FUNCTIONAL DESCRIPTION
True Static Operation
(Am386SXL/SXLV Only)
The Am386SXL/SXLV microprocessor incorporates a
true static design. Unlike dynamic circuit design, the
Am386SXL/SXLV device eliminates the minimum op-
erating frequency restriction. It may be clocked from its
maximum speed all the way down to 0 MHz (DC). Sys-
tem designers can use this feature to design portable
applications with long battery life.
Standby Mode (Am386SXL/SXLV Only)
The true static design of the Am386SXL/SXLV micro-
processor allows for a Standby Mode. At any operating
speed, the microprocessor will retain its state (i.e., the
contents of all its registers). By shutting off the clock
completely, the device enters Standby Mode. Since
power consumption is proportional to clock frequency,
operating power consumption is reduced as the fre-
quency is lowered. In Standby Mode, typical current
draw is reduced to less than 20 microamps at DC. Not
only does this feature save battery life, but it also sim-
plifies the design of power-conscious portable applica-
tions in the following ways.
I
Eliminates the need for software in BIOS to save
and restore the contents of registers.
I
Allows simpler circuitry to control stopping of the
clock since the system does not need to know
the state of the processor.
Lower Operating Icc
(Am386SXL/SXLV Only)
True static design also allows lower operating Icc when
operating at any speed.
Performance on Demand
(Am386SXL/SXLV Only)
The Am386SXL/SXLV microprocessor retains its state
at any speed from 0 MHz (DC) to its maximum operat-
ing speed. With this feature, system designers may
vary the operating speed of the system to extend the
battery life in portable systems.
