STC15W4K32S4 or
STC15F2K16S2, the same programming tools and methods apply, making the STC15F204EA a versatile option for developers familiar with the STC ecosystem.
What are the key differences between the STC15F204EA and similar models like the STC15W204S or STC15F104W?
The STC15F204EA is part of a broader family of STC15 microcontrollers, including the STC15W204S and STC15F104W. Understanding the differences between these models is essential for selecting the right one for your project.
| Feature | STC15F204EA | STC15W204S | STC15F104W |
| Flash Memory | 4 KB | 4 KB | 4 KB |
| RAM | 256 bytes | 256 bytes | 256 bytes |
| Operating Voltage | 3.0V to 5.5V | 3.0V to 5.5V | 3.0V to 5.5V |
| I/O Pins | 20 pins | 20 pins | 14 pins |
| Programming Interface | ISP | ISP | ISP |
The main differences lie in the number of I/O pins and the package type. The STC15F204EA and STC15W204S are both 20-pin devices, while the STC15F104W is a 14-pin version. If your project requires more I/O functionality, the STC15F204EA is the better choice. For simpler applications, the STC15F104W may suffice.
