1. Overview for the Arria II Device Family

The Arria®II device family is designed specifically for ease-of-use. The

cost-optimized, 40-nm device family architecture features a low-power,

programmable logic engine and streamlined transceivers and I/Os. Common

interfaces, such as the Physical Interface for PCI Express®(PIPE) (PCIe®), Ethernet,

and DDR3 memory are easily implemented in your design with the Quartus®II

software, the SOPC Builder design software, and a broad library of hard and soft

intellectual property (IP) solutions from Altera®. The Arria II device family makes

designing for applications requiring transceivers operating at up to 6.375 Gbps fast

and easy.

Notes to Ta ble 1– 1:

(1) The total number of transceivers is divided equally between the left and right side of each device, except for the devices in the F780 package. These devices have eight transceiver channels located only on

the right side of the device.

(2) This is in four multiplier adder mode.

(3) The FPGA fabric can use these phase locked-loops (PLLs) if they are not used by the transceiver.

(4) The number of PLLs depends on the package. Transceiver transmitter (TX) PLL count = (number of transceiver blocks) × 2.

(5) Banks 3C and 8C are dedicated configuration banks and do not have user I/O pins.

(6) For Arria II GZ devices, the user I/Os count from pin-out files includes all general purpose I/O, dedicated clock pins, and dual purpose configuration pins. Transceiver pins and dedicated configuration pins

are not included in the pin count.

(7) For Arria II GZ devices, total pairs of high-speed LVDS SERDES take the lowest channel count of RX/TX.For more information, refer to the High-Speed I/O Interfaces and DPA in Arria II Devices chapter.

(8) The smallest pin package (780-pin package) does not support high-speed LVDS SERDES.

Arria II Device Architecture

Arria II devices include a customer-defined feature set optimized for cost-sensitive

applications and offer a wide range of density, memory, embedded multiplier, I/O,

and packaging options. Arria II devices support external memory interfaces and I/O

protocols required by wireless, wireline, broadcast, computer, storage, and military

markets. They inherit the 8-input ALM, M9K and M144K embedded RAM block, and

high-performance DSP blocks from the Stratix®IV device family with a

cost-optimized I/O cell and a transceiver optimized for 6.375 Gbps speeds.

Figure 1–1 and Figure 1–2 show an overview of the Arria II GX and Arria II GZ device

architecture, respectively.
