Pin Name Signal Name
Input/Output Function
Power
VCCE
Power supply
—
Power supply to external I/O ports (5 V).
supply
VCCI
Power supply
—
Power supply to internal logic (3.3 V).
VDD
RAM power supply
—
Power supply for internal RAM backup (3.3 V).
FVCC
FLASH power supply —
Power supply for internal flash memory (3.3 V).
VSS
Ground
—
Connect all VSS to ground (GND).
Clock
XIN,
Clock
Input
Clock input/output pins. These pins contains a PLL-based
XOUT
Output
frequency multiplier circuit. Apply a clock whose frequency
is 1/4 the operating frequency. (When using 40 MHz CPU
clock, XIN input = 10.0 MHz)
BCLK/WR System clock
Output
This pin outputs a clock whose frequency is twice that of
external input clock. (When using 10 MHz external input
clock, BCLK output = 20 MHz). Use this output when
external operation needs to be synchronized.
OSC-VCC Power supply
—
Power supply for PLL circuit. Connect OSC-VCC to the
power supply rail.
OSC-VSS Ground
—
Connect OSC-VSS to ground.
VCNT
PLL control
Input
This pin controls the PLL circuit. Connect a resistor and
capacitor to it. (For external circuits, refer to Section 18.1.1,
"Example of an Oscillator Circuit.")
Reset
RESET
Reset
Input
This pin resets the internal circuit.
Mode

Address
A11 – A30 Address
Output
The device has 20 address lines (A11-A30) to allow two
Bus
Bus
channels of up to 2 MB of memory space to be added
external to the chip. A31 is not output.
Note: For boot mode, refer to Chapter 6, "Internal Memory."
