Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MR | input | Manual-reset input: pulling MR low manually resets the device, MR must be held low for at least 1µs to assert RESET, and RESET stays asserted for the reset timeout period after MR is released; MR is internally pulled up to VCC. |
| 2 | SWT | input | Watchdog timeout input: a capacitor from SWT to GND sets tWD = 4.94 x 10^6 x CSWT (seconds, farads), and connecting SWT to GND disables the watchdog timer. |
| 3 | SRT | input | Reset timeout input: a capacitor from SRT to GND sets the reset timeout period tRP = 4.94 x 10^6 x CSRT (seconds, farads), and CSRT must be a low-leakage (< 10nA) capacitor. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | WDS | input | Watchdog select input: connect to GND for normal mode (tWD) or to VCC for extended mode, which multiplies the basic watchdog timeout by 128; a change of state on WDS clears the watchdog timer. |
| 6 | WDI | input | Watchdog input: a falling transition must occur within the selected watchdog timeout period or a reset pulse is issued, falling pulses as short as 300ns clear the timer, and WDI must not be left floating (a 100kΩ resistor to ground is recommended when the watchdog is unused). |
| 7 | RESET | output | Push-pull active-low reset output that asserts when VCC or RESET IN falls below its threshold or MR is pulled low, remains low for the reset timeout period after all reset conditions clear, and then goes high. |
| 8 | VCC | power_in | Supply voltage input (1.2V to 5.5V operating range) that also serves as the input for the fixed-threshold VCC monitor; RESET is guaranteed valid for VCC ≥ 1V. |
