Hi everyone. UART to I2C master devices:
NXP SC18IM700 was tested 10 years ago, and found a regulary nice, but poor performing device:
Settings cannot be saved on EEPROM
Undocumented message transaction performance
Weird GPIO messages processing
Under stress, the device can crash
For all these reasons, we turned to BL233
I've dealing with BL233 (
https://i2cchip.com) B and C versions for 10 years. Althrough it's a device with impresive capabilities and afordable price (SO-18 version available!), the company is unresponsive since four mounths ago (please, if someone get in touch, let me know).
After this issue, we turned our eyes (again) to NXP SC18IM704, a modern replacement for SC18IM700.
Nowadays evaluating SC18IM704 (firmware 1.0.2) : the SC18IM700 was far more reliable. Please, take a look at NXP support forums about this device before expend hours (you'll see a pair of post from my own), to figure out. We're expecting a new firmware, released by NXP as requested samples.
Zilog has also this kind of device, but website is offline.
Horter has a I2C modem

Last but not least, you ca relay on a TI MCU with firmware, provided by TI
