It offers watchdog timer
and hardware monitoring functions for reliable operation.
Embedded Linux dependability and watchdog timer
monitoring ensures confidence during surgical procedures.
To ensure reliable operation, the PICO500 also offers watchdog timer
to detect and recover from computer malfunctions; and hardware monitoring for temperature, voltage, fan speed, and more.
For safety-critical applications, the dsPIC33EV devices also include CRC, Deadman Timer (DMT), and Windowed Watchdog Timer
(WWDT) peripherals as well as a backup system oscillator and certified Class B software.
* A built-in watchdog timer
, on-board temperature sensor, and self-diagnostics.
Additional on-board peripherals include a 9-channel, 16-bit timer, a controller for directly driving an LCD display, a temperature sensor, a voltage detection circuit and a watchdog timer
. Integrated connectivity comprises a 5-channel general-purpose serial interface (selectable between UART mode and synchronous mode) and a serial bus interface.
Mohammed Zuhdi Al-Imam, head of the Children Medicine Center at IMC, confirmed that the system is equipped with a watchdog timer
card to output an alarm signal in the unlikely event of a problem with the operating system, a function that provides additional security.
The system also features I/O options including two RS-232/485, four USB, and isolated l/Os; HDD and CompactFlash storage cards; and temperature, voltage, and watchdog timer
By embedding CR oscillating, a low voltage detection circuit and watchdog timer
, the microcontrollers successfully reduce required external components, such as an oscillator and reset IC.
The watchdog timer
will reset the microprocessor if it fails to strobe within the preset timeout period.
The ADSPBF534 processors' system peripherals include an integrated CAN 2.0B controller, a Two Wire Interface controller, two UART ports, an SPI port, two serial ports, two external DMA request lines, nine general-purpose 32-bit timers (eight with PWM capability), a real-time clock, a watchdog timer
, 48 general-purpose I/O pins and a Parallel Peripheral Interface.
