NOTES FOR DS80C320 DC ELECTRICAL CHARACTERISTICS
All parameters apply to both commercial and industrial temperature operation unless otherwise noted. Specifications to -40°C
are guaranteed by design and are not production tested.
1. All voltages are referenced to ground.
2. Active current is measured with a 25MHz clock source driving XTAL1, V
3. Idle mode current is measured with a 25MHz clock source driving XTAL1, V
4.
5. When addressing external memory. This specification only applies to the first clock cycle following transition.
6. RST = V
7. During a 0-to-1 transition, a one-shot drives the ports hard for two clock cycles. This measurement reflects port
8. Ports 1 and 3 source transition current when being pulled down externally. It reaches its maximum at
9. 0.45<V
10. Over the industrial temperature range, this specification has a maximum value of 200A.

corresponding port latch bit is set to 1. This is only the current required to hold the low level; transitions from 1
to 0 on an I/O pin will also have to overcome the transition current.
Device operating range is 4.5V to 5.5V; however, device is tested to 4.0V to ensure proper operation at
