St Watchdog Ics Come With Chipenable Capability

摘要

STMicroelectronics has improved its STWD 100 watchdog timer IC by adding a chip-enable input, which prevents automatic reset generation during in-system programming or boot-up, enhancing flexibility for developers to control and manage applications. Comparable alternative devices do not have chip-enable capability. As the first standalone device to join ST's watchdog timer portfolio, the STWD100 is housed in a 5-pin SC70-5 package with a footprint of 2mm × 2.1mm, thereby delivering PCB savings in addition to the extra convenience of the chip enable.
