Overview

This chapter describes the electrical and switching characteristics for Cyclone IV devices. Electrical characteristics include operating conditions and power consumption. Switching characteristics include transceiver specifications, core, and periphery performance. This chapter also describes I/O timing, including programmable I/O element (IOE) delay and programmable output buffer delay. This chapter includes the following sections: ■ “Operating Conditions” on page 1–1 ■ “Power Consumption” on page 1–16 ■ “Switching Characteristics” on page 1–16 ■ “I/O Timing” on page 1–37 ■ “Glossary” on page 1–37

DC Characteristics This section lists the I/O leakage current, pin capacitance, on-chip termination (OCT) tolerance, and bus hold specifications for Cyclone IV devices. Supply Current The device supply current requirement is the minimum current drawn from the power supply pins that can be used as a reference for power size planning. Use the Excel-based early power estimator (EPE) to get the supply current estimates for your design because these currents vary greatly with the resources used.
