A Comprehensive Guide to EP4CGX15BF14C8N FPGA - Field Programmable Gate Array

Cyclone® IV GX Field Programmable Gate Array (FPGA) IC 72 552960 14400 169-LBGA

Introduction 

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.

Operating Conditions

When Cyclone IV devices are implemented in a system, they are rated according to a 

set of defined parameters. To maintain the highest possible performance and 

reliability of Cyclone IV devices, you must consider the operating requirements 

described in this chapter. 

Cyclone IV devices are offered in commercial, industrial, extended industrial and, 

automotive grades. Cyclone IV E devices offer –6 (fastest), –7, –8, –8L, and –9L speed 

grades for commercial devices, –8L speed grades for industrial devices, and –7 speed 

grade for extended industrial and automotive devices. Cyclone IV GX devices offer 

–6 (fastest), –7, and –8 speed grades for commercial devices and –7 speed grade for 

industrial devices.
