The difference between STC15F104E and STC15F104W:
1. The external interrupt of STC15F104E is not easy to use, the external interrupt of STC15F104W can be used, and there is one more dedicated timer for wake-up after power failure.
2. The timers of STC15F104E have T0 and T1, while the timers of STC15F104W are T0 and T2.
3. The pins are different.
STC15F104W highlights:
(1) Timer module: T0 and T2. When T0 works in mode 0, it is a 16-bit timer counter that can automatically reload the initial value, when mode 2 is an 8-bit counter that automatically reloads, and mode 3 is decomposable; The working mode of T2 is fixed at the 16-bit auto-reloading initial value mode, so it is especially suitable for the LED industry. The timer module of this chip can produce more precise timing time.
(2) Kernel: It adopts Y5 ultra-high-speed CPU kernel, which is 20% faster than ordinary 1T. See the instruction set for details. A total of 111 instructions.
(3) Pin diagram:
P3.3 is RSTOUT_LOW, it outputs low level after power-on and reset. It can also be set to low or high level by software. This pin can be used as the reset circuit of 16-bit or 32-bit single-chip microcomputer; P3.4 can output the system clock, Therefore, it can be used as the clock circuit of 16-bit or 32-bit single-chip microcomputer; the chip also has a strong encryption function, which can replace the encryption chip, and the unit price is only one piece, so it can be recommended to customers.
STC15F104W has no serial port, and has a 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 achieve 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.
The detailed description is as follows:
1 All IO ports are all led out
2 Onboard a single-chip controlled LED, connected to IO port P3.2, can be used for IO port output, PWM wave modulation and other experiments
3 Onboard a patch switch, connected to IO port P3.3, can be used for IO port input, interrupt and other experiments
4 The patch switch and LED external to the IO port do not affect the normal use of the IO port
5 Onboard TTL level serial port, RXD (connected to P3.0) and TXD (connected to P3.1) can be used for STC download program/serial port upper and lower computer communication (requires timer cooperation) and IO port input and output experiments
