Good day to all. I'm revisiting an old product line with an eye to creating a couple=20 of new versions of the systems. The current product uses a Xicor=20 X5043 supervisor chip with on-board watchdog timer, power supply=20 supervisor and 512 bytes of eeprom. Because the new PICs contain=20 eeprom, I'm looking for a lower cost solution that contains at least=20 a watchdog timer - a power supervisor would be nice but is not=20 essential at this point. I'm currently on the Microchip website and, although I see lots of=20 choices for voltage supervisors, I haven't yet found any parts that=20 contain a watchdog timer. So: I'm looking for suggestions. 1) Is anyone aware of a Microchip supervisor product (other than a=20 PIC or other microcontroller) that contains a watchdog timer? 2) Does anyone have a favorite external watchdog timer that they=20 really like? Doesn't have to be Microchip but should be readily=20 available and inexpensive.
