Asserting the external RESET input low causes the
device to enter the reset state. The external reset func-
tions as described in the MAXQ7665/MAXQ7666 User’s
Guide . Execution resumes at location 8000h after
RESET is released.
The MAXQ7665A–MAXQ7665D require a crystal with
the following specifications:
Frequency: 8MHz
C
Drive level: 5µW
Series resonance resistance: 30Ω max
Note: Series resonance resistance is the resistance
observed when the resonator is in the series resonant
condition. This is a parameter often stated by quartz crys-
tal vendors and is called R1. When a resonator is used in
the parallel resonant mode with an external load capaci-
tance, as is the case with the MAXQ7665A–MAXQ7665D
oscillator circuit, the effective resistance is sometimes
stated. This effective resistance at the loaded frequency
of oscillation is:

For typical C
