1T 8051, 8K FLASH, 1.2K SRAM, 1.9V - 5.5V, low power consumption, supports simulation, cheap price
I am using the STC8G1K08A-36I-DFN8 one
Note that because it is based on the C51 core, such a chip must be powered on and reset before it can be programmed. However, because STC's new MCUs are all wide voltage and have very wide voltage support, it is necessary to add a diode at the TX of USB-TTL to prevent the TX voltage from supplying power, resulting in failure to program.
