Additional Details

The UPD75116CW typically operates within a voltage range of 2.7V to 5.5V. It is usually available in surface mount packages such as QFP or SOP. It includes a watchdog timer to prevent system lockups caused by software malfunctions. The 'CW' designation often indicates a specific package type or a particular feature set. This microcontroller also integrates a low-voltage reset (LVR) function to guard against data corruption due to power fluctuations. Development tools like emulators, compilers, and debuggers are generally available from NEC or third-party vendors.
