Specification
1
MCU for use
•
RX630-group MCUs in PLQP0144KA-A packages
2
The MCU type name
installed on the debugging
MCU board
•
R5F5630EDDFC
(ROM: 2 Mbytes, RAM: 128 Kbytes, Data flash: 32 Kbytes )
3
Power supply
•
Power (VCC = AVCC0 = VREFH = VCC_USB) at 2.7
*1
to 3.6 V is supplied
from the user system.
•
Power (VREFH0) at 2.7 to AVCC0 is supplied from the user system.
•
Power (VBATT) at 2.3 to 3.6 V is supplied from the user system.
•
The state of power supply can be monitored through the test pins (TP1 for
VREFH0, TP2 for AVCC0, TP3 for VREFH, TP4 for VBATT, TP5 for
VCC_USB, TP6 for VCC, and TP7 for GND).
4
System clock (EXTAL)
•
4 to 16 MHz clock signals are supplied from the user system.
5
Sub clock (XCIN)
•
32.768 kHz clock signals are supplied from the user system.
Note*: 1. Use the debugging MCU board at a voltage (VCC > V
POR
) that doesn't make the MCU enter the state of
power on reset.
