| Part: | SH3003 |
| Category: | Power Management => Supervisory Circuits => Microprocessor Supervisors |
| Description: | MicroBuddy® Support IC for Microcontrollers
The programmable SH3003 MicroBuddy® (µBuddy®)
provides all mandatory microcontroller support functions:
♦ CPU Supervisor
♦ Clock Management System
♦ Real-Time Support
♦ Auxiliary functions
Three components make a complete system: any
microcontroller, the SH3003, and a bypass capacitor.
This low-cost system would consume very little power and
have clock-frequency accuracy of ± 0.5%. A fourth
component, a 32.768 kHz crystal, raises the clock
frequency accuracy to ± 0.0256% (± 256 ppm).
The SH3003 can operate completely stand-alone, or
under control of the microcontroller. A single-wire
interface handles both bi-directional communications and
the interrupt / wake-up signal from the SH3003. The
SH3003 stores all configuration, calibration, parameters,
and status information in a 36-byte bank of control
registers. On reset, most of these are reloaded with
defaults from the factory-set nonvolatile memory. The
microcontroller can change any settings on the fly. If
some of the settings must remain fixed, a comprehensive
set of write-protect bits is provided for several related
groups of registers (with both permanent write-inhibit and
lock/unlock capabilities). |
