l  3 standard 80C51 timers: Timer0, Timer1 and Timer 2

l  1 channels common cycle, duty cycle adjustable PWM

l  1 UART/SPI/IIC communication interface (SSI)

Analog Peripheral:

l  5-channel dual mode touch circuit with low power consumption can be configured for high sensitivity or high reliability mode:

n  High sensitivity model to adapt to touch keys from a distance, close to the induction of sensitivity to demand higher touch application

n  High reliability model has very strong anti-interference, can pass the test of 10 v dynamic CS

n  Supporting 5-channels touch keys and derivative functions

n  Development software library support high flexibility and low development difficult

n  Automatic debugging software support, intelligent development

n  When scanning with a single TouchKey in stop mode, the overall power consumption of the chip can be as low as 11uA

Power Saving Mode:

l  IDLE Mode: can be woken up by any interrupt.

l  STOP Mode: can be woken up by INT0, INT2, Base Timer and TK.
