2.4GHz
module
support HomeKit
M32 supports up to four 16-MB of external QSPI flash and SRAM with hardware
encryption based on AES to protect developers’ programs and data.
M32 can access the external QSPI flash and SRAM through high-speed caches.
• Up to 16 MB of external flash are memory-mapped onto the CPU code space.
3.3 Crystal Oscillators
The M32 Wi-Fi module already embedded the 40 MHz crystal oscillator.
