Built-in 32 kHz RC oscillator (default on power)

★ External 32kHz clock source (OSCI)

The BIAS voltage is fixed at 1/4

COM cycle (DUTY) fixed to 1/8

Look at me Q: 361/888/5898

Built-in display RAM 32×8 bits

Buzzer frequency can be configured for 2kHz, 4kHz

★ Power saving mode (enter through off display and off oscillator)

★ Clock base and watchdog share 1 clock source, 8 frequencies can be configured

★ Time base or watchdog overflow signal output pin is /IRQ pin (open leakage)

3/4 line serial interface

★ Software configuration LCD display parameters

★ Two command formats: write command and read/write data

▲ Read/write display data address automatically increases by 1

★ VLCD pin provides LCD driving voltage (< VDD)
