  UART1(RxD/P3.0, TxD/P3.1) can be switched to (RxD_2/P3.6, TxD_2/P3.7),also can be switched to (RxD_3/P1.6, TxD_3/P1.7);
  UART2(RxD2/P1.0, TxD2/P1.1) can be switched to (RxD2_2/P4.6, TxD2_2/P4.7).

• Support the function of Encryption Download (to protect your code from being intercepted).
• Support the function of RS485 Control
• Code protection for flash memory access, excellent noise immunity, very low power consumption
• Power management mode: Slow-Down mode, Idle mode(all interrupt can wake up Idle mode),Stop/Power- Down mode.
• Timers which can wake up stop/power-down mode: have internal low-power special wake-up Timer.
• Resource which can wake up stop/power-down mode are:
  INT0/P3.2, INT1/P3.3 (INT0/INT1, may begenerated on both rising and falling edges),INT2/P3.6, INT3/P3.7, INT4/P3.0 (INT2 /INT3/INT4, only be generated on falling edge);pins CCP0/CCP1/CCP2; pins T0/T1/T2(their falling edge can wake up if T0/T1/T2 have been enabled before power-down mode, but no interrupts can be generatetd);internal low-power special wake-up Timer.
• 6 Timers/Counters:three 16-bit reloadable Timers/Counters (T0/T1/T2, T0 and T1 are compatiblewith Timer0/Timer1 of traditional 8051) T0/T1/T2 all can independently achieve external programmable clock output 3 channels) .3 channels CCP PCA PWM also can be used as three Timers
• Programmable clock output function(output by dividing the frequency of the internal system clock or the input clock of external pin):
  The speed of external programmable clock output of 5V MCU is also not more than 13.5MHz, because the output speed of I/O port of STC15 series 5V MCU is not more than 13.5MHz.
  The speed of external programmable clock output of 3.3V MCU is also not more than 8MHz, because the output speed of I/O port of STC15 series 3.3V MCU is not more than 8MHz.
  ①The Programmable clock output of T0 is on P3.5/T0CLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T0/P3.4)
  ②The Programmable clock output of T1 is on P3.4/T1CLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T1/P3.5)
  ③The Programmable clock output of T2 is on P3.0/T2CLKO (output by dividing the frequency of theinternal system clock or the input clock of external pin T2/P3.1)
  Three timers/counters in above all can be output by dividing the frequency from 1 to 65536.
  ④The Programmable clock output of master clock is on P5.4/MCLKO, and its frequency can be divided into MCLK/1, MCLK/2, MCLK/4.
  The master clock can either be internal R/C clock or the external input clock or the external crystal oscillator.
  MCLK is the frequency of master clock. MCLKO is the output of master clock.
  It is on MCLKO/P3.4 that the Programmable clock output of master clock of STC15 series 8-pin MCU (such as STC15F101W series). However, it is on MCLKO/P5.4 that the Programmable clock output of master clock of other STC15 series MCU including 16-pin or more than 16-pin MCU(such as STC15F2K60S2, STC15W4K32S4 and so on)
