*Note: preliminary value.
The device’s on-chip oscillator has a high-gain, parallel-resonant amplifier, for connection
to a crystal, ceramic resonator, or any suitable external clock source (XTAL1 = Input,
XTAL2 = Output). The crystal must be AT cut, 1 MHz to 8 MHz maximum, with a series
resistance (RS) less than or equal to 100
suitable external clock source.
The crystal must be connected across XTAL1 and XTAL2 using the recommended capac-
itors from each pin to ground. The typical capacitor value is 10 pF for 8 MHz. Also check
with the crystal supplier for the optimum capacitance.
Zilog’s IR MCU supports crystal, resonator, and oscillator. Most resonators have a
frequency tolerance of less than ±0.5%, which is enough for remote control application.
Resonator has a very fast startup time, which is around few hundred microseconds. Most
crystals have a frequency tolerance of less than 50 ppm (±0.005%). However, crystal
needs longer startup time than the resonator. The large loading capacitance slows down the
oscillation startup time. Zilog
the crystal. If the stray capacitance of the PCB or the crystal is high, the loading
capacitance C1 and C2 must be reduced further to ensure stable oscillation before the

For Stop Mode Recovery operation, bit 5 of SMR register allows you to select the Stop
Mode Recovery delay, which is the T
MCU executes instruction immediately after it wakes up from the STOP mode. If
resonator or crystal is used as a clock source then Stop Mode Recovery delay needs to be
selected (bit 5 of SMR = 1).
