EP2S90F1020C4 Datasheet (PDF) - Altera Corporation
The Stratix® II FPGA family is based on a 1.2-V, 90-nm, all-layer copper
SRAM process and features a new logic structure that maximizes
performance, and enables device densities approaching 180,000
equivalent logic elements (LEs). Stratix II devices offer up to 9 Mbits of
on-chip, TriMatrix™ memory for demanding, memory intensive
applications and has up to 96 DSP blocks with up to 384 (18-bit × 18-bit)
multipliers for efficient implementation of high performance filters and
other DSP functions. Various high-speed external memory interfaces are
supported, including double data rate (DDR) SDRAM and DDR2
SDRAM, RLDRAM II, quad data rate (QDR) II SRAM, and single data
rate (SDR) SDRAM. Stratix II devices support various I/O standards
along with support for 1-gigabit per second (Gbps) source synchronous
signaling with DPA circuitry. Stratix II devices offer a complete clock
management solution with internal clock frequency of up to 550 MHz
and up to 12 phase-locked loops (PLLs). Stratix II devices are also the
industry’s first FPGAs with the ability to decrypt a configuration
bitstream using the Advanced Encryption Standard (AES) algorithm to
protect designs.
