The AT89C5130A/31A-M clock controller is based on an on-chip oscillator feeding an on-chip
Phase Lock Loop (PLL). All the internal clocks to the peripherals and CPU core are generated
by this controller.
The AT89C5130A/31A-M X1 and X2 pins are the input and the output of a single-stage on-chip
inverter (see Figure 5-1) that can be configured with off-chip components as a Pierce oscillator
(see Figure 5-2). Value of capacitors and crystal characteristics are detailed in the section “DC
Characteristics”.
The X1 pin can also be used as input for an external 48 MHz clock.
The clock controller outputs three different clocks as shown in Figure 5-1:
These clocks are enabled or disabled depending on the power reduction mode as detailed in
Section “Power Management”, page 155.
Two types of clock sources can be used for CPU:
PCON.1
• a clock for the CPU core
• a clock for the peripherals which is used to generate the Timers, PCA, WD, and Port
• a clock for the USB controller
• Crystal oscillator on X1 and X2 pins: Up to 32 MHz (Amplifier Bandwidth)
• External clock on X1 pin: Up to 48MHz
