4.5.16.2 MCU Connector

AM62A Low Power SK EVM has a 14 x 2 standard 0.1” spaced MCU connector which includes signals connected to the MCU Domain of the SOC. The connected signals include MCU_I2C0, MCU_UART0 (with flow control), MCU_SPI0 and MCU_MCAN0 signals. Additional control signals connected on the Header includes CONN_MCU_RESETz, CONN_MCU_PORz, MCU_RESETSTATz, MCU_SAFETY_ERRORn, 3.3V IO supply and GND. MCU_UART0 signals from AM62A SOC are connected to both MCU Header and FT4232 Bridge through a MUX Mfr Part # SN74CB3Q3257PWR. The MCU Header does not include the Board ID memory interface. Allowed current limit is 100mA on 3.3V rail.
