1 . General Overview of STCW0x series MCU. Introduction of STCW0x series MCU (In abundant supply) STCW0x series MCU is a single-chip microcontroller based on a high performance T architecture 0 CPU, which is produced by STC MCU Limited. It is a new generation of 0 MCU of high speed, high stability, wide voltage range, low power consumption and super strong anti-disturbance. Besides, STCW0x series MCU is a MCU of super advanced encryption, because it adopts the ninth generation of STC encryption technology. With the enhanced kernel, STCW0x series MCU is faster than a traditional 0 in executing instructions (about ~ times the rate of a traditional 0 MCU), and has a fully compatible instruction set with traditional 0 series microcontroller. External expensive crystal can be removed by being integrated internal high-precise R/C clock(0.%) with % temperature drift (-0~+) while 0.6% in normal temperature (-0 ~+6) and wide frenquency adjustable between MHz and MHz. External reset curcuit also can be removed by being integrated internal highly reliable one with 6 levels optional threshold voltage of reset. In Keil C development environment, select the Intel 0 to compiling and only contain < reg.h > as header file. STC series MCU with super high-speed CPU core of STC-Y works 0% faster than STC early T series (such as STC/STC/STC0 series) at same clock frequency. Enhanced 0 Central Processing Unit, T, single clock per machine cycle, faster ~ times than the rate of a traditional 0. Operating voltage range:.v ~.V. On-chip K/K/K/K FLASH program memory with flexible ISP/IAP capability, can be repeatedly erased more than 00 thousand times. on-chip bytes SRAM On-chip EEPROM with large capacity can be repeatedly erased more than 00 thousand times. ISP/IAP, In-System-Programming and In-Application-Programming, no need for programmer and emulator. Internal hghly reliable Reset with 6 levels optional threshold voltage of reset, external reset curcuit can be completely removed Internal high- precise R/C clock(0.%) with % temperature drift (-0~+) while 0.6% (-0 ~+6) in normal temperature and wide frenquency adjustable between MHz and MHz (.96MHz /.09MHz /.MHz /.6MHz). No need external crystal and reset, and can output clock and low reset signal from MCU. Operating frequency range: 0- MHz, is equivalent to traditional 0:0~0MHz. UART can be achieved by combining [P.0/INT, P.] with Timer Support the function of Encryption Download (to protect your code from being intercepted). Support the function of RS 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.

2 Resource which can wake up stop/power-down mode are: INT0/P., INT/P. (INT0/INT, may be generated on both rising and falling edges), INT/P., INT/P., INT/P.0 (INT /INT/INT, only be generated on falling edge); pins T0/T(their falling edge can wake up if T0/T have been enabled before power-down mode, but no interrupts can be generatetd); internal low-power special wakeup Timer. Two Timers/Counters----T0(are compatible with Timer0 of traditional 0) and T, T0/T all can independently achieve external programmable clock output 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 V MCU is also not more than.mhz, because the output speed of I/O port of STC series V MCU is not more than.mhz. The speed of external programmable clock output of.v MCU is also not more than MHz, because the output speed of I/O port of STC series.v MCU is not more than MHz. The Programmable clock output of T0 is on P./T0CLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T0/P.) The Programmable clock output of T is on P.0/TCLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T/P.) Two timers/counters in above all can be output by dividing the frequency from to 66. The Programmable clock output of master clock is on P./MCLKO, and its frequency can be divided into MCLK/, MCLK/, MCLK/. 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/P. that the Programmable clock output of master clock of STC series -pin MCU (such as STCW0x series). However, it is on MCLKO/P. that the Programmable clock output of master clock of other STC series MCU including 6-pin or more than 6-pin MCU(such as STCFK60S, STCWKS and so on) One bits Watch-Dog-Timer with -bit pre-scaler (one-time-enabled) advanced instruction set, which is fully compatible with traditional 0 MCU, have hardware multiplication / division command. 6 common I/O ports are available, their mode is quasi_bidirectional/weak pull-up (traditional 0 I/O ports mode) after reset, and can be set to four modes: quasi_bidirectional/weak pull-up, strong push-pull/ strong pull-up, input-only/high-impedance and open drain. the driving ability of each I/O port can be up to 0mA, but the current of the whole chip don t exceed this maximum 90mA. If I/O ports are not enough, it can be extended by connecting a HC9(reference price: RMB 0. yuan). Besides, cascading several chips also can extend to dozens of I/O ports. Package: SOP-, DIP-, DFN-.
