• I/O Ports
Input ports:
Selectable as input pull-up resistor/input pull-down resistor/high impedance input.
I/O ports:
Selectable as input pull-up resistor/input pull-down resistor/high impedance input.
Selectable as P-channel open drain output/N-channel open drain output/high-impedance output/
CMOS output.
Can be interfaced with external peripherals that use a different power supply than this device uses.V
DDI is the
power supply pin for ports.
Number of ports:
Input port
: 1 port × 4 bits
Input-output port
: 5 ports × 4 bits
• Melody output
Melody frequency
: 529 Hz to 2979 Hz
Tone length
: 63 varieties
Tempo
: 15 varieties
Melody data
: Stored in program memory
Buzzer driver signal output : 4 kHz
• LCD driver
Number of segments
: 1024 Max. (64 SEG. × 16 COM.)
Duty
: Selectable as 1/1 to 1/16 duty
Bias
: Selectable as 1/4 or 1/5 bias (regulator built-in)
Frame frequency
: ex. 64 Hz (at 1/16 duty), 128 Hz (at 1/8 duty), 256 Hz (at 1/4 duty),
512 Hz (at 1/2 duty), 1024 Hz (at 1/1 duty)
Contrast
: 16 levels adjustable
Display modes
: Selectable as all-ON mode/all-OFF mode/power down mode/
normal display mode
• Multiplier/divider circuit
Multiplier
: (8 bits)
×(8 bits) → Product (16 bits)
Divider
: (16 bits)
/(8 bits) → Quotient (16 bits), Remainder (8 bits)
• System reset function
System reset through RESET pin (selectable as built-in 2 kHz RESET-Sampling circuit by mask option)
System reset by power-on detection (When not using 2 kHz RESET-Sampling circuit)
System reset by low-speed oscillation halt
• Battery check
Low-voltage supply check
The value of the judgment voltage is selected by the software (by setting the LD1 and LD0 bits of BLDCON).
