For more information, see Section 9.3.4, System Power Supply Monitor Design Guidelines. (2) An external resistor divider is required to limit the voltage applied to this device pin. For more information, see Section 9.3.3, USB Design Guidelines. 7.5 Operating Performance Points This section describes the operating conditions of the device. This section also contains the description of each Operating Performance Point (OPP) for processor clocks and device core clocks. Table 7-1 describes the maximum supported frequency per speed grade for the device. Table 7-1. Speed Grade Maximum Frequency DEVICE MAXIMUM FREQUENCY (MHz) SPEED GRADE A53SS R5FSS M4FSS CBASS0 ICSSG DMSC-L DDR4 LPDDR4 AM64x S 1000 800 400 250 333 TBD 800 (DDR-1600)(1) TBD(1) AM64x K 800 400 400 250 250 TBD 800 (DDR-1600)(1) TBD(1) (1) Maximum DDR Frequency will be limited based on the specific memory type (vendor) used in a system and by PCB implementation. 7.6 Power Consumption Summary For information on the device power consumption contact your TI Representative. 7.7 Electrical Characteristics Note The interfaces or signals described in Section 7.7.1 through correspond to the interfaces or signals available in multiplexing mode 0 (Primary Function). All interfaces or signals multiplexed on the balls described in these tables have the same DC electrical characteristics, unless multiplexing involves a PHY and GPIO combination, in which case different DC electrical characteristics are specified for the different multiplexing modes (Functions). 7.7.1 I2C, Open-Drain, and Fail-Safe (I2C OD FS) Electrical Characteristics over recommended operating conditions (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT BALL NAMES in Mode 0: MCU_I2C0_SCL / MCU_I2C0_SDA / I2C0_SCL / I2C0_SDA / EXTINTn BALL NUMBERS: E9, A10, A18, B18, C19 1.8 V MODE VIL Input Low Voltage 0.3 × VDD (1) V VILSS Input Low Voltage Steady State 0.3 × VDD (1) V VIH Input High Voltage 0.7 × VDD (1) TBD V VIHSS Input High Voltage Steady State 0.7 × VDD (1) V VHYS Input Hysteresis Voltage 0.1 × VDD (1) mV IIN Input Leakage Current.
