PS028702-1210
The products in the Z16FMC Series feature an on-chip oscillator for use with external
crystals with frequencies from 32 kHz to 20 MHz. In addition, the oscillator supports
external RC networks with oscillation frequencies up to 4 MHz or ceramic resonators with
oscillation frequencies up to 20 MHz. This oscillator generates the primary system clock
for the internal CPU and the majority of the on-chip peripherals. Alternatively, the X
input pin also accept a CMOS-level clock input signal (32 kHz to 20 MHz). If an external
clock generator is used, the X

internal clock divider). In RC operation, the system clock is driven by a clock divider
(divide by 2) to ensure 50% duty cycle.
The Z16FMC products support four different oscillator modes:

Figure 58 displays a recommended configuration for connection with an external
fundamental mode, parallel-resonant crystal operating at 20 MHz. Recommended 20 MHz
crystal specifications are provided in Table 164. Resistor R1 is optional and limits total
power dissipation by the crystal. The printed circuit board layout must add no more than 4
pF of stray capacitance to either the X
