Special Layout Considerations for SRAM Octal D-type transparent latches (total of 2) are needed to interface the microcontroller to the SRAM. Both the SRAM and the latches operate at the same voltage as the microcontroller’s I/O voltage (3.3v).

Special Layout Considerations for Microcontroller The core voltage is 1.2v, whereas the I/O voltage is 3.3v. The SPI port needs to connect to two different devices. Current limiting resistors are needed to protect the I/O pins used for the SRAM and the SD-Card.
