Pin Name
I/O
Description
Normal I/O
PA0~PA7
I/O
Bidirectional 8-bit input/output ports.
Schmitt trigger input or CMOS output.
See mask option table for pull-high and wake-up function
PB0~PB7
I/O
Bidirectional 8-bit input/output ports.
Schmitt trigger input or CMOS output.
See mask option table for pull-high function
PE0~PE3
O
or
I/O
Bidirectional 4-bit input/output ports.
Schmitt trigger input and CMOS output.
PE0~PE3 can be per nibble optioned to SEG16~SEG19 by software.
See mask option table for pull-high function
Dialer I/O (See the Dialer I/O function )
HFI
I
Schmitt trigger input structure. An external RC network is recommended for input
debouncing.
This pin is pulled low with internal resistance of 200k
typ.
HFO
O
CMOS output structure.
HDI
I
Schmitt trigger input structure. An external RC network is recommended for input
debouncing.
This pin is pulled high with internal resistance of 200k
typ.
HDO
O
CMOS output structure.
HKS
I
This pin detects the status of the hook-switch and its combination with HFI/HDI can
control the PO pin output to make or break the line.
PO
O
CMOS output structure controlled by HKS and HFI/HDI pins and which determines
whether the dialer connects or disconnects the telephone line.
DNPO
O
NMOS output structure.
XMUTE
O
NMOS output structure. Usually, XMUTE is used to mute the speech circuit when
transmitting the dialer signal.
Peripherals
DTMF
O
This pin outputs dual tone signals to dial out the phone number. The load resistor should
not be less than 5k .
MUSIC
O
This pin outputs the single tone that generated by the PFD generator.
LBIN
I
This pin detects battery low through external R1/R2 to determine threshold voltage.
Absolute Maximum Ratings
Supply Voltage ........................................ 0.3V to 5.5V
Storage Temperature ........................... 50 C to 125 C
Input Voltage .............................. V
SS
0.3 to V
DD
+0.3V
Operating Temperature .......................... 25 C to 70 C
Note: These are stress ratings only. Stresses exceeding the range specified under Absolute Maximum Ratings may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
