8-bit microcontrollers with 80C51 core
[1]
ALE loading issue: When ALE pin experiences higher loading (>30 pF) during the reset, the microcontroller may accidentally enter into
modes other than normal working mode. The solution is to add a pull-up resistor of 3 k
to 50 k to V
DD, e.g., for ALE pin.
[2]
For 6-clock mode, ALE is emitted at 1
3 of crystal frequency.
RST

I
Reset: While the oscillator is running, a HIGH logic state
on this pin for two machine cycles will reset the device. If
the PSEN pin is driven by a HIGH-to-LOW input transition
while the RST input pin is held HIGH, the device will enter
the external host mode, otherwise the device will enter the
normal operation mode.
EA

I
External Access Enable: EA must be connected to VSS in
order to enable the device to fetch code from the external
program memory. EA must be strapped to VDD for internal
program execution. The EA pin can tolerate a high voltage
of 12 V.

I/O
Address Latch Enable: ALE is the output signal for
latching the low byte of the address during an access to
external memory. This pin is also the programming pulse
input (PROG) for ash programming. Normally the ALE[1]
is emitted at a constant rate of 1
6 the crystal frequency[2]
and can be used for external timing and clocking. One ALE
pulse is skipped during each access to external data
memory. However, if AO is set to ‘1’, ALE is disabled.
