Pin Description of HT48C10
Pin Name
I/O
Mask
Option
F unction
PA0~PA7
I/O
Wake-up
Pull-high
or None
Bidirectional 8-bit input/output ports
E ach bit can be configured as a wake-up input by mask option.
Software instructions determine the CMOS output or schmitt
trigger input with or without pull high resistor (by mask option).
PB0~PB7
I/O
Pull-high
or None
Bidirectional 8-bit input/output ports
Software instructions determine the CMOS output or schmitt
trigger input with or without pull high resistor (by mask
option).
VSS
Negative power supply, GND
INT
I
External interrupt schmitt trigger input with pull high resistor
Edge trigger is activated during high to low transition.
TMR
I
Schmitt trigger input for timer/event counter
PC0~PC1
I/O
Pull-high
or None
Bidirectional 2-bit input/output ports
Software instructions determine the CMOS output or schmitt
trigger input with or without pull high resistor (by mask option).
RE S
I
Schmitt trigger reset input, active low
VDD
Positive power supply
OSC1
OSC2
I
O
Crystal or
RC
OSC1 and OSC2 are connected to an RC network or a crystal
(by mask option) for the internal system clock. In the case of RC
operation, OSC2 is the output terminal for 1/4 system clock.
