LM63: Questions of LM63CIMA

Jimmy Lai

Part Number: LM63

Dear Team,

Does TI / LM63CIMA could be compatible with SMBUS 3.0? Because We found the SMBUS spec of TI / LM63CIMA is SMBUS 2.0.

Many Thanks,

Jimmy

Hello Jimmy,

The LM63CIMA is not compatible with the SMBus 3.0. The LM63CIMA data out hold time after SMBCLK requires a minimum of 300 ns as shown in page 8 in the datasheet. The SMBus 3.0 has a data hold time of 0 ns. This is shown in page 18 of the datasheet. Please refer to https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1241893/lm63-questions-of-lm63cima .
