Reset signals become inactive typically 200 ms after the

and other ICs is simple. In addition, the RESET pin or a

separate input, MR, can be used as an input for push-button

manual reset capability.

The CAT1021 and CAT1023 provide a precision V_CC

sense circuit and two open drain outputs: one (RESET)

drives high and the other (RESET) drives low whenever

has only a RESET output and does not have a Write

V_CCsense circuit that prevents writes to memory whenever

V_CCfalls below the reset threshold or until V_CCreaches the

reset threshold during power up.
