Device Architecture

Revision 4
The third part of the Analog Quad is called the Gate Driver Block, and its output pin is named AG. This
section is used to drive an external FET. There are two modes available: a High Current Drive mode and
a Current Source Control mode. Both negative and positive voltage polarities are available, and in the
current source control mode, four different current levels are available.
The fourth section of the Analog Quad is called the Temperature Monitor Block, and its input pin name is
AT. This block is similar to the Voltage Monitor Block, except that it has an additional function: it can be
used to monitor the temperature of an external diode-connected transistor. It has a modified prescaler
and is limited to positive voltages only.
The Analog Quad can be configured during design time by Libero SoC; however, the ACM can be used
to change the parameters of any of these I/Os during runtime. This type of change is referred to as a
context switch. The Analog Quad is a modular structure that is replicated to generate the analog I/O
resources. Each Fusion device supports between 5 and 10 Analog Quads.
The analog pads are numbered to clearly identify both the type of pad (voltage, current, gate driver, or
temperature pad) and its corresponding Analog Quad (AV0, AC0, AG0, AT0, AV1, …, AC9, AG9, and
AT9). There are three types of input pads (AVx, ACx, and ATx) and one type of analog output pad (AGx).
Since there can be up to 10 Analog Quads on a device, there can be a maximum of 30 analog input pads
and 10 analog output pads.
