I/O Descriptions
The device supports 2.7–5.5V supply, and the I/O pins can tolerate VDD +0.5V. However, applying any
voltage beyond power supply in quai-bidirectional mode is not recommended because doing so
causes current to flow from the pin to VDD which consumes extra power.
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. However, Disable-Extern-Boot (See Section , “Security
Lock”) will disable EA#, and program execution is only possible from internal program
memory.
ALE/
PROG#
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 flash programming. Normally the ALE2 is emitted at a constant rate
of 1/6 the crystal frequency3. One ALE pulse is skipped during each access to exter-
nal data memory. However, if AO is set to ‘1’, ALE is disabled.

Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock gen-
erator circuits.

1. I = Input; O = Output
2.ALE loading issue: When ALE pin experiences higher loading (>30pf) during the reset, the MCU may accidentally enter
into modes other than normal working mode. The solution is to add a pull-up resistor of 3-50 K
to V
DD, e.g. for ALE
pin.
3. For 6 clock mode, ALE is emitted at 1/3 of crystal frequency.
