The CPU runs code from internal 360K SRAM so it operates at the full 180 MHz rate. Code is downloaded on boot from an 1MB QSPI (larger sizes upto 16 MB are available). Internal AES encryption can protect code from duplication and includes another Physical Unclonable Function.
Internal peripherals include dual USB, 8 timers, upto 11 serial devices (configurable as SPI, UART, I2C or 2 can be I2S), Watchdog timer, RTC timer, and 5Msample 12 bit A/D.
The board is compatible with Arduino shields, including the 3.5" TFT touchscreen LCD which is included in the evaluation package.
