Microcontroller or DSP circuit controls on/off function -
13-Nov-03 Issue of EDN In many applications, a single on/off button
switches the power supply on or off. Usually, the system switches off
regardless of the processing function or workload the microcontroller or DSP
circuit is currently handling. The small circuit in Figure 1 is....[Design

Microcontroller produces analog output - 16-Oct-03 Issue of EDN
A brushless dc motor needs several voltage levels to control its speed
0V to stop the motor, 5V to run it at maximum speed, and some voltages
between these extremes to run it slower. When you use such a motor in a
system under microcontroller supervision,...[Design Idea by Abel Raynus,

Microcontroller programmer taps power from PC’s serial port - 26-Apr-07
Issue of EDN A PC's serial port can supply enough power to supply a
microcontroller programmer....[Design Idea by GY Xu, XuMicro, Houston, TX] |

Microcontroller provides low-cost analog-to-digital conversion, drives seven segment
displays - 10-May-07 Issue of EDN Versatile conversion circuit detects
and displays signal's peak value....[Design Idea by Name withheld by author’s request] |

Microcontroller provides SRAM battery backup - 26-Jun-03 Issue of EDN
To maintain content in the event of power loss, many designs that include SRAM require
a dedicated device that can automatically switch from a standard power supply to
battery operation. Microcontrollers seldom find use in power-switching applications.
Because microcontrollers typically operate from the primary power supply, they stop
execution if that supply drops, thereby making it impossible....[Design Idea by Dave
Bordui, Cypress Semiconductor, Orlando, FL] |
