Highlights
- The functional block diagram of the SoC is shown below.
- Note: first check this page
- CoreMark® score:– 1 core at 240 MHz: 613.86 CoreMark; 2.56CoreMark/MHz
- – ULP-RISC-V coprocessor– ULP-FSM coprocessor
- Note: They are 2 ULP coprocessor?
- Cryptographic hardware acceleration:– AES-128/256 (FIPS PUB 197)– Hash (FIPS PUB 180-4)– RSA– Random Number Generator (RNG)– HMAC– Digital signature
- Note: learn more about that part
- In Table 2-3 IO MUX and GPIO Pin Functions and Table 2-4 RTC and Analog Pin Functions some pin functions arehighlighted . The non-highlighted GPIO or RTC_GPIO pins are recommended for use first. If more pins areneeded, the highlighted GPIOs or RTC_GPIOs should be chosen carefully to avoid conflicts with important pinfunctions.
- Note: how to choose pinout
- VDD3P3_RTC Input RTC and part of Digital power domains
- Note: we need to use this to have RTC on while shutdown all other peripherals
- Only RTC is powered on. Wireless connection data is stored in RTC memory.
- VDD3P3_RTC 2 Recommended input voltage 3.0 3.3 3.6 V
- Note: But RTC voltage has 3.6V absolute maximum
