Note 1: Production tested at +25°C only. Over temperature limits are guaranteed by design, not production tested.
Note 2: WDI, MR and RESET (RESET) open.
Note 3: Threshold voltage is specified for VDD falling.
Note 4: Standard version for tPOR is 200ms (typ). Other option (1.6ms, 25ms, 1600ms) are available by mask option and
upon minimum order quantity. Please contact EM sales.
Note 5: Pulse width must be greater than 1µs to ensure the RESET (RESET) to go active.
Note 6: Standard version for tWD is 1600ms (typ). Other option (6.2ms, 102ms, 25.6s) are available by mask option and
upon minimum order quantity. Please contact EM sales.
