Input
AVSS
I Power supply input pins to A/D converter.
Connect AVCC to VCC. Apply 0V to AVSS.
Connect a capacitor between AVCC and AVSS.
Reset Input
RESET
I Input ā€œLā€ on this pin resets the MCU
MODE
MODE
I Connect this pin to VCC via a resistor
Main Clock Input
Main Clock Output
XIN
XOUT
I These pins are provided for the main clock
O generation circuit I/O. Connect a ceramic
resonator or a crystal oscillator between the XIN
and XOUT pins. To use an externally derived
clock, input it to the XIN pin and leave the XOUT
pin open.

CNTR0
O Timer X output pin.
Timer Z
TZOUT
O Timer Z output pin
Timer C
TCIN
I Timer C input pin
CMP0_0 to CMP0_2,
CMP1_0 to CMP1_2
O Timer C output pins.
Serial Interface
CLK0
I/O Transfer clock I/O pin.
RXD0
I Serial data input pin.
TXD0
O Serial data output pin.
SSU
SSI
I/O Data I/O pin.
SCS
I/O Chip-select signal I/O pin.
SSCK
I/O Clock I/O pin.
SSO
I/O Data I/O pin.
Reference Voltage
Input
VREF
I Reference voltage input pin to A/D converter
Connect VREF to VCC
A/D Converter
AN8 to AN11
I Analog input pins to A/D converter
I/O Port
P1_0 to P1_7, P3_3
to P3_5, P3_7, P4_5
I/O These are CMOS I/O ports. Each port contains
an I/O select direction register, allowing each pin
in that port to be directed for input or output
individually.
Any port set to input can select whether to use a
pull-up resistor or not by program.
P1_0 to P1_3 also function as LED drive ports.
Input Port
P4_6, P4_7
I Port for input-only

 Overview
This MCU is built using the high-performance silicon gate CMOS process using a R8C/Tiny Series CPU core and is packaged in a 20-pin plastic molded LSSOP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1 Mbyte of address space, it is capable of executing instructions at high speed. Furthermore, the data flash ROM (1KB Ɨ 2blocks) is embedded in the R8C/15 group.
The difference between R8C/14 and R8C/15 groups is only the existence of the data flash ROM. Their peripheral functions are the same.

 Applications
Electric household appliance, office equipment, housing equipment (sensor, security), general industrial equipment, audio, etc.
