Table 2.2 Pin Names and Functions (3/3)
Pin Name
No. of pins
(pin. no.)
Input/output or tristate
Function
TPHCKI
(RTS0)
1
(33)
Input
Serial channel 0 enters the TPH mode after a reset and functions to input the transmit
clock to TPH.
Output
Serial channel 0 is the TPH control register and operates as the RTS output pin when set to the
Normal mode.
TPHLAT
(CTS0)
1
(34)
Output
After a reset, serial channel 0 enters the TPH mode and the functions as the latch signal
pin for outputs to TPH.
Input
When set to the Normal mode by the TPH control register, serial channel 0 operates as the
CTS0 input pin.
Consequently, since the CTS0 pin outputs after a reset, use an open drain circuit to connect
the CTS0 pin to CTS0 when serial channel 0 is used in the UART mode.
RTS1
1
(72)
Output
The serial channel 1 RTS1 output pin.
CTS1
1
(73)
Input
The serial channel 1 CTS1 input pin.
SCLK1
1
(74)
Input/output
Functions as the serial channel 1 transceive clock input or output pin. SCLK1 functions as an
input pin after a reset.
TxD1
1
(75)
Output
The serial channel 1 transmit data output pin.
RxD1
1
(76)
Input
The serial channel 1 receive data input pin.
CXIN/CXOUT
2
(1/2)
Input/output
Used to connect the crystal oscillator for the real time clock. A 32.768kHz crystal oscillator
is usually connected.
ALARM
1
(3)
Output
Alarm: The output pin for alarms from the real time clock. Comparator output and either
the 16Hz or 1Hz signal generated by the divider can be output to the ALARM pin using the
alarm select circuit inside the real time clock.
INT0 ~ INT2
3
(4~6)
Input
Interrupt request pins 0 - 2: The input pin used to generate interrupt requests at rise edges.
INT0 is an input pin with a Schmitt circuit.
ALE
1
(35)
Output
Address latch enable signal: AD0 - AD7 addresses are latched on the fall of this signal.
Connected to external memory.
EA
1
(28)
Input
Connect to GND.
CLK
1
(24)
Output
Clock output: Output a clock equal to the oscillation frequency divided by 4. Pulled up
during resets.
RESET
1
(23)
Input
Reset: The reset input pin used to initialize the TMP90C051F. (Built-in pull up register)
X1/X2
2
(26/77)
Input/Output
Used to connect the crystal oscillator that generates the TMP90C051 internal system clock.
V
CC
2
(36/77)
Main power supply pin (+5V)
BAKEN
1
(79)
Input
Backup enable: set BUKEN = 1 when the TMP90C051F main power supply Vcc (pins 36/
77) is +5V.
Set to BUKRN = 0 to provide battery backup for the real time clock when the main power
supply Vcc (pins 36/77) is off.
V
CC (RTC)
1
(78)
The real time clock backup power supply pin. Arrange so that the same power is supplied
to Vcc (RTC) as to Vcc (pins 36/77) when power is being supplied to Vcc (pins 36/77). To
provide battery backup for only the ral time clock, supply + 5V - 2V to Vcc (RTC).
V
SS
(GND)
3
(25/53/80)
GND pin (0V)
