A system includes a communication bus, a controller device, and a target device. The controller device and the target device may transition between different communication protocols in association with transferring data over the communication bus. The target device may receive a transaction command including a slave address. Based on the slave address, the target device may determine a communication protocol associated with transferring data in association with the transaction command. A first communication protocol may include a message protocol, and the message protocol may be associated with an I2C communication protocol or an I3C communication protocol. The second communication protocol may include a bus protocol, and the bus protocol may be associated with the I2C communication protocol.

Hot transition of I2C to I3C

An Integrated Circuit (IC) includes functional circuitry and attack-protection circuitry (APC). The functional circuitry is to receive a supply voltage from a power-supply input. The APC is coupled to the power-supply input and includes a front-end circuit and an averaging circuit. The front-end circuit is to compare the supply voltage to a plurality of voltage thresholds, and to output a respective plurality of indications that indicate whether the supply voltage violates the respective voltage thresholds. The averaging circuit is to estimate, for a selected subset of the indications, respective duty-cycles at which the indications in the subset exceed the respective voltage thresholds. The APC is to trigger one or more attack detection events in response to the indications and the duty-cycles.
