Notes to Tables 46 – 51:

(1)

Timing will vary by I/O pin placement. Therefore, use the Quartus II software to determine exact I/O timing for

each pin.

(2)

This parameter is measured with the Increase tZX Delay to Output Pin option set to Off.

(3)

This parameter is measured with the Increase tZX Delay to Output Pin option set to On.

Power

Consumption

Detailed power consumption information for Mercury devices will be

released when available.

Configuration &

Operation

The Mercury architecture supports several configuration schemes. This

section summarizes the device operating modes and available device

configuration schemes.

Operating Modes

The Mercury architecture uses SRAM configuration elements that require

configuration data to be loaded each time the circuit powers up. The

process of physically loading the SRAM data into the device is called

configuration. During initialization, which occurs immediately after

configuration, the device resets registers, enables I/O pins, and begins to

operate as a logic device. The I/O pins are tri-stated during power-up and

before and during configuration. Together, the configuration and

initialization processes are called command mode; normal device

operation is called user mode.
