STC12C5A60S2 development board

STC12C5A60S2 development board

- The STC12C5A60S2 development board uses the STC12C5A60S2-35I-PDIP40 main control chip. CH30G is used as a USB-to-serial port data download. It uses automatic download. When downloading STC-ISP, there is no need to manually press the reset operation. The crystal oscillator frequency used is 11.0592MHz. Yes, this part of the circuit can be modified according to personal needs and refer to the relevant content of the STC12 series data manual, with a 5V to 3.3V circuit and a power supply port.

- - One point to note, if you are transplanting part of the circuit, please note that the automatic download circuit must not have a filter capacitor with a large value for the target burning chip. When testing other development boards, it was found that if 47uf and 22uf capacitors are used in parallel next to the power supply of the burning target chip, the automatic download will not respond. In other words, it is best to only connect 10uf plus 0.1uf plus 0.01uf in parallel when designing to power the main control chip. You only need to filter out high-frequency signals.
