Function
Power
VCCE
Power supply
—
Supplies power (5 V or 3.3V) to external I/O ports.
supply
VCCI
Power supply
—
Supplies power (3.3 V) to the internal logic.
VDD
RAM power supply
—
nternal RAM backup power supply (3.3 V).
FVCC
Flash power supply —
Internal flash memory backup power supply (3.3 V).
VSS
Ground—
Connect all VSS pins to ground
(GND).
Clock
XIN,
Clock
Input
Clock input/output pins. These pins contain a PLL-based
XOUT
Output
frequency multiply-by-4, so input the clock whose frequency is quarter
the operating frequency. (XIN input = 10 MHz when CPU clock operates
at 40 MHz)
BCLK /
System clock
Output
When this signal is System Clock(BCLK), it outputs a clock whose is twice that of
______
WR
external inpout clock. (BCLK output = 20 MHz when CPU clock operates at 40
MHz). Use this clock when circuits are synchronized externally.
______
When this signal is Write(WR), during external write access it indicates the
valid data on the data bus to transfer.
OSC-VCC
Power supply
—
Power supply to the PLL circuit. Connect OSC-VCC to the power supply(3.3V)
OSC-VSS
Ground—
Connect OSC-VSS to ground
.
VCNT
PLL control
Input
This pin controls the PLL circuit. Connect a resistor and capacitor to this pin.
Reset
______
RESET
Reset
Input
This pin resets the internal circuits.
Mode

Address
A12-A30
Address
Output
19 lines of address bus (A12-A30) are provided to accommodate two
bus
channels of 1 MB memory space (max.) connected external to the chip.
A31 is not output.
In the write cycle, of the 16-bit data bus the valid byte positions to write are
_________ ________
________ _______
output as BHW/ BHE and BLW/ BLE. In read cycle, data on the entire 16-bit
data bus is read. However, only the data at the valid byte positions are
transferred to the M32R’s internal circuit.
Data bus
DB0-DB15
Data bus
Input/output
This 16-bit data bus connects to external device.
Note: FP pin should be “H” level in Boot Mode.
