Description

The RNA52A10T incorporates two reset circuits, one with and one without a delay function, allowing the generation of

separate reset signals for a microprocessor and associated system circuits. The detection voltage of each reset circuit is

determined by the value of an external resistor, and the internal reference voltage is 1.0 V. The CMOS process for the

RNA52A10T means that the device draws only 1.1 μA (typ.). The reset cancellation delay time is set with a high

degree of accuracy by the values of a capacitor and resistor connected with the CD pin. The MR (manual reset) input

pin is provided for the reset circuit with the delay function, and the reset signal is output in response to a high level on

the MR input pin. The MR pin is pulled down by a 2-MΩ internal resistor. Output pins Vo1 and Vo2 are open drain.
