4096 words ✕ 10 bits

8192 words ✕ 10 bits

288 words ✕ 4 bits (including LCD display RAM 29 words ✕ 4 bits)

Six independent I/O ports.

Input is examined by skip decision.

The output structure can be switched by software.

Port D5 is also used as INT pin.

Two independent output ports.

Ports D6 and D7 are also used as XCIN and XCOUT, respectively.

4-bit I/O port; A pull-up function, a key-on wakeup function and output structure can be switched

by software. Ports P00–P03 are also used as SEG21–SEG24, respectively.

4-bit I/O port; A pull-up function, a key-on wakeup function and output structure can be switched

by software. Ports P10–P13 are also used as SEG25–SEG28, respectively.

4-bit I/O port; The output structure can be switched by software. Ports P20–P23 are also used

as SEG17–SEG20, respectively.

1-bit output; Port C is also used as CNTR pin.

8-bit programmable timer with a reload register and has an event counter.

8-bit programmable timer with two reload registers and PWM output function.

16-bit timer, fixed dividing frequency (timer for clock count)

4-bit timer with a reload register (for LCD clock)

16-bit timer (fixed dividing frequency) (for watchdog)
