Would you recommend a Hi-temp (-55C to 125C) Low-power microcontroller/processor supporting IPMB with redundant IPMB?
Hi,
IPMB? like a I2C protocol?
And for -55C to 125C temperature, the application is Auto?
Thanks!

Hi James,
For high-temp MCU about MSP430, maybe you can check MSP430FR5969-SP:

Thanks!

Thanks. The temp is great. However, it has only 1 I2C bus (P1.6 and P1.7). I need two. Is there other?
Thanks. Actually, I need 2 I2C (for IPMB) + 1 I2C/SPI (for slave devices) + 1 UART (for host interface). That is the minimum. It's preferable 2 buses for slave devices. I looked thru MSP430F selection guide, I found MSP430F249-EP. Its datasheet shows 4 Universal Serial Communication Interfaces (USCI). I'm not sure thou: can this mC be configured to have 4 independent buses: 2 I2C, 1 SPI, 1 UART?
is there other with 5 independent buses: 2 I2C, 2 SPI/I2C, 1 UART?
I went thu selection guide again and found MSP430F5438A-EP. From DS, I'm not sure this has 4 USCI's or 8 USCI's (USCI_A0/1/2/3 plus USCI_B0/1/2/3).
Hi,
For F249-EP, USCIA can used for UART or SPI, USCIB can used for I2C and SPI, thus I think you can use those peripherals as below:
USCIA0 -> UART
USCIA1 -> SPI
USCIB0 -> I2C
USCIB1 -> I2C

For F5438-EP, this device include 4*USCIA + 4*USCIB, more resource you can used:

Thanks!

OK. F5438A data sheet says "up to 4" USCIs, so I was not sure USCIA and USCIB are shared. I have to trace the pin functions. USCIA and USCIB are independent.
