NOTES FOR DS80C323 DC ELECTRICAL CHARACTERISTICS:
All parameters apply to both commercial and industrial temperature operation unless otherwise noted.
Device operating range is 2.7V - 5.5V. DC Electrical specifications are for operation 2.7V - 3.3V.
1. All voltages are referenced to ground.
2. Active mode current is measured with an 18 MHz clock source driving XTAL1, V_CC=RST=3.3V, all
other pins disconnected.
3. Idle mode current is measured with an 18 MHz clock source driving XTAL1, V_CC=3.3V, all other
pins disconnected.
4. Stop mode current measured with XTAL1 and RST grounded, V_CC=3.3V, all other pins disconnected.
