Pin description
Pin
Name
Function
Function expect a port function
VCC, VSS
Power source
Apply voltage of 1.8 to 3.6V to VCC, and 0 V to VSS.
VDDR
Power source
Power source pin only for RAM2. When this pin is used, connect an approximately 0.1
F
bypass capacitor across the VSS line and the VDDR line. When not used, connect it to VSS.
CNVSS
Chip operating mode control pin, which is always connected to Vss.
RESET
Reset I/O
An N-channel open-drain I/O pin for a system reset. This pin has a pull-up transistor. When the
watchdog timer, the built-in power-on reset or the voltage drop detection circuit causes the
system to be reset, the RESET pin outputs "L" level.
XIN
Clock input
Input and output pins for main clock generating circuit
Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins.
XOUT
Clock output
P00/KEY0
P07/KEY7
I/O port P0
8-bit I/O port.
I/O direction register allows each pin to be individually
programmed as either input or output.
CMOS compatible input level
CMOS 3-state output structure
Whether the pull-up function/key-on wakeup function
is to be used or not can be determined by program.
Key-input (key-on wake up interrupt
input) pins
P10, P11
I/O port P1
2-bit I/O port having almost the same function as P0.
CMOS compatible input level
The output structure can be switched to N-channel
open-drain or CMOS by software.
Note: RLSS-only pins
P20(LED0)/INT0
P21(LED1)/INT1
P22(LED2)
P27(LED7)
I/O port P2
8-bit I/O port having almost the same function as P0.
CMOS compatible input level
The output structure can be switched to N-channel
open-drain or CMOS by software.
P2 can output a large current for driving LED.
Interrupt input pins
P30
P37
I/O port P3
8-bit I/O port
I/O direction register allows each pin to be individually programmed as either input or output.
CMOS compatible input level
The output structure can be switched to N-channel open-drain or CMOS by software.
P40(LED8),
P41(LED9)
I/O port P4
2-bit I/O port having almost the same function as P0.
CMOS compatible input level
CMOS 3-state output structure
Note: RLSS-only pins
P42/CARR
1-bit I/O port
CMOS compatible input level
CMOS 3-state output structure
Carrier wave output pin for remote-
control transmit
