  • 384 KB ROM
  • 400 KB SRAM (16 KB for cache)
  • 8 KB SRAM in RTC
  • 22 × programmable GPIOs
  • 3 × SPI
  • 2 × UART
  • 1 × I2C
  • 1 × I2S
  • 2 × 54-bit general-purpose timers
  • 3 × watchdog timers
  • 1 × 52-bit system timer
  • Remote Control Peripheral (RMT)
  • LED PWM controller (LEDC)
  • Full-speed USB Serial/JTAG controller
  • General DMA controller (GDMA)
  • 1 × TWAI®
  • 2 × 12-bit SAR ADCs, up to 6 channels
