I am not familiar with EP devices and I am having trouble following all the power requirements.
What are the required voltage supply rails needed for the AM243x devices?
Peripherals such as UART/SPI/USB2/ICSS will be used.
I don't have clarity on memory yet...is external memory needed? If so what do the voltage rails look like?
Regards,
Darren
Hello Darren,
Our priority is to make sure Sitara MCU EP devices are as easy to use and ramp up on as possible :)
1) Much of this information can be found in the device Datasheet. (https://www.ti.com/lit/gpn/am2431)
Power requirements can be estimated with the AM64x/AM243x Power Estimation Tool (Rev. A)
Required Voltage Rails are boxed in red, optional rails in blue (required if peripheral/functionality is required by system)
Here are some of our Hardware Design Documents:
You can also refer to our EVM docs for TI-approved HW examples:
2) AM243x contains 2 MB of On-Chip Shared SRAM, each R5F subsystem has dedicated TCM memory banks. The device also contains DDR4, MMCSD, eMMC, and OSPI peripherals to utilize external memory when needed. Regardless of whether external memory is used or not, the power-up and power-down sequences described in the datasheet must still be met.
Best Regards,
Zackary Fleenor
