SNIS217C december 2020 – may 2023 TMP139
PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
For I2C read operation, the host controller sends the device address with R/W bit as 0, after a Start or repeated start. This is followed by the 8-bit register address. Once the register address is available to the TMP139, the host issues a Repeated Start and sends the device address with R/W bit as 1. At this point the device shall send the data from the register address incrementally, till the host sends a NACK. If the read operation results in the internal read register address pointer to rollover, then the TMP139 device behavior is not defined.
