The OP

Can you tell me the difference between sp3223 and max3223? [Copy link]

I was debugging a design board recently and found a problem when testing the serial port: there was no problem with the max3223 level conversion chip, but when I switched to sp3223, the serial port output garbled characters. The baud rate of UART is 115200bps. Please help me analyze the problem.

To use the current popular online language: Maxim is the "original", the others are "reposted". After Maxim made the 232 interface chip popular, companies that followed suit and made compatible products sprang up like mushrooms after rain, everyone wanted to get involved, and everyone wanted to grab a piece of the pie. The series produced by Sipex starts with SP, the series produced by STMicroelectronics starts with ST. The once arrogant Analog Devices has also lowered its profile. Its ADM series has excellent indicators, but it sells cheaper than Maxim. TI has simply lost all its face and simply calls its compatible ICs MAX... Looking back at the "original" Maxim, it seems that except for the 232 interface IC, it has never produced any other impressive chips.

 MAX3223 is not a product of one company. Both Maxim and TI produce it. The upper limit of the former's speed is 120kbps, while the latter can reach 250kbps. The upper limit of the speed of SP3223 is the same as that of Maxim, which is also 120kbps.

max232, the genuine one costs 7-8 yuan, the counterfeit trend is on the rise again... TI is really shameless, naming it the same as MAX, speechless... Although the functions are similar, there are definitely differences in performance...

I feel like they are all pretty much the same, there isn't much difference.

Thank you for your reminder, it is caused by the baud rate of some chips not being reached.

I have used 9600 as the highest bit rate for 232 communication and have never encountered the same problem.
