Chapter 1: Overview for the Arria II Device Family

Arria II Device Architecture

■ The Quartus® II software allows you to take advantage of MLABs, M9K, and

M144K memory blocks by instantiating memory using a dedicated megafunction

wizard or by inferring memory directly from VHDL or Verilog source code.

Table 1–7 lists the Arria II device memory modes.

DSP Resources

■ Fulfills the DSP requirements of 3G and Long Term Evolution (LTE) wireless

infrastructure applications, video processing applications, and voice processing

applications

■ DSP block input registers efficiently implement shift registers for finite impulse

response (FIR) filter applications

■ The Quartus II software includes megafunctions you can use to control the mode

of operation of the DSP blocks based on user-parameter settings

■ You can directly infer multipliers from the VHDL or Verilog HDL source code

I/O Features

■ Contains up to 20 modular I/O banks

■ All I/O banks support a wide range of single-ended and differential I/O

standards listed in Table 1–8.

Table 1–8. I/O Standards Support for Arria II Devices

Type

I/O Standard

Single-Ended I/O

LVTTL, LVCMOS, SSTL, HSTL, PCIe, and PCI-X

Differential I/O

SSTL, HSTL, LVPECL, LVDS, mini-LVDS, Bus LVDS (BLVDS) (1), and

RSDS

Note to Table 1–8:

(1) BLVDS is only available for Arria II GX devices.

■ Supports programmable bus hold, programmable weak pull-up resistors, and

programmable slew rate control

■ For Arria II devices, calibrates OCT or driver impedance matching for

single-ended I/O standards with one OCT calibration block on the I/O banks

listed in Table 1–9.
