NOTES FOR DS80C320 AC 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. AC electrical characteristics assume 50% duty cycle for the oscillator,
oscillator frequency > 16MHz, and are not 100% tested, but are guaranteed by design.
1. All signals rated over operating temperature at 33MHz.
2. All signals characterized with load capacitance of 80pF except Port 0, ALE, PSEN , RD and WR at 100pF.
Note that loading should be approximately equal for valid timing.
3. Interfacing to memory devices with float times (turn off times) over 30ns may cause contention. This will not
damage the parts but will cause an increase in operating current.
4. Specifications assume a 50% duty cycle for the oscillator. Port 2 timing will change with the duty cycle
variations.
5. Address is held in a weak latch until over driven by external memory.
