2.1.6.17.3 MCU Connector

AM62x SKEVM has a 14x2 standard 0.1” spaced MCU connector which includes signals connected to the MCU Domain of SoC. 13 Signals include MCU_I2C0, MCU_UART0 (with flow control), MCU_SPI0 and MCU_MCAN0 signals are connected to the MCU Header. Additional control signals provided on the Header include CONN_MCU_RESETz, CONN_MCU_PORz, MCU_RESETSTATz, MCU_SAFETY_ERRORn, 3.3 V IO and GND. MCU_UART0 signals from AM62x SoC are connected to both MCU Header and FT4232 Bridge through MUX Mfr Part # SN74CB3Q3257PWR. The MCU Header does not include the Board ID memory interface. Allowed current limit is 100 mA on 3.3 V rail.
