P89LPC932A1
8-bit microcontroller with accelerated two-clock 80C51 core
7.2 Enhanced CPU
The P89LPC932A1 uses an enhanced 80C51 CPU which runs at six times the speed of
standard 80C51 devices. A machine cycle consists of two CPU clock cycles, and most
instructions execute in one or two machine cycles.
7.3 Clocks
7.3.1 Clock denitions
The P89LPC932A1 device has several internal clocks as dened below:
OSCCLK — Input to the DIVM clock divider. OSCCLK is selected from one of four clock
sources (see Figure 7) and can also be optionally divided to a slower frequency (see
Note: fosc is dened as the OSCCLK frequency.
CCLK — CPU clock; output of the clock divider. There are two CCLK cycles per machine
cycle, and most instructions are executed in one to two machine cycles (two or four CCLK
cycles).
RCCLK — The internal 7.373 MHz RC oscillator output.
PCLK — Clock for the various peripheral devices and is CCLK
2.
7.3.2 CPU clock (OSCCLK)
The P89LPC932A1 provides several user-selectable oscillator options in generating the
CPU clock. This allows optimization for a range of needs from high precision to lowest
possible cost. These options are congured when the ash is programmed and include an
on-chip watchdog oscillator, an on-chip RC oscillator, an oscillator using an external
crystal, or an external clock source. The crystal oscillator can be optimized for low,
medium, or high frequency crystals covering a range from 20 kHz to 18 MHz.
7.3.3 Low speed oscillator option
This option supports an external crystal in the range of 20 kHz to 100 kHz. Ceramic
resonators are also supported in this conguration.
7.3.4 Medium speed oscillator option
This option supports an external crystal in the range of 100 kHz to 4 MHz. Ceramic
resonators are also supported in this conguration.
7.3.5 High speed oscillator option
This option supports an external crystal in the range of 4 MHz to 18 MHz. Ceramic
resonators are also supported in this conguration.
7.3.6 Clock output
The P89LPC932A1 supports a user-selectable clock output function on the
XTAL2/CLKOUT pin when crystal oscillator is not being used. This condition occurs if
another clock source has been selected (on-chip RC oscillator, watchdog oscillator,
external clock input on X1) and if the RTC is not using the crystal oscillator as its clock
source. This allows external devices to synchronize to the P89LPC932A1. This output is
enabled by the ENCLK bit in the TRIM register.
