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.
