Functional Description
The SH3001 is a single-chip support system for
microcontrollers, microprocessors, DSPs and ASICs. It
consists of three major functional blocks, each block
having numerous enhancements over alternative
solutions.
The major modules are the Clock Management
System, the Real-Time Support, and the Auxiliary
functions.
The entire chip is controlled by the set of internal
registers and accessed via the single-pin serial interface.
All of the settings, configuration, and calibration or
operating parameters are programmable and re-
programmable at any time. All of the parameters
required for stand-alone operations are initialized on
reset from the built-in factory-programmed Nonvolatile
memory. This allows the SH3001 to operate
autonomously for most of its supervisory functions. The
stand-alone operations do not require the use of the
serial interface or any of the initialization and control
operation, but without these, the full potential benefit of
the SH3001 might not be realized.
In the preferred configuration, where the SH3001 is
tightly coupled to the target micro, the SH3001 offers an
unprecedented level of design flexibility in clock and
power usage management.
The SH3001 is a particularly desirable integration
because the built-in features interact and meld to
produce more useful system level functions.
The SH3001 offers several ways to minimize system
power consumption, such as allowing the target
processor to enter deep sleep by stopping its clock
completely, and to wake up as often as necessary with
no external support. The clock can be programmed to
start up at a given frequency, and software can adjust it
dynamically to manage power consumption and different
operating modes.
Users should consider the interactions of the major
functional blocks to gain the maximum advantage from
the SH3001.
The individual functional blocks are described in the
following sections.
