a Field Programmable Gate Array (FPGA) with 320 configurable logic blocks (CLBs), 144 user-definable I/Os, and guaranteed 100 MHz maximum flip-flop toggle rate. It implements synchronous digital logic using static CMOS memory cells and supports TTL/CMOS input thresholds in commercial temperature range (0°C to +70°C). It is used in legacy logic replacement and subsystem integration applications.

For engineers reviewing the XC3090-100PQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O count, -100 speed grade timing (e.g., TCKO ≤ 5.0 ns), PQ208 package compatibility, and bitstream compatibility with XC3100 family devices.

Technical Context

The XC3090-100PQ208C implements a two-level hierarchy: configurable logic blocks (CLBs) interconnected via programmable routing resources including horizontal longlines and dedicated clock buffers. Each CLB contains combinational logic (function generators F/G), flip-flops, and enable/reset controls.

It uses static CMOS configuration memory cells for non-volatile logic definition, supports global and local clock distribution paths, and provides programmable input thresholds (TTL or CMOS), slew-rate-controlled outputs, and bidirectional I/O buffers with 3-state control and internal pull-up options.

FAQ

What is the maximum guaranteed toggle frequency for XC3090-100PQ208C?

The XC3090-100PQ208C has a maximum guaranteed flip-flop toggle frequency of 100 MHz, corresponding to a 10 ns minimum clock period. This rating is validated across the commercial temperature range (0°C to +70°C) and 4.75–5.25 V supply, and reflects worst-case timing after place-and-route implementation using XACT tools.

Is XC3090-100PQ208C pin-compatible with XC3090-100PQ208I?

Yes, XC3090-100PQ208C and XC3090-100PQ208I share identical PQ208 packaging, pinout, and logic resources. The only differences are temperature grade (commercial vs. industrial) and supply voltage range (4.75–5.25 V vs. 4.5–5.5 V), making them mechanically and electrically interchangeable in compatible thermal environments.

Does XC3090-100PQ208C support in-system reprogramming?

No, XC3090-100PQ208C uses one-time-programmable (OTP) CMOS configuration memory and requires external PROM or EPROM for configuration on power-up. It does not support in-system programming; reconfiguration necessitates reloading the bitstream from an external source each power cycle.

What is the purpose of the PWRDWN pin on XC3090-100PQ208C?

The PWRDWN pin on XC3090-100PQ208C enables ultra-low-power standby mode. When asserted low, it reduces quiescent supply current to 250 µA (at VCC = 5.25 V, TJ = +85°C), preserving configuration state while minimizing power draw in idle or sleep states of the host system.

How many CLBs and I/Os does XC3090-100PQ208C provide?

XC3090-100PQ208C provides 320 configurable logic blocks (CLBs) and up to 144 user-definable I/Os. These values are fixed for the XC3090 device variant and are independent of speed grade or package; the PQ208 package fully supports all 144 I/Os with no pin limitations.
