STC15F104W STC15W204S SCM module system board core board learning board development board
Differences between STC15F104E and STC15F104W:
1. The external interrupt of STC15F104E is not easy to use, the external interrupt of STC15F104W can be used, and a special timer for wake-up after power failure is added.
2. Timers of STC15F104E include T0 and T1, while timers of STC15F104W include T0 and T2.
3. The pins are different.
STC15F104W focuses on:
(1) Timer module: T0 and T2, T0 is a 16 bit timer counter that can automatically reinstall the initial value in mode 0, 8 bit timer in mode 2, and decomposable in mode 3; The working mode of T2 is fixed in the 16 bit automatic reinstallation initial value mode, so it is particularly suitable for the LED industry. The timer module of this chip can generate more accurate timing time.
(2) Core: Y5 super high speed CPU core is adopted, which is 20% faster than ordinary 1T. See instruction set for details. There are 111 instructions in total.
(3) Pin diagram:
P3.3 is RSTOUT_ LOW, output low level after power on and reset, or set low or high level by software. This pin can be used as the reset circuit of 16 bit or 32 bit MCU; P3.4 It can output the system clock, so it can be used as the clock circuit of 16 bit or 32 bit MCU; The chip also has a strong encryption function, which can replace the encryption chip. The unit price is only more than one piece, so it can be recommended to customers.
STC15F104W has no serial port and has relay broadcast mode. It can simulate I2C, serial port, SPI by software, and use IO port to charge and discharge to measure external voltage to realize AD function.
The input level of P3.1 direct output P3.0 can be set in the download software, similar to the relay broadcast mode of 15 series serial port 1.
Details are as follows:
1 All IO ports are led out
2 On board LED controlled by a single chip microcomputer, connected to IO port P3.2, can be used for IO port output, PWM wave modulation and other experiments
3 On board one way patch switch, connected to IO port P3.3, can be used for IO port input, interrupt and other experiments
4 The external patch switch and LED of the IO port will not affect the normal use of the IO port
5 On board TTL level serial port, RXD (connected to P3.0) and TXD (connected to P3.1) can be used for STC downloading program/serial port communication between upper and lower computers (with the cooperation of timer), IO port input and output and other experiments
