KB3930 Keyboard Controller Datasheet

Analog-to-Digital Converter (ADC)

6 ADC channels with 10-bit resolution.

All ADC pins can be alternatively configured as GPI (general purpose input)

function.

Pulse Width Modulator (PWM)

6 PWM channels are provided. (8-bit *2, 14-bit *2 and FANPWM(12-bit) *2)

Clock source selectable:.

ƒ 1MHz/64KHz/4KHz/256Hz (for 8-bit PWM)

ƒ Peripheral clock or 1MHz (for 14-bit PWM)

ƒ Peripheral clock (for FANPWM)

Duty cycle programmable and cycle time up to 1 sec(for 8-bit PWM)

Watch Dog Timer (WDT)

32.768KHz input clock.

10-bit counter with 32ms unit for watchdog reset.

Three watchdog reset mechanisms.

ƒ Reset 8051 only

ƒ Reset whole chip, except GPIO module.

ƒ Reset whole chip including GPIO module.

Real Time Clock

32.768KHz input clock.

24-bit timer support.

General Purpose Timer (GPT)

Two 16-bit and two 8-bit general purpose timer with 32.768KHz clock source.

General Purpose Wakeup (GPWU)

Those I/O with GPI (general purpose input) configuration can generate

interrupts or wakeup events, except those pins named in GPXIOAxx.
