Description
STC89C52 STC MCU DIP40 Serial Port Programming stc Microcontroller Programmer STC89C52RC IC Support Serial Programming
Product Description
Super anti-interference
1.I/O portThe input/output ports are specially processed, and many interferences are entered from I/0. Each I/0 has protection for the VCC/pair GND diodes.
2. Power supply
The power supply system inside the MCU has been specially processed, and many interferences are from the power supply.
3. Clock
The internal clock circuit of the MCU has been specially processed, and many interferences are entered from the clock part.
4. Watchdog
The watchdog circuit inside the MCU has been specially processed, and cannot be turned off after being turned on, so that the external watchdog can be safely omitted.
5. Reset circuit
The reset circuit inside the MCU has been specially processed, and many interferences are entered from the reset circuit. The STC89C51RC/RD+ series MCU is a high level reset. Recommended external reset circuits are MAX810/STC810, STC6344, STC6345, 813L, 706P; R/C reset, 10uF capacitor/10k resistor, 22uF/8.2k, etc. are also available.
6. Wide voltage, not afraid of power jitter 5V: 6v-3.4v 3V: 4v-1.9v
