Altera® Stratix® IV FPGAs deliver a breakthrough level of system bandwidth and power efficiency for high-end applications, allowing you to innovate without
compromise. Stratix IV FPGAs are based on the Taiwan Semiconductor Manufacturing Company (TSMC) 40-nm process technology and surpass all other
high-end FPGAs, with the highest logic density, most transceivers, and lowest power requirements.

■ Up to 1,120 user I/O pins arranged in 24 modular I/O banks that support a wide range of single-ended and differential I/O standards
■ Support for high-speed external memory interfaces including DDR, DDR2, DDR3 SDRAM, RLDRAM II, QDR II, and QDR II+ SRAM on up to 24 modular I/O banks
■ High-speed LVDS I/O support with serializer/deserializer (SERDES), dynamic phase alignment (DPA), and soft-CDR circuitry at data rates up to 1.6 Gbps
■ Support for source-synchronous bus standards, including SGMII, GbE, SPI-4 Phase 2 (POS-PHY Level 4), SFI-4.1, XSBI, UTOPIA IV, NPSI, and CSIX-L1
■ Pinouts for Stratix IV E devices designed to allow migration of designs from Stratix III to Stratix IV E with minimal PCB impact
