P89V52X2
80C51 with 256 B RAM, 192 B data EEPROM
6.2 Memory organization
The various P89V52X2 memory spaces are as follows:
DATA
128 B of internal data memory space (00H:7FH) accessed via direct or indirect
addressing, using instructions other than MOVX and MOVC. All or part of the Stack
may be in this area.
IDATA
Indirect Data. 256 B of internal data memory space (00H:FFH) accessed via indirect
addressing using instructions other than MOVX and MOVC. All or part of the Stack
may be in this area. This area includes the DATA area and the 128 B immediately
above it.
SFR
Special Function Registers. Selected CPU registers and peripheral control and status
registers, accessible only via direct addressing.
CODE
64 kB of Code memory space, accessed as part of program execution and via the
MOVC instruction. The P89V52X2 has 8 kB of on-chip Code memory.
6.3 System clock and clock options
6.3.1 Clock input options and recommended capacitor values for the oscillator
Shown in Figure 5 and Figure 6 are the input and output of an internal inverting amplier
(XTAL1, XTAL2), which can be congured for use as an on-chip oscillator.
When driving the device from an external clock source, XTAL2 should be left disconnected
and XTAL1 should be driven. Power consumption can be further reduced by programming
the EXTCLK bit (UCFG.0).
At start-up, the external oscillator may encounter a higher capacitive load at XTAL1 due to
interaction between the amplier and its feedback capacitance. However, the capacitance
will not exceed 15 pF once the external signal meets the VIL and VIH specications.
Resonator manufacturer, supply voltage, and other factors may cause circuit performance
to differ from one application to another. C1 and C2 should be adjusted appropriately for
each design. Table 4 shows the typical values for C1 and C2 vs. resonator type for various
frequencies.
