TIDUDO6B May 2019 – October 2020
U16 is currently not mounted on the TIDA-01580 board. The user can mount it if external-data log memory is required. When selecting the memory, the user must check the IO_SUP value and operating VCC for the memory.
The TIDA-01580 board has a provision for external memory connection over SPI, as shown in Figure 2-20.
Table 2-13 lists the connections between the memory chip and the CC2640R2F device.
