The reset pulse period generated by a MR transition is a minimum of 800 ms and a maximum of 2 sec duration. In addition, The MR input signal is blocked for an additional 49S minimum after the reset pulse ends. During the MR disable period, the microcontroller is guaranteed a time period free of additional manual reset signals. During this period DRAM contents can be refreshed or other critical system tasks undertaken. Low power consumption makes the ASM161/162 ideal for use in portable and battery operated equipments. With 3V supplies power consumption is 8W typically and 30W maximum. The ASM161 has an open-drain, active-LOW RESET output and requires an external pull-up resistor. The ASM162 has an active HIGH RESET output.
