ZXCM209 ZXCM210 VERY LOW POWER MICROPROCESSOR RESET DEVICES DESCRIPTION The ZXCM209/210 are three terminal supervisory circuits used to monitor the power supplies in microprocessor and digital systems. They provide a high performance economical solution when used with 5V, 3V or lower powered circuits. Reset thresholds suitable for operation with a variety of supply voltages are available. These devices provide a reset signal whenever the supply voltage falls below a preset threshold, keeping it asserted for a minimum delay period of 140ms after the supply has risen above the reset level. The ZXCM209 has an active-low RESET output (which is guaranteed to be in the correct state for...
